PSU Loud Pop

chroniclard · 5 Dec 2018 at 14:28

Just built up another rig and when I turned the PSU switch on there was a loud pop, immediately turned it off then tried it again. The fans still spin up and the motherboard led's all light up. (Doesnt actually produce a display or boot yet, that may be a separate issue).

Could a loud pop be anything but bad?

Funnily enough it is a Corsair. Will have a bit more of a google, thanks.

It should not be popping/banging and/or sparking at all. That said the PC appeared to work fine when it was on......

Not sure if its safe or not but I dont like it so have started the RMA process. Using an old spare 750w for now which doesnt bang when you turn it on.

Same, worked but kept popping/sparking, cant be doing with that. Got an RMA number for it, will go back soon as I can post it.

Decent enough PSU's, just appears there is some kind of design fault!
