I have built my pc for 3 weeks ago, and i had a GTX 780 installed. When i was playing games my pc chrased. My PC crashed 1 or 2 times a day. So i decided to swap my GTX 780 out with an XFX HD 7770 Core edition. And it has been 4 days now, since i swapped my GPU, my pc has been solid as rock since i swapped.
I dont know if there is a internal error in my GTX 780 or my RM 850 PSU doesnt give enough power for my GTX.
So my question is: Could it be an internal error with GTX780?
Or does my Power Supply doesnt give enough power?

Please note, that my GTX 780 never goes over 70 celsius, My CPU is running at 66-69 Celsius, My XFX HD 7770 is constant on 50 celsius

Specs:
Windows 7 64-bit home premium
Z97-K motherboard
i5 4760k
RM 850 PSU
GTX 780 Direct CU II OC(Swapped with my old/new XFX HD 7770)
1,5 tb seagate harddisc
4 gb ram

Im gonna try if i can get my GTX 780 sent to repair this week, but i got Watch Dogs when i bought the GTX 780, and i have used the key, so i cant get my money back with paying for Watch Dogs. :( Hope they can repair it.
