Random shutdown problem - Corsair Builder Series CX430W ?
Hi all!
My system started having random shutdowns recently. I suspect it's the PSU but I really don't know how to evaluate it.
The symptoms: Under heavy load (playing Dragon Age for about an hour or a bit more) the PC just shuts down. No BSOD, no error message, nothing, it just shuts down. I can't turn it back on right after that, only after waiting a couple of minutes and/or switching the PSU on and off (I'm not really sure which of these solves the problem). Such problem never occured under normal load so far.
I know that CX430 has multiple different voltage protections built in, I'm just not sure which one gets triggered - to be honest I'm not even sure if it's the PSU, but the fact that I can't turn it back on immediately afterwards suggests some sort of circuit breaking mechanism behind it.
Any suggestions? How could I confirm that it's the PSU? What else can be the cause?
