The computer burns six power supplies in a month, and the computer power supply burns out two in a m

Hello. You've taken into account one thing, the power supply is over the maximum load. But if you burn 6, then you won't burn them all, not to mention that the power supply also has overload protection.

First: calculate the power of the host when it is fully loaded, and then match it with a matching power supply.

Second: check the motherboard. Based on what you said, the motherboard is more likely to cause it. The problems caused by the power supply are smaller. It mainly depends on whether the capacitor is burst, whether it is caused by leakage and other conditions.

Third: If you don't know much, or ask someone else to change 6 power supplies, then the maintenance person doesn't know much either, doesn't solve the fundamental problem, or you don't explain the situation. This time you have to explain the situation and solve the fundamental problem.

Fourth: Caused by voltage instability, most likely. Check whether the voltage in your home is stable, or the most intuitive way to judge is to see if the lights in your home are on and off.

Is there a problem with the socket you're using, or the power cord isn't plugged in tightly, or the fan speed is low.

I have been engaged in power installation for many years, but I have little research on computers, if the system often burns the power supply, the voltage of your home should be the biggest problem, if it is three-phase electricity. Occasionally, there may be a loss of phase. You should call the electrician to check the voltage.

See where the power cord is short-circuited, or is consuming power, you turn off the computer, but the power fan is kept rotating, specifically find someone to show you, it should not be caused by any audio, printer.

burned six power supplies in a row, how can you have a strong word, admire

This situation is special, and the common causes and solutions are as follows:

1. The mains power is unstable, causing the power supply to fluctuate too much, so you can buy a home voltage regulator and connect it in front of the computer power supply.

2. The power of the computer power supply is not enough, just buy a power supply with more power.

3. If the computer hardware is faulty, overhaul the computer thoroughly and eliminate the faulty original.

4. If there is poor contact between the power supply and the mains power supply or the family is instructed to dig and fire, ensure that the contact with the mains meganucleus is good.

5. The computer does not dissipate well, resulting in high temperature burning out the power supply, so let the computer be well ventilated.

The power supply is used for a rough and long time, and the dust is not maintained and cleaned, etc., and leakage and static electricity can lead to the burning out of components.

The voltage is unstable, especially when the voltage is too high, this phenomenon is relatively rare in brand power supplies, because the adaptation of high-quality brand power supplies is relatively wide. Inferior power supply is easy to burn.

The power supply is rated for insufficient output power and is overloaded. The component is severely heated and damaged.

The use of inferior miscellaneous power supply, the quality of the components itself is poor, the power is false, and the burnout rate is very high.

Bugs and other insects enter the inside of the power supply, causing a short circuit and burning out the components.

The power plug and socket are not in good contact with the rock traces, and the spike pulse current will instantaneously break down the weak components with low withstand voltage.

The power supply is generally burned out for the following reasons.

1. The mains voltage is unstable, and the working range of the computer voltage is generally between AC 180V-240V, and the voltage is too low and too high to burn the power supply. Find the municipal power department to deal with it so that it can supply power normally; Buy a wide power supply, or another voltage regulator with an input voltage of 150-260V and 500W.

Second, the rated output power of the power supply is insufficient, the load is overloaded, overloaded and burned out, buy a power supply with high power.

3. The power supply is burned out due to a slight short circuit or intermittent short circuit in the host circuit. Focus on checking the installation of the motherboard board to avoid the failure caused by the short circuit between the board cards or between the board and the chassis caused by improper installation; When used for a long time, oxidation and performance changes will cause the instability of the overall circuit work, which will lead to damage; Worms and the like enter the main machine, resulting in a short circuit and burning out the components; In addition, the power plug and socket are not in good contact, and the spike pulse current can instantly break through the weak components with low withstand voltage.

Fourth, the quality of the power supply itself is poor, and the failure of the power supply fan is the main reason for the power supply to burn out. Clean the dust on the fan blades in time and oil the bearings.
