How to connect computer cpu power cord?

Want to know how to connect the computer CPU power cord correctly? In this article, PHP editor Youzi will explain this issue in detail. The computer CPU power cord is an important component that connects the CPU and power supply. Wrong connection may cause the computer to fail to boot or the system to be unstable. Below, we will guide you step by step on how to correctly connect the CPU power cable to ensure that your computer runs stably and reliably.

1. How to connect the cpu cable

1. First, install the power supply into the chassis.

　2. In the power cord, find the 24-pin wire that supplies power to the motherboard.

　3. Find the 24-pin power connector on the motherboard, insert the power cord into the motherboard, and pay attention to the position of the power cord's bayonet.

4. In the power cord, find the 4-port line that supplies power to the motherboard.

　5. On the motherboard, find the interface for CPU power supply and connect the power cord to the motherboard.

　6. Find the hard drive power cord. It is connected to 4 wires and is flat in shape.

　7. Connect the hard disk cable to the power interface of the hard disk, paying attention to the direction of the power cable.

8. Finally, connect another SATA power cable to the power interface of the optical drive.

There are three main places in the computer that can use HDMI interfaces. Among them, the HDMI interfaces of the motherboard and graphics card are used to output HDMI signals, and the HDMI interface that comes with the monitor is the input video signal.

1: Motherboard video output interface (when the processor has a core graphics card, that is, an integrated graphics card):

2: Video output interface of the graphics card:

3: Monitor HDMI input interface on the computer:

3. Where to connect the CPU cable of the power supply

Generally, as long as the interface can be plugged in, it should be connected correctly. The motherboard is powered by the big socket, the biggest one. The processor fan power connector is near the processor. For other power sockets, please refer to the manual, because the interfaces on different motherboards are different.

The most important PC power supply interface is the largest in size. It is also called the 24Pin motherboard power supply interface by convention and is plugged directly into the motherboard. This interface has a total of 2 groups of 12V power supply, 5 groups of 5V power supply and 4 groups of 3.3V power supply. The maximum transmission current of each group of power supply is generally 6A, so the maximum power of the 12V, 5V and 3.3V power supply of the interface is 144W, 150W and 150W respectively. 79.2W.

4. How to connect the cpu power supply cable

Your motherboard is really special, but there is still a way to solve it.

You connect the 4 4 ​​PINs of the power supply to the 8 PINs of the motherboard, and then buy a large 4 PIN to square 4 PIN (for CPU power supply) adapter cable for the remaining 4 PINs.

Although the method you mentioned is also feasible, it is more troublesome to connect, and it is not very safe and will cause excessive current in the 4 pins of the power supply. Use the large 4PIN alone to convert a square 4PIN, so that the power is distributed to other 12V branches of the power supply, which is relatively safer.

5. How to plug in the computer cpu power cord

Answer: 1. How to connect the computer motherboard power cord

Find the widest and longest combination line on the power supply (usually 24 hole), corresponding to the 24-pin slot on the motherboard. There will be a buckle on the line. Align the buckle on the slot and insert it directly. Continue to find the 4-hole CPU power supply cable of the motherboard (2 yellow and 2 black wires. combination), and the 4-pin socket on the motherboard is next to the CPU base, and it is also aligned with the buckle and inserted directly.

2. Computer graphics card power supply connection method

Most graphics cards have only one set of power supply interfaces. Ordinary graphics cards have 4-pin interfaces, and better ones have 6-pin or 8-pin interfaces. Flagship-level Graphics cards can have 14 or 16-pin interfaces. The interface is usually located on the top of the graphics card. According to the number of pins of the power interface of your graphics card, align it with the buckle and plug it in directly.

6. How to connect the CPU wiring

There are two ways to change it. One is to disassemble the inside of the power supply and replace a CPU power supply line. This requires welding skills and is difficult for ordinary people to do well. .

The second is to buy a CPU power supply cable. Cut the CPU power supply cable of the original power supply and connect it to the new one. Just seal the wiring port with tape. You can just buy a CPU power supply module cable to connect it.

7. How to install the cable on the CPU

Installation method: The black one on the left is plugged into the cpu fan interface. The one on the right is probably not needed. If you really need it, you need to plug it into the D port on the power supply. Interface, if there is no D port, just buy a Sata adapter cable and convert it.

The CPU will generate a lot of heat when it is working. If this heat is not dissipated in time, it may cause a crash or burn the CPU. The CPU radiator is used to dissipate heat for the CPU. The radiator plays a decisive role in the stable operation of the CPU. It is very important to choose a good radiator when assembling the computer.

Air-cooled radiator This is the most common type of radiator now, including a cooling fan and a heat sink. The principle is to transfer the heat generated by the CPU to the heat sink, and then take the heat away through the fan. It should be noted that different types and specifications of CPUs use different radiators. For example, AMD CPUs use different radiators than Intel CPUs. Intel 478-pin CPUs use different radiators than Intel 775-pin CPUs. .

8. How to connect the CPU to the power cord

The CPU should not be plugged in backwards. The clip is gone, but it cannot be connected at all if the pins are plugged in backwards. It should be reversed and the fan will not rotate. The CPU should automatically stop working, and then a high temperature alarm will sound.

ЦП не следует подключать задом наперед. Зажим отсутствует, но контакты вообще не могут быть подключены, если они подключены наоборот. Если вентилятор не вращается, ЦП автоматически перестанет работать. и затем прозвучит сигнал тревоги о высокой температуре.

9. Как подключить кабель ЦП компьютера

Продуйте воздухом радиатор и процессор.

Для вентиляторов, которые продаются отдельно на рынке, сторона, на которой вы видите провод — это сторона выхода воздуха.

Вентилятор, который поставляется с радиатором процессора, немного отличается. Сторона с проводами, видимыми на этикетке, является стороной воздухозаборника.

Вентилятор блока питания дует наружу, просто попробуйте, положив руку на заднюю часть корпуса, и вы поймете.

Обычно нет необходимости заменять вентилятор блока питания. Если он сломан, обычно необходимо заменить весь блок питания.

10. Где подключать шнур питания и кабель ЦП

Шнур питания компьютера предназначен для подачи питания переменного тока 220 В на блок питания ATX хоста компьютера. Шнур питания компьютера является важной частью. компьютер. Его функция заключается в подключении источника питания материнской платы и источника питания процессора.

Примечание

Внутренний провод кабеля слишком низкий. При включении питания высоковольтный конденсатор внутри блока питания ATX компьютера также необходимо мгновенно зарядить. момент, ток относительно велик, а максимальный мгновенный ток может достигать 6 Ампер или выше. Если блок питания компьютера ATX не спроектирован с буферной схемой внутри, в этот момент будет проходить больший пусковой ток, который также называется мгновенный всплеск. То есть в этот момент, если шнур питания компьютера изготовлен из некачественных материалов, сопротивление будет относительно высоким, нагрев будет высоким, и провод мгновенно перегорит. (Повреждение находится в середине или определенном месте провода)

11. Как подключить кабель процессора

Как правило, на обычной материнской плате есть только один интерфейс процессора. В этом случае нет проблем с наличием двух слотов ЦП.
