Msi motherboard connection. Connector connection rules:

Connecting the computer start button to “motherboard

Self.assembly of your personal computer can sometimes drag on for a very long time. If with connecting the main devices to the PC everything is quite simple and clear, then connecting the motherboard and buttons or indication may seem like a very difficult process. Below we will consider all the main nuances of connecting this unit to the motherboard.

We offer you to familiarize yourself with the list of basic preparatory stages that will greatly simplify the procedure for connecting the keyboard and reboot keys to its main board:

• familiarization with the instructions for the motherboard (if you do not have a printed option of documentation, then it can be downloaded in electronic format on the official website of the manufacturer);
• It is necessary to find the wires that are connected to the connectors (these wires are placed in the front compartment of the system unit, and at their ends there are black plastic connectors);

The inscriptions that are present on the main board and connectors will help you navigate when searching for the desired elements. For example, near the port responsible for the inclusion and reboot keys, either “f_panel” or “Panel1” will be written.

Connection of the front panel integral

If you carefully studied the layout of the motherboard of your computer, and also found all the necessary connectors and ports, then it is time to compare them among yourself. You should start this procedure with connectors that are responsible for the inclusion and reloading of the system. On their buildings, the inscriptions “PowerSW” and “Restartsw” are applied, respectively. We combine these connectors with pins, near which the following designations are present: “PWRBTN” and “Reset”.

Next, connect the computer indicators. It is necessary to find the connector “PLED.” and stick it into the appropriate pin on the board. Connector, which is signed as “PLED”, connect next to the previous.

The HDD indicator displays the signature with the signature “HDDLED”. It must be stuck in Shtepsel “Hdled.”.

If you accidentally confuse the polarity of the indicators, then no fatal consequences will occur. To solve this problem, you will need to connect the connector with the other side.

If you do not know how to connect the front panel of the case to the motherboard, then in this article you will find all the information about connecting the power buttons and rebooting the computer, the indicator of access to HDD, USB-sgs, etc.D.

How to connect a motherboard to the front panel

The right way is to spy the connection in the instructions for the motherboard (manual). If it was not at hand, you can go to the manufacturer’s website and drive the motherboard model in search. there you will find a manual in electronic form. Strictly follow these instructions, and you will succeed. Do not worry if you connect something wrong-in the worst case, the connectors and buttons of the front panel of the case will not work until you connect them correctly.

The inclusion and reboot buttons, connectors for flash drives and other USB devices, headphones and microphone located on the front panel of the case are connected to the motherboard with wires with 1-2 contacts (PIN). They are connected in a certain sequence to the corresponding connectors of the motherboard. Most often, cables and connectors have different markings, color, inscriptions.

There are main types of cables connected to the motherboard:

• PowerSW (PWR). the power button, has 2 PIN, a red, green or white cable (less often black or yellow)
• Resetsw. the reboot button, has 2 PIN, most often yellow
• Powerled and Powerled. a power indicator, has only 2 PIN or 3 PIN, there are different colors
• H.D.D LED. an indicator of loading a hard drive, also has 2 PIN. By the way, this cable may not be

USB and sound connectors are used by separate cables, and are connected to separate connectors of the motherboard (JPF1, JPF2, and T.D.). Below we will give a table in which you will find the most common options for connecting the most popular brands among the ASUS, MSI and GYGABYTE motherboards

Hi all! In this article I will clearly show how to connect the buttons (Power, Reset) and the front panel (f_panel, f_audio and f_usb). It’s not cunning, but it costs your attention. In the beginning a couple of tips: I will analyze this case on an old motherboard from Gigabyte Model GA-945GCM-S2C model. I must say right away. the connection schemes painted exclusively for this article and on a specific example, the colors of the wires will differ in you. The main thing is to understand the meaning of the connection and embody (check) on your PC.

In this picture, the motherboard connectors for connecting connectors are displayed.

Basically (there are exceptions) under the connectors with small print, the connection procedure and polarity are written and polarity. In my case, it is indicated:

PWR_LED (three connectors). indication of the computer turned on;

HD- (IDE_LED, HDD_LED)- LED to turn to a hard drive;

Speak- (Speaker)- the same signal (s) that emits a computer when turned on if an error is detected.

Two wires are suitable for each connector:

In this case, white is a minus “-” or Ground (Earth). And color “”. The Connector Speaker (black, red)-black “”, and red “-” “. To determine the polarity of the connectors, it is enough to turn it over on the back. we see a small black triangle on the against one wiring. this is “”.

We move on to the next stage, connecting the front additional USB. connectors and cartriders to the F_USB2 and F_USB1 connectors (there is no difference, but it is better to start in order). If the Connector is already “soldered”, t.e. All wiring are collected in one block. the process is greatly simplified.

We just connect this “large” connector consisting of: eight wiring, one empty and one sealed connector (only ten) so that an empty connector coincides with a sealed nest in the Connector. (cm. screenshots)

Ah, if you have a bunch of wires as in the picture, I will draw a visual schematic 🙂

Here we see: Power (power. 2 pcs.), GND (Ground. “Earth” 2pcs.), D3 (plus), d3- (minus) on one port usb and d2 (plus), d2- (minus) on another port. As you have already guessed, two Power connectors are identical and they can be changed in places, as well as GND. The main thing is not to confuse Power and GND in places.

So now it remains to understand the connection of f_audio connectors for the microphone and headphones.

Again, if you are lucky and a large block with 10 nests goes from the front panel, we just insert it (you definitely won’t make a mistake here). I have a more interesting case. ) Ah, these are the connectors: SPK R (the output of the right channel to the front panel), SPK L (exit of the left channel to the front panel), MIC (microphone output to the front panel) and GND.

So everything is connected. Thank you for your attention, good luck.

If you have wires, the names of connectors (pads), etc. etc. Do not be lazy, download the manual (management) from the official website of the manufacturer of your motherboard and there 99% find the connection schemes for all f_panel, f_audio and f_usb.

How to connect the inclusion button to the motherboard: detailed instruction

In the process of self.assembly PC, special attention is paid to the correctness of the connection of control elements available on the front panel to the maternal board placed inside the case. An error in switching connectors (connectors) with response parts located on the motherboard will not allow supplying stresses to PC (will lead to the impossibility of turning it on). A de.energized computer in this case turns into a useless thing. In this article you will learn how to connect the computer to turn on the motherboard correctly button.

Management elements

On the front part of the PC case, all the necessary controls are located, including the buttons, connectors and indicator bulbs, according to which the state of its functional nodes is evaluated (see the photo on the left). Not only the correct operation of the computer depends on the correctness of their connection, but in general. the possibility of its functioning.

One of the most important elements in this kit is the button responsible for feeding power to the modules and PC nodes (photo on the left). The train from it is “thrown” along the case to the motherboard located in the system unit.

Additional information: Other names of this working module. the system board or Main Board (literally. the main “board”).

When you press the power button located on the PC front panel, the control signal is supplied to the launching unit of the system board. It is he who provides the supply of supply voltages to all other working modules (including the motherboard itself). In order to ensure the correct connection of the computer to the network before switching its launch elements, a certain preparation will be required.

Preparatory procedures

To correctly connect the PC PC to the motherboard, you will need to thoroughly prepare for this operation, including the preparation of all the necessary tools.

Important! The mention of the tool is not by chance at all, since in some PC (and system boards) models, the train is almost impossible to connect the train from the button manually.

The preparatory measures include:

A careful study of the instructions attached to the motherboard itself.In its absence. searching for information on connecting PC modules of this model.

Preparation of a tool that may be required when switching a train.

The main attention when studying paper or electronic instructions should be given to the scheme of the motherboard with the specified contact group (the train from the button will subsequently be connected to it). It is usually placed from the edge of the board or closer to its center (between the slots of the expanders).

Please note: in the same scheme, you can find the wiring of the train of the train, which is useful if there are no contact designations (photo below) on the system board.

From the tools you need to prepare a thin tweezer necessary to hold the hollit of the train when installing it, as well as a screwdriver with a replaceable bat. It may be required when removing the front panel PC.

Connection instructions

The sequence of operations carried out when connecting the PC electric power supply module looks like this:

First, on the motherboard, you need to find a small connector made in the form of two rows of pins with the inscriptions available under them.

Additional information: In some motherboard, it is located in the lower right corner.

Then, on the connector, according to the rice circuit, contacts are selected for the power switch (their marking. Power SW or PSW).After that, a train consisting of 2 veins with a connector at the end is found on the inside of the control panel.

On the plastic case of this connector, there must be the same designation as under the legs of the board (Power SW). After being it, the user will only have to join the parts of the contact connector of the same name.

The sizes of both are most often very small. so it is quite difficult to manually connect them. Therefore, when treating them, it is recommended to use tweezers.

Reliably holding the response part of the connector in it. the connector, then you will need to put it on the legs of the motherboard with an effort. Upon completion of this operation, the cables from indicators (LEDs), indicated in the rice, should be connected to the corresponding contacts. Like Powerled.

Important remark! When installing the Power SW case, the polarity of the eyeliner does not matter, however, to comply with uniformity, its plane with the inscription should “look” from the outside of the connector.

When connecting the indicator, this factor is necessarily taken into account, since the LED will light up only if the polarity of its inclusion is observed. Not to be mistaken with the appointment of individual contacts on the system board will help more detailed familiarization with the inscriptions that are under them. Such a need arises due to the lack of a single standard for graphic and physical designations (marking).

By the way, you can turn on the computer without the power button, how to do this we said in this article.

Designations of connectors for connecting buttons and indicators

In the immediate vicinity of the contact connectors available on the system board, intended for certain switching, their functional designation is applied. Such forecasting allows when assembling a specific model to prevent errors in connecting the required assembly.

Many famous PC models are characterized by the following designations (marking):

On the board and the power circuit, the already mentioned inscription Power Switch, as well as PSW, PSWITCH or POWERSW.For reset (rebooting). Reset, Restart or Resetsw.

And finally, for the elements of indication of the Powerled, PLLED and PWLLED marking mode indications, and others are used for elements.

Note that other contact groups similar to the previously considered connectors may be located on the main (maternal) board. However, all of them are intended for completely different purposes.

Connecting the front panel of the computer to the motherboard

If you decide to assemble or disassemble the computer, this article will be very relevant for you. It will talk about how to correctly connect the panel of front buttons and USB ports on the system unit, to the motherboard. Here, I will consider not only the general view of the ports to which they need to be connected, but also the correct priority when connecting them.

In fact, it seems, there is nothing complicated in that. But in my practice, even specialists who are quite well versed in computer technology, sometimes stand in front of a system unit, with a bunch of cables and think what and where to connect.

Therefore, then I will show in detail what and in which connector you need to connect, one or another wire for the proper operation of the connected front panel of the system unit. That in the future, at the next cleaning of the computer or possibly replacing the motherboard, it will not be difficult for you to correctly connect all the elements of the system unit to the motherboard.

It is also very important if your front panel with USB ports and headphones and microphone does not work for you. Then, be sure to read it to the end in order to find out how to fix it all the matter and return the working condition to our front USB ports. Because, the malfunction may consist in that they are simply not physically connected to the motherboard.

Connecting the front panel, buttons and indicators block

The buttons and reloading bulbs block are connected to the motherboard using four connectors, which are connected to one solid train. How they look with me you can see below. They should have about the same type and you have. The main thing is that you are looking for those connectors on which similar phrases are written: Power SW, Power Led, HDD LED. Restart SW.

Let’s look separately each connector:

• Power SW (PWRBTN). is responsible for the computer on button;
• H.D.D.LED (HDLED). a hard drive light that constantly blinks when working a computer;
• Power LED. and (PLED). indicator indicating the condition of the computer (enabled or disabled);
• RESTART SW (Reset). Connector responsible for the reboot button;
• Speaker. the speaker is sometimes also present in the cable panel;

Where do all this need to be connected? All connectors will connect to one port, which is located in the lower right corner of the motherboard. Manufacturers usually sign them with such designations as: “f_panel” or simply “Panel”. On each motherboard near such a panel there are small signatures where you need to insert. But still, below I will give you a few examples of what to attach to.

Also, sometimes an additional small speaker is also connected, which announces with a squeak about turning on the computer, as well as the various error of the BIOS and Iron of the computer. Sometimes it is connected with all other connectors, but as a rule, a separate four peony connector is given to it.

Everything, with the buttons block finished, now you can proceed to the front USB and audio outputs.

Connection of the front panel of the system unit

Sound connectors and USB are very similar to those that we connected for buttons and indicators. But their most important difference is that they are already immediately connected in one, and you will not need to take it when connecting and connect it one at a pin.

You can also find a place for connection at the bottom of the motherboard with signatures (F_usb1, 2). There can be two or more on the motherboard, but in which it does not matter, they will work the same. The main thing you need to do is take a connector with the signature “F_USB” and put in the corresponding connector. You cannot make a mistake, because if you try to insert the wrong side, you simply will not succeed and turning over the other side, I think that everything should become in place.

Be sure to pay attention if you have a USB 3 on your computer’s front panel.0, then you will need to connect it to the corresponding connector. Where he is you can find out in the book for the operation of your motherboard. I also want to pay attention to what if USB 3.0 will be connected to the standard connector it will work, just the transfer speed will be the same as on USB 2.0.

Connection of the front panel of sound to the motherboard

With sound, the situation is similar to USB. Here, too, connectors are connected into one, which will easily and without errors attach it to the motherboard. The connector itself is, as a rule, side by side with USB ports and is indicated by the following abbreviations; AAFP, Audio, A_Audio.

Taking a connector with the inscription “HD Audio” or “AC 97”, we connect an example of which I indicated above in the connector with one of the signatures with one of the signatures. If after connecting the headphones and the microphone still does not react, then in the bios it is worth checking the settings of the front audio panel. Sometimes it happens that the system uses the “AC97” driver, and the BIOS indicates “HD Audio” that, due to non-correspondence, to bring our audio outputs into the non-working state.

Connecting additional fans

I think that information about how and where you can connect additional fans will not be superfluous for you. I mean, those coolers that can be located on the back of the case or stand in its lower part. The procedure is the same as before, take the connector connect to the connector. True, the location of the connectors differs from everyone else. In most maternal boards, it is somewhere around the middle and has the following look.

Also, as in all other cases, each connection place has its own signature (sys_fan, Cha_fan). I also want to note that on the connector itself there is a small wall that serves as a hint for the correct connection. The connector itself should sit easily, if you have it not, most likely you are trying to join it with the wrong side. Stuff him there by force, I do not recommend that you just break it off.

Step 3. Connect the chips of the front panel connectors to the corresponding motherboard connectors

Further, 2 options for developing the situation are possible.

Option one

On your motherboard, all contacts are signed and you just put on the chips on contacts by observing the appropriate names and polarity. Polarity is important for HDD LED (IDE LED) and Power Led. On the Plus Contact board, it is signed as “”, and on the plowed contact, this is a colored wire (different from white and black). Either if all the wires are from the front panel of black, then they will also be signed on them.

Polarity and. when connecting PLED and HDLED

Even if you confuse polarity, then nothing terrible will happen. Just on just when turning on, the power button will not light up and the LED of the Light disk activity will not blink. In this case, just turn the non.working chip upside down on the contacts of matches. boards to change polarity.

Option Second

Contacts on the motherboard are not signed, as in the photo below.

Contacts of connection of the front panel on the motherboard without signatures

In this case, you need to determine the model of your motherboard, find it on the Internet and see the documentation on rolling buttons, indicators, USB and sound outputs.

Stages of connecting the front panel to the motherboard

Consider the main points in connecting the front panel to the “motherboard”:

Stage 1

First of all, you need to find the main train with 4 (sometimes 5-6) plugs. Some difference in names, color, etc. is possible. D.There can be much more plugs, it depends on the variety of the front panel/motherboard. But following the scheme on the “motherboard”, it will not be difficult to connect them all unmistakably. The description of the scheme is a little further in the article.Located in the photo on top of the plugs imply the following:

• PowerSW (or PWRBTN). activates manipulations with a computer on/off button on the panel.
• H.D.D.LED (or HDLED). a light bulb when the hard disk is working.
• Powerled and. (or PLED). a light bulb on the computer/disable button; If the computer works, then burns, and vice versa; can be a whole plug.
• RESTARTSW (or Reset). activates a computer reboot button.
• Speaker. a small speaker that makes a squeak if there are problems in the computer work.Connecting Speaker of the plug is desirable, since such a squeak-signal helps to save the motherboard from the breakdown, instantly notifying the user about the presence of critical problems, about the incorrect connection of any plug or connecting into the wrong nest. Also, this sound effect allows you to generally evaluate the work of the computer.The names of these plugs may vary, but not much. For example, instead of PowerSW, PW can be indicated. And instead of restartsw. just res. Comparing the first letters of the names of plugs and connectors, you can easily understand which STETER where should be connected. Colors also help, which often correspond to the color of cables from plugs. But first of all, it is necessary to compare the names, followed by colors, because they can vary, unlike the names.

Stage 2

Pluters must be inserted into one large nest (frontpanel or f_panel) on the edge of the motherboard. Usually it looks like this: to connect the wires into the connectors with the right side, you can just look at the plug itself. If one contact (iron “knit”) does not have enough, then you need to attach this place, in accordance with another empty place on the motherboard, in the connector. Side fasteners on some nests and plugs can also help (fasteners should be on one side). Additionally, you can navigate the colors in the connector or visual hints in the form of brilliant contacts and t. P. As a rule, plugs are connected by the inscription “on themselves” or towards inscriptions on the motherboard (scheme).When all of the above is absent, you can insert a plug with any side. The main thing is that the process goes smoothly and without the use of gross force. If the plug connects in the connector does not occur even with slight efforts, then the wire connection occurs incorrectly.

Below, under color connectors, the places where the plugs are connected are schematically indicated (signed). For example, according to the scheme under the connectors, which is responsible for the PowerSW computer button (PowerSW) should be connected to the red nest (the second on the left, from above, signed as PW). All other wires are joined in the place indicated in the scheme accordingly.

In the documentation accompanying to the computer, if it is available, there are also tips for connecting plugs in the nest. These hints look like this: as can be seen in the figure, in the documents even the names of plugs and abbreviations in the scheme are deciphered. For example, resetswitch. “Re.loading button”) and t. D.

Stage 3

Plugs responsible for the operation of USB ports on the front panel are connected a little differently and easier. The USB stoker looks like this: the connector for this plug can have the following names:

• F_usb1/f_usb2;
• USB1/USB2;
• or all nests for this plug can be called just USB.It does not matter where the wire will be connected, since all the USB-GNED is completely identical. Except USB 3.0. If the front panel has just such a USB-stroke, then the connector on the motherboard must be sought with the corresponding name. Often this is what it is called. USB 3.0, but there may be exceptions to F_USB30 and T. D.An interesting fact is that if you insert a USB 3 plug.0 in the standard USB connector, the device will work. But its speed will not be like USB 3.0, and below, because the connector supports only the standard USB (2.0). If suddenly there is no nest under the USB 3 on the motherboard.0 or it cannot be found, this method can help.

Stage 4

Sound connection (headphones/microphone) on the front panel is identically described earlier than the processes.A plug is taken from the front panel with the name AC97 or HDAUDIO and is inserted into the connector with the corresponding inscription:

If the sound has not appeared, perhaps the problem lies in BIOS. Reloading the computer and “getting into” the BIOS system, you should check the front panel and its characteristics. Sometimes it happens that the HDAUDIO plug is connected, and the BIOS recognized the connected device as AC 97. This defect is decided by the change in the BIOS of the wrong driver to corresponding to the one connected in the motherboard.

Basic devices when connecting to the motherboard

Fixing the motherboard on the case. Usually there are 4 racks (sometimes more, but 4 will be enough), on which you need to fix the motherboard with bolts. With this procedure, problems cannot arise, t. to. The main and the only condition is to be able to use the screwdriver. You need to tighten the bolts tightly, but without applying excessive efforts, so as not to break the motherboard. If the device is stably staying in the housing and not “driving”, this is more than enough.

Racks are needed to separate the motherboard from the body: they protect it from short circuit, contribute to additional cooling, and t. P.

Food. First of all, regarding devices, you should connect a power supply unit. Its installation on the case does not cause problems. Since many remaining cables will be connected to other devices, in addition to the motherboard itself. This will provide unhindered access to the accession of other devices.

Connect the power unit with a connector to 24 contacts (sometimes 20). It will not work to confuse him with other loops (he is one). This connector looks as follows:

The nest for the power supply is usually located on the edge of the motherboard. It is impossible to confuse it. this is the only connector of such a width into two rows. No other device will be connected there. When connecting, this should be done carefully, slightly pressing. to the click, so that the latch on the connector and the train coincide. The rest of the train have fixators in the same way.

All other loops from the power supply are completely different from each other, so there will be no questions which cable to which device is intended. If you doubt, look for guide elements and designations. Or use the documentation for the purchased power supply/maternal board.

In no case do not connect the train to 20 contacts in the connector for 24 contacts and vice versa. This will cause irreversible damage, the repair of which will be very expensive. Rule number one. always check if a specific power supply is suitable for the motherboard model used before buying. This applies to any other devices except USB 3.0.

Winchester. A train from a hard disk is wide and not very. It all depends on the plug. There are two varieties: IDE and SATA.

The black connector (left) is inserted into a hard drive, and blue (right). into the motherboard. This is what the place on the motherboard looks like where you need to insert the IDE plug from the train (blue connector, between two black above and below).

Regarding the SATA of the train, it is much smaller and inserted into the connector with the designation “SATA1”, “SATA3”, etc. D. The designations can be any, but always contain the keyword SATA. It all depends on the model of the motherboard.

The discrotor, by the way, is installed in the board in a completely identical way. But his IDE train joins the shorter connector (in the previous picture it is black, located just above blue). Otherwise, including SATA, a connector, connecting a disco to the motherboard identical to connecting a hard disk.

This is just an example, since such connectors can be of different shapes (vertical, horizontal) and are located in different parts of the motherboard.

You also need to connect the connector from the power supply, taking into account the guide elements. There are usually no problems with this. The connection of the hard drive to the motherboard is completed on this.

Video card. Connecting a video card to the motherboard is a completely unlikely process, but with specific tricks that you need to know so as not to break the fixers. On most motherboard there are clamps on the likeness of the following:

They are completely identical to the fixers on RAM. But sometimes there are not quite obvious fixers, to know about the existence and principles of work which every user needs. Before connecting a video card, carefully study the operation of the latches. If necessary, disconnect (or attach, if the mechanical type clamps) the device may arise problems.

The video card itself is shown under the number 8:

Vertical blue connector and there is the place where the video card is inserted. Blogging a piece. a standard latch. It is impossible to make a mistake, since it will not work to insert the video card due to the guide cut on the connector.

Further, an additional power source in the form of a cable from the power supply is connected to the video card (for the vast majority of modern models). Often, this is a connector with 4 contacts, but there are 2 wires for 2 contacts or 1 wire, but for 8 contacts. It all depends on the model and manufacturer of both the video card and the power supply. At the end, a cable from the monitor is connected from the outside of the system unit. the video card is completely ready for use.

Cabinet fans (coolers). To connect these devices, it is enough to fix them with bolts in appropriate places (selected individually or following the documentation) and connect to the motherboard:

• CPU_FAN (CPU. central processor; fan. fan). The nest is designed to connect the cooler to the processor. Do not try to connect a train into it for 4 contacts if there are only 3 holes for them and vice versa, it is better to purchase a fan suitable for this connector. If the cooler is incorrect, the cooler can quickly burn out or stop working, and this threatens overheating and breakdown of the central processor. Which, by the way, is the most expensive device in the computer.
• Sys_fan (System fan. system fan). The nest is created for all other fans in the housing. Cools for blowing and other cooling in the system unit should be connected to this type of connectors (the sequence does not matter, you can connect to any of them). Typically, there are several such connectors, depending on the model of the motherboard (sys_fan1/2/3 and t. D.). All of them are signed on the “motherboard”, to find it will not be difficult.

The main thing in connecting the motherboard is an understanding of the designations, a guide on guide elements (tips; lack of contact, cut in a nest, false “pin” in a plug, etc. D.) and neat connection. If you follow these rules, then the next time you will not need any help in connecting the “motherboard”. everything is so easy and simple.

How to connect the front panel to the motherboard correctly

The front panel on the system of the system unit is in no way connected with the rest of the “insides” of the computer. So, with manual shutdown for the purpose of cleaning or, a little more complicated, when replacing the motherboard, you will have to independently connect the front panel. Then it will be described in detail how to do this as correctly as possible.

Consider the main points in connecting the front panel to the “motherboard“:

Stage 1

First of all, you need to find the main train with 4 (sometimes 5-6) plugs. Some difference in names, color, etc. is possible. D.

There can be much more plugs, it depends on the variety of the front panel/motherboard. But following the scheme on the “motherboard”, it will not be difficult to connect them all unmistakably. The description of the scheme is a little further in the article.

Located in the photo on top of the plugs imply the following:

• PowerSW (or PWRBTN). activates manipulations with a computer on/off button on the panel.
• H.D.D.LED (or HDLED). a light bulb when the hard disk is working.
• Powerled and. (or PLED). a light bulb on the computer/disable button; If the computer works, then burns, and vice versa; can be a whole plug.
• RESTARTSW (or Reset). activates a computer reboot button.
• Speaker. a small speaker that makes a squeak if there are problems in the computer work.

Connecting Speaker of the plug is desirable, since such a squeak-signal helps to save the motherboard from the breakdown, instantly notifying the user about the presence of critical problems, about the incorrect connection of any plug or connecting into the wrong nest. Also, this sound effect allows you to generally evaluate the work of the computer.

The names of these plugs may vary, but not much. For example, instead of PowerSW, PW can be indicated. And instead of restartsw. just res. Comparing the first letters of the names of plugs and connectors, you can easily understand which STETER where should be connected. Colors also help, which often correspond to the color of cables from plugs. But first of all, it is necessary to compare the names, followed by colors, because they can vary, unlike the names.

Stage 2

Pluters must be inserted into one large nest (frontpanel or f_panel) on the edge of the motherboard. It usually looks like this:

To connect the wires into the connectors with the right side, you can just look at the plug itself. If one contact (iron “knit”) does not have enough, then you need to attach this place, in accordance with another empty place on the motherboard, in the connector. Side fasteners on some nests and plugs can also help (fasteners should be on one side). Additionally, you can navigate the colors in the connector or visual hints in the form of brilliant contacts and t. P. As a rule, plugs are connected by the inscription “on themselves” or towards inscriptions on the motherboard (scheme).

When all of the above is absent, you can insert a plug with any side. The main thing is that the process goes smoothly and without the use of gross force. If the plug connects in the connector does not occur even with slight efforts, then the wire connection occurs incorrectly.

Below, under color connectors, the places where the plugs are connected are schematically indicated (signed). For example, according to the scheme under the connectors, which is responsible for the PowerSW computer button (PowerSW) should be connected to the red nest (the second on the left, from above, signed as PW). All other wires are joined in the place indicated in the scheme accordingly.

In the documentation accompanying to the computer, if it is available, there are also tips for connecting plugs in the nest. These tips look like this:

As can be seen in the figure, the documents even decipher the names of plugs and abbreviations in the scheme. For example, resetswitch. “Re.loading button”) and t. D.

Stage 3

Plugs responsible for the operation of USB ports on the front panel are connected a little differently and easier. Looks like a USB stroke-like this:

The connector for this plug may have the following names:

An interesting fact is that if you insert a USB 3 plug.0 in the standard USB connector, the device will work. But its speed will not be like USB 3.0, and below, because the connector supports only the standard USB (2.0). If suddenly there is no nest under the USB 3 on the motherboard.0 or it cannot be found, this method can help.

Stage 4

Sound connection (headphones/microphone) on the front panel is identically described earlier than the processes.

A plug is taken from the front panel with the name AC97 or HDAUDIO and is inserted into the connector with the corresponding inscription:

If the sound has not appeared, perhaps the problem lies in BIOS. Reloading the computer and “getting into” the BIOS system, you should check the front panel and its characteristics. Sometimes it happens that the HDAUDIO plug is connected, and the BIOS recognized the connected device as AC 97. This defect is decided by the change in the BIOS of the wrong driver to corresponding to the one connected in the motherboard.

The described method of connecting the front panel is suitable for any motherboard: MSI, GIGABYTE, ASUS, ASROCK. The only differences, as already mentioned, can be hidden in the inscriptions on the nests and connectors, their location on the motherboard, color coloring, etc. D. Otherwise, the connection process will always be identical.

How to connect the motherboard to the front panel. instruction

The front panel of the system unit is connected to the computer motherboard for the operation of buttons, indicators and all connectors. The developers have only those connectors on the front panel that can be turned on and disconnected by hot, without disconnecting the computer. These are all USB connectors, as well as headphones with a microphone. It is not necessary to connect all these connectors, but the outputs of buttons and indicators are always needed. Otherwise, the computer will not work. Here we will consider how to connect the front panel to the motherboard on various models.

The connectors outside the system unit have labeling and special keys that do not allow the wrong cable to put in the connector. There is no such protection inside at all. Any wire can be connected to any contact. The same pin connectors with a step between contacts 2.5 mm are used everywhere. Therefore, all connections must be verified by inscriptions on wires and on the motherboard itself. In order not to designate each wire, manufacturers adhere to several standard connection schemes. It turns out a rectangular array of contacts in two or three rows.

To find the reference angle, manufacturers leave the key. unused contact.

Connecting all buttons and indicators of condition

The motherboard has three contacts for connecting the front panel: a group of indicators and buttons (about 15 contact pins), F-Audio (front) and USB, which are usually several on modern models. All of them are connected by wires with the corresponding inscriptions. Color marking is also popular, but it is optional.

The first stage of connection. we identify these three groups on the motherboard and on wires in the system unit.

You need to focus on inscriptions on connectors and on the board. All this is quite simple if you figure it out. Additionally, you need to clarify: whether the motherboard has a built.in BIOS speaker. If it is, then there are no connectors for its connection. A group of contacts of indicators and buttons has 3 standard executions. Modern motherboards use a scheme with a built.in speaker. Exactly 8 contacts are active in it. 2×2 for LEDs and 2×2 for the “Power” button “Reset”. The motherboard with an external speaker has 10 mandatory contacts.

In this case, the contact platform has 17. Of these, 3 remain empty on top (key), and the BIOS speaker is connected to 4 contacts at the edges with a missing 2 contact. The 4 contact platform for the dynamics can be executed separately and do not enter the general group. Only two contacts are used in it in the same way. Contacts on the inscriptions on the board are identified. The exact location of contacts on the motherboard can always be clarified in its specifications. The technical manual is easy to find via the Internet. The main thing is to accurately introduce the brand of the motherboard.

The following connectors must be connected to the front panel (in brackets. the inscription on the identification board):

• button “Power” (indicated as PW, PWR, MSG, LD);
• “Reset” button (marked as “SW” or just reset);
• LED Power indicator (LED);
• LED indicator of hard disk activity (LED HD);
• Bois speaker (if any, is designated as SP or Speaker).

Contact group is often designated as “Panel 1”.

After connecting the mandatory contact group, we move on to connect the front panel connectors with a hot shutdown. These are USB and audio connectors.

The process of connecting the front panel of the system unit body

USB connectors on motherboard are always the same. This is a group of 9 contacts. Only 8 are active of them, and the 9th is used as the key. Significant currents are transmitted through the USB port. There are not 10 milliamps, as in the LEDs of the front panel. The port does not tolerate the wrong connection and immediately burns out. When connecting it, you need to be very careful.

It is necessary to strictly comply with the general rules: the appointment of contacts in the upper and lower row is strictly the same, they simply belong to different ports and should not be confused; from the side of empty contact (key) upper and lower contact. Earth; from the opposite side of the contacts “Nutrition” (indicated like “5V”); two contact media. data tire. The wires are usually green and white. For them, too, the correct sequence is very important.

All groups of 9 USB contacts are labeled as “USB1”, “USB2” and further by numbers. On modern motherboards, their significant number. Ports work at the same speed, regardless of their number. In architecture they are all the same. The numbering is included only as the designation of contact groups on the board. Sometimes the USB connector is made by a whole cable without dividing into separate contacts.

In this case, you just need to connect a four.pin fork so that the black wire (Earth) is from the key.

Connecting the front sound panel to the main board

The sound connector has 4 contacts, and their real number can be larger. This is done for noise immunity. Tire “Earth” connects many times. These are analog connectors, so the length of the wires (longer wires. more noise and interference), especially for the microphone there is critical. Typically, the contact group is located near the sound chip. It is marked like f-audio. If there are no jumpers on it, then the chip supports work on many channels.

How to connect the power button to the motherboard

Well, components in the collection, it remains to fit one to another and Hello, a new computer! If with connecting the processor, memory, graphics cards usually does not arise, then small wiring connecting the contacts of the motherboard with elements on the body of the system unit, force the back of the head for a long time: which of them leads where?

Sipetal contacts of buttons, indicators, system dynamics and audio connectors look the same, and each manufacturer of the motherboard places them on their products differently. Today we will talk about how to correctly connect the computer button to the motherboard and not burn nothing.

Front Panel

The area of ​​location of the power buttons (Power) and rebooting (Reset), as well as power indicators, disk activity, sleep and some others on the system unit are called the front panel. Front Panel. On the motherboard, she corresponds to the contact group f_panel.

F_panel may look like in a photo where each contact is painted with a certain color, or it can be plain. The number and location of the pins on it is also not the same, so the connection scheme for the front panel for motherboards, for example, ASUS, is not suitable for Gigabyte and vice versa.

On some models, the hits of the front panel is signed, which greatly facilitates the process of assembling the system unit.

But most often they are simply marked by serial numbers, as in the first photo. In this case, you can’t do without instructions.

Power button (Power)

From the power button on the front panel of the system unit, 2 wiring departs, which end with a rectangular connector with two holes and the inscription “Power SW” (Power Switch). Do not confuse it with the Power Led Connector, the latter is designed to connect the computer power indicator.

The computer does not turn on with CD/DVD drive

The Power SW connector is connected to a pair of contacts on f_panel, which are signed on the connection diagram in the same way. Some Power Switch schemes are designated as PSW, PWR, PWR BTN, PWRSW or ON/OF.

Contacts of the front panel have polarity, that is, one of the pairs of conductors is connected to the conclusion “”, and the second-to “-”. The Power Switch connector also has a minus and plus, however, it can be connected to the motherboard with any side, since it works to close/open the circuit.

And what will happen to the computer if you are mistakenly connect the power button to another connector, for example, indicators or system dynamics? It’s okay. it simply will not start, because the switching circuit that closes with pressing the button will remain open.

In the same way, you should not be afraid of problems if you are mistaken with connecting other elements of the front panel. The incorrectly connected element will simply not work.

On the MSI boards, the F_Panel connector has 10 contacts, Piner Power Switch is indicated by serial numbers 6 and 8.

Fujitsu Siemens

On the 30-pin front-panel Fujitsu Siemens Pins Power On/OF are 25 and 26. Pay attention, the countdown on this board is carried out from right to left.

Lenovo

• On models of motherboards Lenovo with a 14-pin front panel connector, the on button is connected to contacts 9 and 11.
• On models with 10 contacts for Power Switch, Pines 6 and 8 are assigned.

Only the most common options for connecting the Power button to the motherboards of stationary computers are collected here. If not one of them suits you, “fed” the search system: “Model_washi_ Payments Front Panel Connection” and see the pictures found. Most likely, the answer is very fast.

Conventions of the connectors of buttons and indicators

To make it clear, for the performance of what function a specific wire is responsible, manufacturers apply the following conventions to each mini-extension:

• Power SW (Power Switch). a connector that comes from the power button (Power). By pressing this button, a computer is launched;
• Reset SW (Reset Switch). a connector coming from the computer reboot button;
• Power LED. PC power on/off indicator;
• HDD LED. a wire coming from the indicator of the state of the hard disk PC;
• Speaker. a connector for connecting a system dynamics (“squeaks”);
• HD Audio. microphone and headphones;
• USB-USB connector.

We connect the case buttons to the motherboard

For the correct connection of Power and Reset buttons to the motherboard, you need to have instructions at hand. On the payment circuit, you need to find information about the location of the contact block.

In most cases, manufacturers designate it as “f_panel”, “Front Panel” or simply “Panel”. If the instructions are lost, you just need to carefully inspect the motherboard and find this group of connectors on it.

• First, connect the Power SW (Power Switch) power button to the Power Board. The place for him on the motherboard is designated as “pwr_btn”. Since this is a button, not an indicator, the polarity of connecting the power button to the motherboard does not matter. The power button can be connected by any side.
• Next, connect the Reset SW (Reset Switch) forced reboot button. The place for this connector on the motherboard is designated as “reset” or “reset_sw”, it is located directly under the power button. In this case, polarity also does not matter.
• We connect the indicators of the system unit to the motherboard
• Focusing on the scheme from the instructions or the symbols applied to the motherboard, it is necessary to connect the indicators of the indication.

When connecting indicators, it is important to observe polarity, because otherwise they simply will not burn. The board itself indicates the polarity with the symbols “” and “-“.

It should also be present on the connectors. If it is not or not visible, then you should use the hint: the white wire is a minus, color. plus.

The place for the PC (Power LED) on/off indicator on the motherboard is designated as “PWR_LED”. To connect the HDD LED connector. “HDD_LED”.

If, after the computer starts up, one of the indicators will not work, just reconnect the connector, turning it with the other side.

Other connectors coming from the system unit case. Speaker, HD Audio and USB are connected to the maternity board.

Step 2. We find contacts on the motherboard for connecting the front panel

It is worth noting that the connection of the buttons of turning on, rebooting, the indicator of the hard disk and the inclusion indicator of the computer, as well as the speaker (f_panel), is one group of connectors (1 in the figure below), the connection of the front USB (USB) is the other group (2 in the figure below ) and headlines with a microphone (AAFP). the third (3 in the figure below).

On the motherboard they are located approximately like this:

The location of the connectors on the motherboard for connecting the front panel of the system unit

Step 3. Connect the chips of the front panel connectors to the corresponding motherboard connectors

Further, 2 options for developing the situation are possible.

Option one

On your motherboard, all contacts are signed and you just put on the chips on contacts by observing the appropriate names and polarity. Polarity is important for HDD LED (IDE LED) and Power Led. On the Plus Contact board, it is signed as “”, and on the plowed contact, this is a colored wire (different from white and black). Either if all the wires are from the front panel of black, then “” will also be signed on them.

Polarity and. when connecting PLED and HDLED

Even if you confuse polarity, then nothing terrible will happen. Just on just when turning on, the power button will not light up and the LED of the Light disk activity will not blink. In this case, just turn the non.working chip upside down on the contacts of matches. boards to change polarity.

Option Second

Contacts on the motherboard are not signed, as in the photo below.

Contacts of connection of the front panel on the motherboard without signatures

In this case, you need to determine the model of your motherboard, find it on the Internet and see the documentation on rolling buttons, indicators, USB and sound outputs.
