What are the consequences of insufficient power supply to the motherboard?

What happens if the motherboard power supply is insufficient?

The power of the power supply is not enough to support the startup of the host: there is no response at startup and the light will not light up at all. There is another manifestation of the fault, that is, sometimes it can be turned on normally, sometimes it cannot, and sometimes it has to press the power switch several times. to boot.

2. Insufficient power, instability, frequent restarts, and failure to enter the system. One or several IDE/SATA storage devices cannot pass the startup self-test when booting, and stay on the motherboard information screen.

3. It crashes when entering the system and restarts frequently during use.

4. Insufficient power supply to the graphics card slot of the motherboard causes a frozen screen. If the power supply of the graphics card slot is seriously insufficient, the host will not be able to turn on at all or will alarm when it is turned on.

5. Insufficient power supply to the memory slot and memory. In the long run, there is a risk of burning the motherboard and memory.

What should I do if the motherboard power supply is insufficient?

Solution to insufficient power supply of the motherboard:

To determine whether it is a power problem, first unplug all the cables connected to the motherboard.

Find a paper clip.

Find a set of 24-pin (some are 20-pin) cables on the power supply, and find the green wire and the black wire. There is only one green wire. There are several black wires. Choose one close to the green wire. Any of the black ones next to it can be used!

Insert one end of the U-shaped paper clip into the green hole, and the other end into any black wire hole next to the green wire.

After inserting the paper clip, you can now connect the power cord and start powering on.

Why is the motherboard’s power supply insufficient?

The so-called insufficient power supply comes from two aspects. The first is your computer power supply. Nowadays, computer configurations are getting higher and higher, and power consumption is increasing. If the computer power supply is insufficient, it will cause frequent restarts. , or a crash occurs. As for the insufficient power supply of the motherboard, it is a design problem of the motherboard type. There are many capacitors and coils near the CPU socket, which are used to power various accessories on the motherboard. If the capacitor capacity is very small, or the motherboard cuts corners, it will also cause the computer to malfunction. An unstable situation occurs.

Insufficient power supply to the motherboard?

1. The power of the power supply is not enough to support the startup performance of the host: there is no response at startup and the light cannot light up at all. There is another manifestation of the fault, that is, sometimes it can be started normally, and sometimes it cannot, and sometimes it has to press a few times. Turn on the power switch.

Solution: According to the power consumption of the host, choose a brand power supply with higher power.

　2. Insufficient power, instability, frequent restarts, and inability to enter the system. One or several IDE/SATA storage devices cannot pass the startup self-test when booting, and stay on the motherboard information screen.

Solution: The temporary solution is to reduce the number of storage devices. For hard drives and optical drives that are not commonly used, it is best to unplug their power cords and data cables. The fundamental solution is of course to replace them with a more powerful one. power supply.

　3. Does it crash when entering the system or restart frequently during use?

　4. Insufficient power supply to the motherboard’s graphics card slot causes a crash screen. If the power supply of the graphics card slot is seriously insufficient, the host will not be able to turn on at all or will alarm when it is turned on.

　5. Insufficient power supply to the memory slot and memory. In the long run, there is a risk of burning the motherboard and memory.
