I was just playing some WoW, and then my pc shutsdown and reboot, i dont know if my settings are to extreme for a GTX 780 and I5 4760k. My Fans dosent spin like crazy or anything. It just shutsdown. Normal graphics,
My CPU temperature was 58 Celsius and my GPU 38 celsius, so its not a heating problem. I just want to know what make it chras, it has 3 times now.
I suspect my Power Supply but i dont know 100%, pls let me know if you know why.

GTX 780 OC (Downclocked to 902 on GPU boost clock and 6008 on memory clock)
I5 4760k not overclocked
Z97-K
Windows 7 64-bit
RM 850 PSU
4 GB ram
