So i bought an NZXT hale82 650w psu to power my rig. NZXT HALE82 HALE82-650-M 650W ATX12V / EPS12V SLI ... i5-3570k gigabyte z77-ud3 palit gtx 680 jetstream 2gb 2x4gb generic ram 250gb hdd I was able to get it running for an hour to install windows and other programs. Turned it off and called it a night. Next morning, the unit won't turn on. Even the psu's fan isn't spinning. Is the problem with the psu or could it have been caused by something else? Thanks!
