Psu problem? or something else?

[warband_13245]

So i bought an NZXT hale82 650w psu to power my rig.

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?

ONLY TRY THE FOLLOWING IF YOU HAVE ASSEMBLED THE COMPUTER YOURSELF.

1)Open your cabinet, remove the power on connector pins (connected to motherboard power button) from motherboard & short the PWR_ON pins on motherboard with a screwdriver to see if it starts up.

If no luck then
2)Check your SMPS: http://www.pcpower.com/support/ATX_troubleshoot.htm
