What wires should be plugged into the motherboard when assembling a computer?

When assembling a computer, the motherboard is an important circuit board responsible for connecting the various components of the computer. In order for the motherboard to work properly, power cables, data cables, and other peripheral cables need to be connected. Next, we will introduce in detail the cables that need to be connected to the motherboard, including: power cable (24pin and 4pin/8pin); CPU fan cable; chassis front panel cable; graphics card power cable (if necessary); SATA data cable (for connection Hard drive and optical drive); USB data cable (used to connect to the USB interface on the front panel of the chassis). By reading the following, you will understand the connection method and purpose of each wire, helping you to easily complete the computer assembly.

#What wires should be plugged into the motherboard when assembling a computer?

When you assemble your own computer, the connecting cables (all connecting cables) in the chassis are included with the purchased hardware, and there is no need to purchase additional ones.

1. The connection cable between the motherboard and the chassis is brought with you when you buy the chassis, including the front USB cable, boot, restart, hard disk indicator, power indicator, buzzer, etc.;

2. The data cable of the hard disk is brought with you when you buy the motherboard;

3. The cable connecting the host and the monitor is brought with you when you buy the monitor;

4. Some independent graphics cards require a separate power supply. , and when the interface on the old power supply does not match, an adapter cable is required. This is usually included with the graphics card you buy;

5. The others are all included with the power supply.

Extended information:

Additional accessories that need to be purchased by yourself

1. For bulk CPU, you need to purchase an additional radiator.

2. The graphics card and monitor interface do not match each other, so you need to purchase an additional conversion cable.

3. Chassis fan. (The host usually only comes with 1-2 fans. If there are too many, you need to buy extra by yourself)

How to plug in the computer assembly?

1. First insert the 24PIN in the power supply into the 24PIN slot of the motherboard. This item is the mainboard power supply line: after the motherboard power supply connection number.

2. Then there is the CPU power supply. Look at the motherboard. If it is 8PIN, just combine it and insert it. Generally, the CPU power supply is 4PIN. Insert the 4PIN interface in the power supply into the 4PIN slot near the CPU.

3. Then pay attention to whether your graphics card has a 4PIN interface. Generally, low-end graphics cards do not have it.

How to assemble and plug in the computer?

1.

The front panel connections of the chassis generally include front audio, front USB, power indicator light, hard disk indicator light, power on, and restart.

The wiring diagrams for these connections are generally explained in the motherboard manual.

If not, check that it is written on the motherboard. Pay attention to the position of the pins.

They are basically connected in this way. The HD-LED on the motherboard is the hard disk working indicator light, so just write the thread. There are: H..D.D.LED is plugged in. The SP-LED on the mainboard is the power working indicator light. Just plug in the positive and negative ends of the wire with "P" written on it. If the two indicator lights are plugged in reverse, the positive and negative ends are plugged in. Level, the light will not light up after power on. For the one that does not light up, just change the positive and negative directions.

2.

The RST on the motherboard is the reset button. Write RESET on the wire. Plug in the SW. PW-BN on the motherboard is the power-on button. Plug in the one with POWER SW written on the wire.

3.

SPEAKER is the front buzzer, divided into "+" "-" phase; it can happen with ordinary speakers no matter how they are connected, but it is special here. Since the voltage value of +5V is provided on the "+" phase, we must install it correctly to ensure that the buzzer sounds.

4.

The following is the front audio. The F-AUDIO on the motherboard is the location of the front audio interface. It is different from the USB. USB has one less pin on the side. There is one less pin on the 4th pin for audio, just plug it into the corresponding position

5.

The front panel connection is completed, and finally connect the power supply and hard disk. The SATA data cable is in the shape of an inverted 7-digit line. Don’t worry about plugging it in wrongly. If you plug it in wrongly, it won’t go in. The hard drive movie cable is wider than the data cable and has a similar shape. Connect it to the hard drive

6 .

Just align it and insert it. The other end of the SATA data cable is plugged into the SATA interface of the motherboard. That's it, now connect the power supply to the motherboard.

7.

The motherboard is powered by 24P. The old motherboard used to be 20P, so I took it out and there are 4 active ones on the side.

8.

The CPU has 8P power supply, and there are also 4P power supply. Both the motherboard and CPU power supply are designed to be fool-proof. Don’t worry about plugging it in wrongly. If you plug it in the wrong direction, you won’t be able to plug it in.

9.

Connect to the corresponding interface. Look at the motherboard interface diagram above. The graphics card power supply is 6P, and there are also 8P. It can be disassembled, and the graphics card power interface is plugged in. That's it.

10.

The installation is complete. If your case is side-transparent, you can install a strip of polarizing light, which will look much better. If it is not side-transparent, there is no need to install it. You are good to go. For a chassis with back-line cables, put the cables at the back so it looks nice. After installation, untie the cables and tie up the ones that need to be tied up with zip ties to make it look more comfortable.
