Brand new PSU worked for 1 hour then shut down and wont start back up

[thebigcores]

So after a hardware failure on my last PSU i bought a new one (EVGA supernova 650 G2). I removed my old one along with all the sata/power cables and installed the new one. Everything worked fine for about an hour until it just randomly shuts down. I try to boot it back up and all i get is about half a second of power then it stops. I've tried taking all of the pins out and putting them back in again making sure they are secure and switched the plug incase there was a fault with that. Had no luck and honestly have no idea what to do. I just tried the psu tester kit provided with the PSU and the same thing happens, fan just spins for half a second then stops.

Any help would be much appreciated. Specs are here: https://pastebin.com/MzLenPAC

I'll be going to bed now as its midnight so i'll respond to any replies in the morning.

Try RMA-ing it, since under warranty.
