Need a 2nd opinion on a problem I'm having with crashing during gaming

Hi everyone! I had a pretty nice build, but was having to many issues with it shutting off during gaming. So I got sick of it and decided Id just build a new system (will post specs at bottom). I replaced everything except for the power supply. The PSU is a Coolermaster 1000w so i didnt think that would need replaced. Well anyways I've only been able to try Far Cry 3 out on the new system. I have it set on ultra and it runs smooth as butter. But between I'd say 30 mins and an hour my computer just shuts off and reboots. Right when it turns itself back on the fan inside the PSU begins spinning at maximum rpm and doesnt stop until about 5 minutes after the computer has been on (It's very loud). All my temps are good on my cpu, gpu, etc. My guess is either the PSU is clogged up with dust and overheating or I just need to buy a new one. Anyone agree with me or have another suggesting as to what could be causing this? Thank you everyone for your time and responses.

Specs: Intel I7 3930k @stock speeds (water cooled)
16gb G-Skill ram @ 2400mhz
Asus rampage IV formula
Geforce GTX 780
Coolermaster 1000w psu

So you believe more than likely It's just my PSU crapping out?
