My desktop dies randomly but only when playing a few very specific games.

I can't really figure this one out. I built it myself over the years and put a new graphics card in less than a year ago. My computer runs perfectly fine until I start playing a few, very specific games. I can play 90% of my library (I've tried XCOM 2, Don't Starve, Sunless Sea, The Witcher, etc) no problem, but if I try to play Starcraft 2, Depth, or City Skylines the computer just dies. It isn't immediately. It usually happens after 30 minutes of Starcraft, several hours of city skylines, and less than 5 minutes of Depth. No other games have this problem (that I am aware of at least). It has no warning or error message. The screen just goes black and then boots back up.

I initially thought it must be overheating. The GTX 980 runs a bit hot at idle (45-50 degrees C) but I've tested it and kept an eye on the card and at the time of shutdown it has never been above 70 before dying. The CPU and the Motherboard aren't going above 45. I've never overclocked anything either. (temps collected by the free version of Speccy) None of the heat syncs feel especially to the touch hot either.

I then tried updating the drivers, but that didn't work

Then I thought it might be a defective GPU. So I put my old GTX 560 but the problem still persists.

I'm at a loss. What do you guys think? What should I try next? Thanks for any help you can give! I really appreciate it!

Specs:

MoBo: Gigabyte Z97X-UD5H
GPU: Geforce GTX 570 (also tested with my old GTX 560)
CPU: Intel i5 4690-k @ 3.5GHz
PSU: Corsair HX-750
HD: Samsung SSD 850 Pro1TB
RAM: 8 GB DDR3


 
Solution
Check you PSU, remove it in your cpu case and use a paper clip to power up, use a voltmeter to check the voltage output is normal like 12 volts, you can use also a new psu with the same specs or higher then try to power-up. Be sure to remove dust buildup in your computer.
