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.
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.

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)
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.
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.
1 USB is a set of 8-wire 10-hole plugs. The side with the black wire should be inserted in the direction of one less pin on the motherboard. 2 RST pins are connected to the panel reset button. PO-ON pins. Connect the panel power-on button (no requirement if plugged in)
3 HD-LED is the hard disk read and write indicator light (note that if the positive and negative poles are plugged in, if they don’t light up, just reverse them)
4 PWR-LED is the host power indicator light·(Note that if the positive and negative poles are plugged in, if they do not light up, just reverse them.) 5 SPEAKER is the buzzer pin. The black wire is negative and the red wire is positive·6 Panel headset· The motherboard pins are a row of 10-pin double-row pins. The second pin in one row is missing one pin. It is actually 9 pins. The panel connection plug is a set of 5-wire or 7-wire 10-hole plugs, one or two of which are Empty·(no wires), just insert it in the direction with one less pin on the motherboard··

5. Separate the front USB and audio jack cables with USB and AUDIO letters on the back from the chassis, and insert them into the USB pin slot and AUDIO pin slot of the motherboard respectively. Both are to prevent mis-insertion. The USB pin slot is usually in the lower right corner of the motherboard, and there is a USB mark under the pin slot. The AUDIO pin slot is generally located in the middle and lower left side of the motherboard.
6. Knot the switch, restart, hard disk indicator light and other wires on the chassis. Generally, this type of plug on the motherboard is adjacent to the USB. In the lower right corner of the motherboard, there are letters marking the corresponding plugs on the motherboard, such as HDLED. is the hard disk indicator light, RST is the cold start, POW-SW is the startup, SPEAKER is the alarm horn, and POW-LED is the power indicator light. Just plug them in one by one.
7. Remove the baffle at the optical drive position of the chassis (the card head can be pushed out from the back and removed). Put the optical drive in and secure it with screws.
8. Take out the optical drive and hard disk data cable. If it is a parallel port data cable, please confirm that there is an IDE interface on the motherboard. The serial port cable is generally longer. After forming a spiral shape with your fingers, you can insert it into the motherboard serial port port in sequence, and then plug in the optical drive and hard disk power cables.
9. Use tying thread to gather and fix the messy threads appropriately. Install the side covers in sequence. You're done, the next step is to partition the hard drive and create a system.

The method of plugging the computer's cable into the motherboard depends on the type of cable you want to connect. Here are some common cable types and how to plug them in:
1. Power cable: The power cable is the cable that connects the power supply to the motherboard. It usually has a 20-pin or 24-pin connector. Plug the power cord into the power socket on the motherboard, making sure the connector is oriented correctly, and then gently press the connector until it is fully inserted.
2. Data cable: The data cable is a cable that connects hard drives, optical drives and other devices to the motherboard. It usually has a SATA or IDE interface. Insert the data cable into the corresponding port on the motherboard, making sure the connector is oriented correctly, and then gently press the connector until it is fully inserted.
3. USB cable: A USB cable is a cable that connects a USB device to the motherboard. It usually has a USB interface. Insert the USB cable into the USB port on the motherboard, making sure the connector is oriented correctly, then gently press the connector until it is fully inserted.
4. Monitor cable: The monitor cable is the cable that connects the monitor and the motherboard. It usually has a VGA, DVI or HDMI interface. Plug the monitor cable into the corresponding connector on the motherboard, making sure the connector is oriented correctly, and then gently press the connector until it is fully inserted.
It should be noted that before plugging in the cable, you should turn off the computer and unplug the power plug to avoid electric shock and damage to the equipment. In addition, be careful when inserting the cable to avoid damaging the connector due to excessive force.

The method of plugging the motherboard power-on cable is: Plug the power-on cable into the switch jack on the motherboard, usually near the power jack. When inserting, pay attention to the front and back of the jack. Generally, a black interface is inserted into a black one. Jack, the red interface is inserted into the red jack. After confirming that the insertion is correct, turn the switch to the "on" position to turn on the phone.
1. First, connect the power cord from the chassis. One of them is relatively wide. If it is marked USB, then it is the cable connecting the USB socket on the chassis panel. On the motherboard On the edge, look for the USB pin and plug it in.
2. In the wiring harness in the chassis, if you see a wire marked HDD_LED, then this is the wire for the disk’s working indicator light, which is consistent with the corresponding HDD_LED pin on the motherboard. Just pick it up.
3. When you see a line marked Power_SW, connect it to PWR_BTN. The position of PWR_BTN on the motherboard and HDD_LED are marked in upper and lower rows. Some are marked PWR_SW, but they all refer to the host power switch line; POWER_LED is the indicator light, just connect it to PWR_LED.
4. In addition to these, there is also a more important motherboard wiring in the host, which is the restart switch line. This line is marked RESET_SW on the head.
5. On the motherboard, find the pin marked RESET. Because it is marked in rows, it is the two pins in the lower row. Just plug it in.
