Power supply popped

[Dmart]

My power supply popped when plugging it into the wall. What's the chance my PC is dead?

Hello,

 

Was the PC booting when it popped ?

Could just be the capacitors charging up. That would be the case if the PSU is brand new, or had not been plugged in for a while.

Some power supplies have a circuit inside which includes a relay, which makes a mechanical click when it's activated.

 

The reason for that circuit is to slow down the "initialization" of the power supply. When a power supply is plugged in, it "sucks" a lot of energy from your wall socket for a few milliseconds and that can make the electrical panel think something is wrong and trip the fuse in your electrical panel, disconnecting the power from your room's outlets.

 

So there's a circuit inside the psu which is like a break, making the psu take more than a few milliseconds to start up when plugged in and after that period of time that mechanical relay activates and removes that "break" circuit which would otherwise make the power supply less efficient.

 

Without that break circuit, if the power supply has no such circuit, you may even see sparks when plugging or removing the power supply cable from the mains outlet. Even without the circuit, depending on humidity in your room and other factors, you could have sparks when plugging or unplugging the psu. Such sparks can produce noises similar to pops.

I'm sorry when I said I plugged it into the wall I mean I plugged the female end into the PSU and saw a flash of light and heard a pop

sounds like it's just a small arc, it happens, you should be fine

if it doesn't power on then come back and we'll go from there

The power isn't community back on

be sure to RMA the old psu or get a refund if you can, most of them have great warranties
