My computer is shutting itself down and I don't know why.

So recently my desktop computer has been shutting itself down completely and instantly with no warning and no blue screen. This is only happening when I am playing certain games. For example I can play Overwatch with no problem with one exception. I have played WoW with no problem with one exception as well. Recently though I started playing the game Tales of Berseria and my computer has shut down multiple times while playing it. I mention the games since this started happening with this game constantly. Today I ran multiple stress test thinking it could possibly be an overheating problem or a PSU problem. I also have been logging my core temp. with the program core temp. I used the Unigine Vally benchmark to test the GPU and Prime95 to test heat and power usage. For the prime 95 I ran an In-place FFTs which says it puts strain on the power supply and ran it for 30 minutes with no problems. The temperatures during this sat around 60 degrees C. I then tried the game with the log still running and in 10 minutes my computer shut off. The logs showed my temperature was sitting at around 60 degrees C when it shut down. I am unsure what the problem could be that causes it to only crash on certain games for the most part.

My Computer specs are
Intel i5 2500K
Nvidia GeForce GTX 780
Corsair HX 750
Cosair Vengance 8GB 1600MHz
Windows 10 64-bit

have latest Direct X installed?

However, immediate shutdown usually indicates a hardware problem. 60C is 140F which most prefer to have as a setting in their BIOS for a temp protection setting. If you want it to run hotter, check there for that setting.

Shuts down

If your over clocking anything bring it back to stock speed and test.

Remove the side panel and test.

Remove the gpu and plug the monitor into the mobo and test.
