The voltage is unstable, the computer is easy to crash, how to get it without a voltage regulator

Symptoms of unstable computer power supply voltage include unstable system and blue screen.

Freeze, stuck, slow, auto shutdown, auto restart, etc. The specific analysis is as follows: 1. Cause greater damage to the power supply of the host:

The computer works in an unstable and low voltage state for a long time, and the components in the host power supply age very quickly, resulting in the unstable output voltage of the host power supply and damaging other parts in the computer. 2. Cause greater damage to the hard disk: The computer works in an unstable and low voltage state for a long time, and the hard disk will rub the magnetic head against the disc due to the insufficient power of the motor, which will gradually cause physical damage to the track.

If the hard disk suddenly loses power, the damage to the hard disk is also great, just like driving a car that often brakes suddenly. 3. It is easy to cause damage to the power supply part of the motherboard: when the voltage is unstable and the voltage is low and the computer is restarted, it will have a great impact on the capacitors and chips of the motherboard.

The voltage is unstable, the voltage is low, and the computer restarts frequently, which is very harmful to the computer. It is recommended not to use the computer temporarily during the period when the voltage is unstable and the voltage is low. This answer applies to most computer models such as the Dell G15.

There are two main reasons why the output voltage of the computer switching power supply is unstable

1. There are problems with the components around the chip of the voltage regulator circuit, especially the voltage regulator reference element;

2. Instability caused by fluctuation of +5V output circuit. When there is no load, the +5V rectification, filtering and output transformer should be checked.

The protection function of the computer power supply is very perfect, with over-voltage protection, over-current protection, and short-circuit protection functions. This data is fed back to the control chip. When the protection circuit components are unstable, the output voltage of the power supply will also be unstable.

The hazards of unstable voltage of computer power supply:

2. The damage to the hard disk is greater, and the voltage is unstable, which will lead to insufficient power of the hard disk motor and cause damage to the track, and sudden power failure will also lead to damage to the hard disk;

3. Unstable voltage will lead to a large impact on the capacitors and chips on the motherboard, which will also lead to damage to the components in the long run;

4. If the voltage is unstable or too low, the computer will restart, and the system files will be lost after the restart, resulting in the inability to use normally;

5. If it is a miscellaneous computer, it will cause the computer to burn out directly;

6. Low voltage will cause bad sectors in the hard disk, and then there will be problems such as loss of saved files and slow system operation.

Whether it is a desktop or a notebook, the impact of voltage instability is very large, and the phenomenon of voltage instability often leads to damage to the hardware of the computer and affects the user experience. The direct impact is on the hard disk of the computer, followed by the power supply part (including the power supply part on the motherboard). Excessive voltage, especially in the case of instantaneous high voltage, may also damage the CPU and memory modules.

Even hard drives, etc.

Voltage that is too low or unstable will cause the computer to restart, and the computer hardware will restart.

The most easily damaged is the hard disk, a hard disk is often used in the case of abnormal shutdown, the life will be quite short, this damage to the hard disk is a physical damage, important data recovery is quite difficult, so it is important to pay attention.

When the number of devices in the system increases, the power consumption increases, and the output voltage of the inferior power supply will decrease sharply, which eventually leads to the instability of the system and the phenomenon of automatic restart.

If the voltage is unstable, use a wide range power supply.

For example, the Xianma Gold Medal 500W supports 100-240V AC input.
