Psu unknown fault

[KingSimcock]

My psu is a powercool x-viper modular 850w 80+ bronze. And when I was building the pc before I had an ssd or hdd it would power up the system with no problems. But when I plugged in the ssd and hdd then installed windows I started to have problems. It just keeps switching off. Most of the time after the beep on boot up. Sometimes after several hours. And when it does switch of I cannot restart the system without unplugging the power and waiting a bit. What is going on here? And this is a second hand psu so I can't take it back for a replacement.

God damn it. Well I paid £50 for the psu, mobo, processor, graphics and ram. So not a huge loss but luckily I have a spare 200w for now that is holding solid so far.

Didn't know there was a signature limit but I have briefly shortened it. But I can't see it on my mobile.

Have you tried connecting the SDD on a different power cable and see if the problem persists?

Yes that was tried with different combinations of cables but nothing worked. I have recently bought a new psu and that is working great. I still have the old one incase I can fix it one day. I'm forever the optimist.
