I just bought a GTX 960 Mini ATX. Everything works fine until I try to play a game or stress test. It tends to shut down and restart. My build is and older build that I just can't afford to upgrade outside of the video card right now. I had bought a R9 380 but that crashed as well so I returned it and got the 960.

CPU: Intel Core 2 Quad Q6700 4@2.66Ghz
Ram: 8GB GDDR2
GPU: Asus GTX 960 2GB GDDR5
PSU: Logisys PS600XBX 600W.
Hard Drive: 200gb (have other to be installed 750)
