My computer shuts off approximately 30-45 minutes into a game and will not restart for 15 minutes. So far I have updated all my drivers, cleaned registry, run Memtest 86 (no errors), Prime 95 (runs like a champ).

Eventlogs have no record of any precrash problems, and nothing useful afterwards. I've sorted through them quite thoroughly and they are completely useless.

I took my PC to a friends house and we swapped GPU's, he has a 5900 Series card that uses 2x 6 pin connectors, mine uses a 6 pin and an 8 pin. His computer never crashed while running with my GPU, and mine never crashed while running with his GPU (which does use less power).

We stress tested the PC and determined that the CPU, GPU, and hard drives are not overheating.

The PSU passes when plugged into a multimeter, but I don't know if it is having problems under load.

I've even gone so far as to change out my surge protector and move to another socket just to make sure it wasn't either of those causing the problem.

I'm thinking the problem is my PSU either over heating or failing under load, shutting down and then making me wait to restart it while it cools off/resets, but I really don't know. I submitted an RMA to Cooler Master and it has been approved, I'll be sending the PSU back in a few days.

Given the information I have provided, is there anything I might be missing or haven't done that could reveal the problem?

The PSU itself? If the fan is not running, don't use the PSU. It is obviously defective. Contact the retailer if still RMA-able, or the manufacturer for an RMA. The only thing keeping the PSU from burning up (and starting a fire) is the thermal overload device.

Some high end PSUs' fans only run when the temp gets to a certain point. I don't see that disclaimer listed on yours, though. It just states that it has a variable speed fan. If the fan died, or the fan controller in the PSU died, that would explain your problem.

Sounds like now you just sit and wait.
When I get a bad component, I usually send it back for refund rather than replacement, and then order the new part right away. That saves on turn around time. If finances allow, you might want to do that so you get the new PSU sooner.
