When assembling a computer, be sure to know how to motherboard connect the wires, because without this knowledge nothing will work at all. This stage is carried out when all components are already installed in the case. That is, the motherboard itself, the power supply, the hard drive are in their places. It is also desirable to install the motherboard in the PCI-E slot and screw it to the case. Only now you need to connect the wires to the motherboard. How to do it? We will talk about this now.
How to connect wires to Asus, ASRock, MIS and other motherboards?
It is important to immediately note the fact that the method described below is highly generalized. Different motherboards will connect a little differently. That is, there may be some differences, but the principle remains the same. Let's start by explaining and connecting the body connectors: power button, reset, USB ports.
Connecting connectors
Before from the power supply, you need to connect connectors to it. It is important to understand here that they all have protection against wrong connection, so you need to insert them very carefully, without any effort.
Please note that each connector has a label that describes its purpose. There is also a marking on the motherboard, but it is missing on some models. The description of the terminals can only be found in the instructions for the motherboard.
We connect the first connector marked M / B SW. He is responsible for the power button on the case. It may also be called POWER SW. Take a close look at the motherboard (bottom right), if there are a couple of contacts marked POWER. If there is, then it is on them that you need to fasten this connector. If there is no such inscription, then open the instructions for the board and look for the diagram there.
The second connector marked RESET SW is responsible for the reset button. By analogy with POWER, we connect the RESET SW connector. If there is no indication on the board, then we look in the instructions for the motherboard, which contacts need to be closed.
There are also wires marked POWER LED + and POWER LED-, thanks to which the light bulbs on the system unit case glow. Here it is important to connect them correctly and not confuse plus and minus in places. Be sure to check the instructions.
Do not forget about the USB connectors on the case. If you want to be able to insert flash drives into the sockets on the case, and not directly into the motherboard, then you need to connect the USB connectors. They are marked as USB. The Audi wire is responsible for the 3.5 mm Jack, which is used for headphones or speakers.
Let us remind you once again that it is important to know how to connect the power-on wires to the motherboard correctly. And if you have to forcefully stick the connector, then most likely you are doing something wrong. After the connector wires are connected to the motherboard, you can proceed to the power supply.
Processor power connection
The central processor is placed on the socket allotted for it, and a radiator with a cooler is put on it. No wire is connected to the processor itself. Its power is supplied from the motherboard, and the wire is connected directly to it. The power socket is located next to the processor. See if there is a 4-pin socket nearby. The instructions for the motherboard must indicate its location, but it can be seen even with a cursory examination of the board.
A 4-wire wire is connected to the processor power socket. Usually it is the only one here, so you are unlikely to make a mistake.
Connecting the Motherboard Main Power Cable
This is the largest cable. It consists of twenty connectors (pins), and in addition to it, 4 more separate connectors are attached. It turns out that the motherboard is connected through 24 connectors. And since the only wire with so many pins comes out of the power supply, you can’t make a mistake in its definition. In addition, there is a special latch at the end of the connector that prevents the cable from being inserted incorrectly into the connector.
When connecting, make sure that this design fits into the socket and snaps into place.
Connecting a video card
If you are using a processor with an integrated graphics card, then there will be no video card connection. But most often, users prefer to use powerful graphics platforms that connect via a PCI-E connector and require additional power.
The video card is powered by a 4-pin connector. The place for food, depending on it, can be somewhere on the side, but most often it is located at the back. If the video card is very powerful and demanding on power, then it can also be powered from a 6-pin connector. Therefore, when choosing a power supply, pay attention to which ones and how many wires it has for power. When connecting the card, the connector should click into place - pay attention to this.
Connecting a hard drive
HDD connects to the motherboard via a SATA cable. On the motherboard (somewhere on the right side) there are usually 4 SATA connectors, where it says: Choose the first one and connect a hard drive to it.
A SATA cable has identical connectors on both ends. But this is not enough. The hard drive also requires power and is usually connected to the unit via a 4-pin connector. Therefore, connect a cable with four cores to it. By analogy, an optical drive for discs is also connected, but they are now extremely rarely used.
Connecting RAM
We figured out where to connect the wires on the motherboard, and that the RAM is simply inserted into the connectors and does not require connection through wires. Your board has 2-4 RAM slots. Insert the memory there (note that there is protection against incorrect insertion) and press down a little. The click sound will indicate that the memory has fallen into place.
Well, that's all, now you know how to properly connect the wires to the motherboard, and you can do it yourself. We add that the developers are trying to make their hardware as convenient as possible for connection. Therefore, you will definitely be able to assemble this "constructor", because even if you wish, you will not be able to connect the wrong wires to the wrong sockets. From this there is reliable protection.
Connecting the motherboard is very interesting, albeit individually. After all different models may have different connectors, connector locations and features. However, in general terms, you can give a generalized guide to connecting the motherboard, which I will give below.
In this article, I will give instructions for connecting the motherboard using the example of ASRock P67 Pro3. It may differ in some ways from other boards, so do not be alarmed if you have something different from what I write.
Watch carefully and you'll be fine. And if it didn’t work out, then ask, I will help you.
So, for convenience, I will give a plan-picture, and they will tell you what and where to connect on the motherboard.
In our case, the motherboard is powered by a 24-channel cable, and the processor is powered by an 8-channel cable. Before connecting the motherboard to power, find these cables and plug them into the appropriate connectors.
Connecting cables to the motherboard
Cables to the motherboard and CD drives. Most modern motherboards support two device interfaces - IDE ATA and Sata.
The cables are connected to the motherboard in the appropriate connectors: a large one for ATA, a small one for Sata. I note that IDE ATA supports connecting two devices at once to one port connector, and Sata allows you to connect only one to one port.
Obviously, when the cables are connected to the motherboard, devices should be connected to their free ends - hard drives or CD-ROM drives with appropriate ATA or Sata interfaces.
How to connect the motherboard to the case
Before connecting the motherboard to the case, let's make it clear that this expression means connecting it to the front panel - that is, these are the start, restart, speaker (if any) and indicator LEDs buttons.
Among all the aspects discussed above, this trifle is the most difficult, probably for many, and any general instruction about how to connect the motherboard to the case, I will not give, because everything is different everywhere.
Hi all! In this article, I will clearly show how to properly connect the buttons (POWER, RESET) and front panel devices (F_PANEL, F_AUDIO and F_USB). It's not tricky, but it's worth your attention.
A couple of tips first:
I will analyze this case visually on an old motherboard from Gigabyte, model GA-945GCM-S2C. I must say right away - I drew connection diagrams exclusively for this article and on specific example your wire colors will vary. The main thing is to understand the meaning of the connection and implement (check) on your PC.
This picture shows the motherboard connectors for connecting connectors.
Basically (there are exceptions) under the connectors, the order of connecting the connectors and the polarity are written in small print. In my case it says:
PWR_LED (three connectors) - indication of the switched on computer;
PW- (PWRSW) - PC power button;
RES+ (RESET) - button to restart the PC;
HD- (IDE_LED, HDD_LED) - HDD access LED;
SPEAK- (SPEAKER) - the same signal (s) that the computer emits when turned on if an error is detected.
Connectors look like this (see screenshots)
Each connector has two wires:
POWER LED (green, white);
H.D.D. LED (yellow, white);
POWER SW (black, white);
RESET SW (orange, white);
SPEAKER (black, red).
In this case, white is minus "-" or Ground (ground), and colored "+". The SPEAKER connector (black, red) has a black "+" and a red "-". To determine the polarity of the connectors, it is enough to turn it over to the back side - we see a small black triangle opposite one wire - this is "+".
Let's move on to the next step, connecting the front additional USB connectors and the card reader to the F_USB2 and F_USB1 connectors (there is no difference, but it's better to start in order). If the connector is already "soldered", i.e. all wiring is collected in one block - the process is greatly simplified.
We simply connect this "big" connector consisting of: eight wires, one empty and one soldered connector (ten in total) so that the EMPTY connector matches the SOLDER socket in the connector. (see screenshots)
And, if you have a bundle of wires as in the picture, I'll draw a visual diagram :)
Here we see: POWER (Power - 2 pcs.), GND (Ground - "ground" 2 pcs.), D3 + (plus), D3- (minus) for one usb port and D2+ (plus), D2- (minus) to another port. As you may have guessed, the two POWER connectors are identical and can be interchanged, just like GND. The main thing is not to confuse POWER and GND.
So now it remains to deal with connecting the F_AUDIO connectors for the microphone and headphones.
Again, if you are lucky and there is a large block with 10 sockets coming from the front panel, just insert it (you definitely can’t go wrong here). My case is more interesting... :) And, these are the connectors: SPK R (right channel output to the front panel), SPK L (left channel output to the front panel), MIC (microphone output to the front panel) and GND.
Parts. In this part, we will connect the wires from all components to the motherboard. First, connect the wires coming from the power button, reset, LED power, computer operation indicators and work hard disk.
Details about the wires of the case were described in the article "". For each motherboard, the case wire connection is purely individual, so open the manual for your motherboard and find the wiring diagram there. Next, following the diagram, connect the body wires.
If there is no instruction, then it can always be found on the Internet on the website of the motherboard manufacturer.
Below is a photo of the connected case wires.
Now we connect an additional processor power connector. There is a special output with 4 wires, so we connect it to an additional processor power socket.
The figure shows a white four-pin connector. It has a special key that prevents incorrect connection.
Next, connect the main power cable to the motherboard. On modern motherboards, it is also necessary to connect an additional four-pin connector, which is usually separate from the main one. In order to make it easier to connect, pick up the main connector and combine it with the additional one, and only then connect the entire structure to the motherboard.
We connect all this as a whole, it should come out so that the special latch will snap into place on the ledge made on the motherboard connector.
Now we insert the bar into a special slot random access memory, follow the key, cutout on the bar.
Gently press on the bar from above until the clips snap into place, be careful not to press too hard, so that the motherboard would bend.
Connecting the cable to the motherboard.
Now we connect the power of the hard drive.
and optical drive power
It remains only to insert the video card into the slot (Figure below)
Fasten with a screw to the body.
If necessary, we connect additional power to the video card (depending on the model of the video card)
Now we have everything assembled, once again we will fix all the hanging wires, check the reliability of the connection and we can safely close the side cover and connect the computer to the monitor, keyboard, mouse. We connect the power cable to the outlet and press the computer start button. If you do not have a hard drive operating system then the computer will pass the POST test and give you information that it cannot find a boot device.
This concludes the article on assembling the computer myself. You can proceed to Windows.
The power supply is an integral part of any personal computer. Thanks to the block, electricity is conducted to the motherboard, the central processor and any other peripherals.
When installing this device in no case do not connect it to the power supply.
To connect you will need a cable with connector 24pin, however, older models use 20+4 pin. Such a connector is always included with your power supply, and you do not need to buy it separately.
Standard 24 pin connector
Connector 20+4 pin
This cable has a small latch on one side, which allows you to correctly position the connector when connected to the motherboard.
When connecting the module it does not follow apply great force so as not to damage any of the devices. However, it is necessary to achieve a tight fit in the socket on the board, as well as make sure that the latch clicks and is securely fastened.
Fixed 24 pin connector Thus, we connected two main devices together, which will allow us to supply power to the motherboard.
Next, you need to supply power to CPU. Per this function answers 4 pinconnector. For more powerful processors used 8 pinconnector.
Standard 4 pin connector
8 pin connector for more powerful processors
Connection this module likewise the contacts mentioned above. Plug must be plugged into socket click clamp that ensures a tight fit of the cable.
Thus, we have established the supply of electricity not only to the motherboard, but also to the central processing unit.
Connecting the front connectors
Buttons are usually present on standard system units. food and reboot personal computer, as well as indicators(bulbs). Them connection to the motherboard is carried out after 1-2 pins connectors that need to be connected correctly. These cables have hints, in the form of inscriptions that allow you to understand what each of the connectors is responsible for. To connect them, you need to find a special panel on the motherboard ( F— panel) and connect the cables, correctly arranging them.
f-panel
Pins responsible for the front connectors of the system unit
- Power SW responsible for the power button of your personal computer
- Reset SW for the reset button
- Power LED- these are the power indicator cables (lights that light up when the computer is turned on)
- D.D.LED– HDD loading indicator cable
When installing these cables, you must adhere to strict order. Each pin should be connected so that the inscription looks up. The location of their connection is often indicated in the tips near the F-panel on the motherboard itself. However, for convenience, it is recommended to use following scheme.
Connector layout It is also worth paying attention to the fact that the connectors power LED divided into two 1 pin cables and subdivided into "+" and "-". It is necessary to arrange these pins so that as indicated in the diagram.
With the standard F-panel layout, the result should look like this:
Final result However, this process is not over.
Often, on the front panel of the system unit there are also interface connectorsUSB and 3.5mm ports for connecting audio devices and a microphone.
USB and 3.5 mm connectors There are also hints on these cables, and it’s quite hard to make a mistake, because. also present on the motherboard. signatures near the sockets required for connection.
Pins for 3.5mm jacks

How to connect video cards
Before installing this device, you need to determine in which port it should be installed.
Video card connectors are three types:
- Standard AGP(Obsolete and no longer used in modern models)
- Standard PCI(Used by previous generation cards)
- Standard PCI— Express(Used by modern graphics cards)
Because standard AGP already outdated, we will consider only connectors PCI and PCI— Express.
PCI-Express slot
AGP connector
It should be noted that connecting a video card with an AGP connector to a PCI-Express slot and vice versa - impossible. These standards differ not only in size, but also in cutout.
Comparison of AGP and PCI-Express standards Having dealt with the type of port to which you need to connect the video card, you can proceed with the installation.
To get started you will need remove the plug from the back of your system unit. This can be done by unscrewing the fixing screw.
Stubs After the plugs have been removed, you need to carefully insert video card to the port you defined earlier. It is not necessary to apply force to the connection, the card enters the slot very easily, and the latch will help to make sure that it is installed correctly and tightly, which will emit click. Also, when connecting, the interface panel of the video card should go to the back panel of your case - to the place where the plugs were previously.
Installing the video card in the slot After the video card is firmly seated in the slot, and the latch is fully latched, you need to fix its bolts, which remained from the removed plug. It happens like this:
Fixing the video card with bolts Make sure the card is secure and does not stagger in the nest.
After that, you need to swipe to this device power supply.
Video card power connectors
Video card power
The video card power cables are included in the complete set on expensive models. On cheaper, such cables not included. Therefore, you will need to check if there is such a connector on power supply.
Module needed connect to the power socket on the video card. This is done in the same way as connecting the power connectors of the motherboard and CPU.
The connection is made up to the moment clicks latch. The other end of the cable is connected to the power supply.
Connecting a sound card
Installing an internal sound card is very similar to video card connection. The difference is only in ports, to which connect this device.
Connecting a sound card to the wrong port will be difficult and even more likely impossible. The length of the PCI and PCI-Express x1 slots is cardinally different.
It is also necessary to remove plug from the back wall of the system unit, and then carefully insert the sound card into the desired port. Most motherboards do not have a latch on these connectors, so there will be no click when tightly connected.
After the actions taken, fix sound card with the fixing bolt left after the removed cover. It is recommended to make sure that sound card connected securely and does not wobble in the socket.
Additional power supply is not required (except for professional models).
Drive connection
Before installing this device, you must determine the type connections.
The drive must be placed in a specially designated place for it inside the system unit. By default, this is the upper front part of the case.
Connecting a drive with an IDE interface type
After installing the drive inside the case, you need to to plug power cable and data cable to it.
Data loop
Drive power cable
The power cable is connected in the same way as the CPU and video card power connectors.
Plume data must be carefully, without applying force, inserted into the connector on the back of the drive.
Connecting the data cable to the drive The other end of the cable must be connected to one of the channels IDE controller on the board.
Location of IDE controllers - Under the number 1 in the figure is shown IDEcontroller, which can accommodate two devices with jumpers Master and slave.
- Under number 2, the IDE controller may also include two devices. In master mode, this is the Master jumper, and in slave mode, this is Slave.
- Number 3 is the controller floppy drive.
To select the necessary jumper (Master or Slave), you need to inspect the drive case. The position of the jumper is indicated there.
Left fix drive to system unit 4 bolts included.
Connecting a drive with a SATA interface type
Installing a SATA drive (used in modern devices) identical installing an IDE drive. The difference lies in the connector that needs to be connected to the drive and the motherboard.
SATA cable
SATA ports
It is worth noting that the power connector for modern drives is different from the power cable mentioned earlier. Below is a photo of the connection SATA-cable and a new power cable to the drive.
Left - power cable, right - SATA It also happens that the drive has an old power connector, but the SATA interface type is used. Such drives are used very rarely, but they do exist.
All that's left is to fix the drive in the case with 4 bolts and check that it is securely fixed.
