There are three main places in a computer that can use HDMI interfaces. The HDMI interfaces of the motherboard and graphics card are used to output HDMI signals, while the HDMI interface of the monitor is used to input video signals.

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

2: Video output interface of the graphics card:

3: HDMI input interface on the monitor:

3. Power supply Where to connect the CPU cable

Generally, as long as the interface can be plugged in, it should be connected correctly. The motherboard supplies power to the big socket, the largest 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 customarily called the 24Pin motherboard power supply interface, which is directly plugged into the motherboard. This interface has a total of 2 groups of +12V power supplies, 5 groups of +5V power supplies and 4 groups of +3.3V power supplies. The maximum transmission current of each group of power supplies is generally 6A, so the maximum power of the +12V, +5V and +3.3V power supplies of the interface They are 144W, 150W and 79.2W respectively.

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 connection 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 to plug in the D port on the power supply, buy a Sata adapter cable if there is no D port. Just one click.

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. If the fan does not rotate, the CPU will automatically stop working, and then it will High temperature alarm.

Blow air to the heat sink and CPU.

For fans sold separately on the market, the side where you see the wires is the air outlet.

The fan that comes with the CPU radiator is a little different. The side with the wires visible on the label is the air intake side.

The power supply fan blows outward, and you will know by trying it with your hand on the back of the case.

You generally don’t need to replace the power supply fan yourself. If it breaks, you usually need to replace the entire power supply.

10. Where to connect the power cord and CPU cable

The computer power cord refers to inputting 220v AC power to the computer host atx power supply. The computer power cord is an essential part of the computer. Its function is to connect the motherboard power supply and CPU power supply.

Notes

The internal wire of the cable is too inferior. When the power is turned on, the high-voltage capacitor inside the computer ATX power supply also needs to be charged instantly. The current is relatively large at this moment, and the maximum instantaneous current can reach more than 6 amps. If the computer ATX power supply is internal If a buffer circuit is not designed, a larger inrush current will pass through at this moment, also called an instantaneous surge. That is to say, at that moment, if the computer power cord is made of inferior materials, its resistance will be relatively high and the heat will be high, and a wire will burn out in an instant. (The damage is in the middle or a certain position of the wire)
