Hello everyone... I decided to ask the community about a problem I have. Hope you guys can help!

I just upgraded my PSU and Video Card, from an Agiler 800W and EVGA GTX 660 to a Corsair CX600 and Sapphire R9 270X.

Problem is that, PC turns on normally; but after 1-2 minutes, the R9 270X stops sending signal to my monitor without a reason! Even in safe mode, and even when accesing to BIOS it simply stops sending signal!

I tried the card with my old PSU, and it's the same. After a couple of minutes it stops working. I tried the new PSU with my old VC (GTX 660) and it worked normally.

Is it possible the R9 270X is faulty?

My Specs:

i7 3770 -Stock Clock-
Mobo Intel DH77EB.
Corsair HYDRO H80.
PSU Corsair CX600 600W.
Sapphire R9 270X Dual-X 2GB.
Win 8.1

Thanks a lot everyone for taking your time in answering this! Much appreciated!
