Why is my power supply blown?

However, in some other designs of power supplies, the power section components seem to be easily blown when there is a short circuit either in the secondary side or the load. 4) Bad corresponding components- For example, if the power FET is shorted, most of the time the power IC could be shorted too.

Why does my computer keep blowing power supplies?

They can be expensive though. If your computer keeps blowing power supplies, spend $20-30 on a good quality surge protector and I suspect your computer will no longer go through so many of them. The other main reason a computer keeps blowing power supplies is overheating. In this case, you’re likely not blowing the power supply at all.

How do you know if a power supply has burned out?

The standard way to tell if you have burnt out any of your existing hardware is to try it with a replacement power supply. It is very possible that you have damaged one or more of your existing components, but you might be lucky and your old power supply may have failed in a way that left everything else intact.

What causes a power supply to fail?

3. Power components Power switching components, or MOSFETS, which take the brunt force of operation of the power supply, can sometimes cause failure if the heat sinking is inadequate, or if the drain overvoltage, drain overcurrent, gate overvoltage, or the internal antiparallel diode is overstressed.

How does a computer power supply work?

The power supply in a desktop computer has a lot of responsibility. It has to take electricity from the wall and refine it to remove spikes, divide it into much smaller voltages and then deliver all those voltages to the many components within a PC.

What causes high currents in power supplies?

Those high currents are also called "inrush currents," and in power supplies, the main reason for them is the charge of the bulk cap (s). High voltage and current surges can be the cause of multiple component failures, including fuses, bridge rectifiers, diodes, and FETs.
