You and I have a fairly similar system so you probably know what's going on with mine.
Thanks for the advice for what was wrong with the PSU. Unfortunately it was nothing to do with the hardware unless you count my brain as malfunctioning

.
Plugged the 6-pin connector for the video card into the 6-pin auxilary on the PSU instead of the 6-pin PCI-E. Pretty stupid of me

.
Now if I can just get the CPU temp down I'll get into some overclocking. I've ordered a thermalright bolt-thru kit to get rid of this push pin design so hopefully in a few days I'll be able to give some positive updates.
