3. Computer power cord sequence?

Let’s first take a look at the power interfaces included with the power supply: ATX 24-pin, ESP/ATX 12v 8p, PCI 6p, 4p, SATA, and floppy connectors;

Insert the ATX 24p into the motherboard and the processor power supply interface into the processor The device interface is EPS/ATX.

Next, plug the SATA power cable into the hard drive to power the hard drive.

If you have a graphics card, plug the PCI power supply interface into the graphics card! The power connection is complete!

4. Modification of the computer power cord?

The power cord of the computer cannot be modified casually. The power cord of the computer is actually fixed. During the process of modification, you will find that even if you complete the modification of the entire computer, there are certain risks. During use, this risk will appear after you start using it, and there is a chance that it will be triggered. The entire power supply catches fire and burns because after you modify and seal the power cord, the entire power supply is in a chaotic working mode.

5. Desktop computer power cord?

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)

6. What is the power of the computer power cord?

The power cord generally withstands a maximum current of 10a, so the power should be 2200w

Desktop computer host power supply generally requires a rated power of 200W or above. Computer power supply is a device that converts 220V AC power into DC power and specifically supplies power to computer accessories such as motherboards, drives, graphics cards, etc. It is the hub of power supply for various computer components and an important part of the computer.

7. What is the material of the computer power cord?

There are 5 main materials for computer power cords, namely conductor materials: copper, aluminum, silver, gold, etc.; insulation materials: PE, NR, neoprene, nitrile rubber, cable paper, paint; sheath materials: Polyethylene, nylon, etc.; semi-conductive materials: silicon, germanium, etc.; barrier materials: copper wire, copper strip, aluminum strip, etc.

As PC hardware specifications gradually increase, its power consumption is also increasing, and a small resistance reflected on the power output line will produce a large voltage loss. At this time, if the corresponding hardware consumes a large amount of power , and the poor quality of the power supply output line is likely to cause excessive load, causing the line to overheat or even burn out. Thin wires often age due to overheating after being used for a long time, and the rubber wrapping the metal wires can easily break and cause safety accidents. Therefore, you should choose a power supply with thicker power cords and better materials.

8. Classification of computer power cords?

Classification of computer power cords:

1. Yellow wiring

Yellow wiring is the most common wire inside the computer. They are generally connected to hardware devices such as CPU and PCI-E graphics card. Therefore, the yellow wiring Voltage supply is very important. According to relevant standards, the rated voltage requirement of the yellow wiring is approximately 12V. The fluctuation range is between 11.40-+12.60.

2. Blue wiring

The blue power cord is mainly used for logic judgment devices. Therefore, it does not require a large current to work normally, and it also has a relatively high voltage fluctuation range requirement. wide, the general rated voltage standard is 12V.

3. Red wire

The red wire is very similar to the yellow wire. It is also one of the most important power wires inside the computer. The red wire is mainly provided to the cores of the CPU and integrated circuits such as PCI, AGP, and ISA. The voltage of the devices and the wiring that ensures their normal operation are generally rated at 5V, with a fluctuation range of +4.75-+5.25.

4. Wiring

White wiring is a relatively rare type of power cord on the market, but some computers still have a lot of them inside. The white power cord is mainly provided for logic devices to determine whether the level is high or low. , the rated voltage standard is 5V, and the fluctuation range is large.

5. Orange wiring

The orange power cord is also very important. It is specially used to provide power to the memory. The orange power cord is directly related to whether the memory can operate normally. The rated voltage standard of the orange power cord is 3.3V, the fluctuation range is +3.14-+3.45V.

6. Purple wiring

The purple power cord is very important. When it is powered on, it will provide power to the motherboard through PIN9, which directly affects the operation of the entire computer. It is also connected to the boot circuit and USB interface. If Even if the purple wiring is faulty, the computer cannot be turned on normally. In addition, the purple power cord also directly affects the power supply performance and efficiency of the power supply. It is a group of lines that affects the energy consumption of our computers. Its rated voltage standard is 5V, with a fluctuation range of +4.75-+5.25V.

7. Green wiring

The main function of the green power cord is to control whether the power button is on or off by controlling the level status. If the relevant level of the purple power line port exceeds 1.8V, the main power display status is off; conversely, if the relevant level is less than 1.8V, the main power display status is on. Therefore, there is no relevant standard for the rated voltage of green wiring, and there is no limit to the fluctuation range.
