Ok, so i'm having some weird issue here. I play WoW, a lot of it, and sometimes all of the suden my computer simply shuts down, it literally turns off and back on a few seconds later, booting completely normal, as if nothing happened.

I get no blue screens, my thermals are fine (50-55c CPU and GPU 65-70c), CPU is a i7 4790k water cooled with a h80i GT, it is @ stock frequency, didn't find a need to OC yet.

The fun thing is that i cannot emulate this outside of WoW, inside WoW if i enable Vsync, the computer shuts down instantly, if i mess with shadows, either bumping them up or down, the computer shuts down.

Now check this out... i can run furmark and Prime95 simultaniously and nothing... the computer works flawlesly, i get no thermal throttle whatsoever, CPU sits @70c after 8-10 minutes and GPU @75c with fans @45%.

I figured it could be PSU related, but i got no way to test this, i did full memory tests aswell and nothing, it's fine as far as i know. As for the PSU, i use a 650w Thermaltake power supply, now i know it's not a great PSU, but should take care of business.

Any idea what could be hapening here? Halp internets!
 
All of your testing points to a corrupted game install or left over driver remnants that the game still calls for in the game inf file.
Download DDU and install it.
Uninstall your graphics driver.
Reboot into safe mode and run DDU for your video card brand.
Reboot into windows and install the latest driver for your card.

Forgot to add Download driver for video card.

If that does not solve your problem I would reinstall the game.
