Hello I've been having some issues with my pc ever since I put it together. I can play low demand games such as League of Legends, and Team Fortress 2. However when I switch to something else such as Rainbow Six Siege or Sniper Elite 3 my entire system will turn off, and the only way to get it back on is to unplug the cord to my surge protector and only then will it turn back on. I checked all of my temps. GPU is sitting at 60C when under load. Motherboard and cpu are both well within its limits.

WHAT COULD IT BE?? ANY HELP IS WELCOME!!

CPU- i5 4460
WaterCooler: Corsair H55

MotherBoard: MSI Z97S SLI Krait Edition ATX LGA1150

RAM: Corsair Vengeance 8GB

GPU: MSI GTX 970 100 Million Edition

STORAGE: Kingston SSDNow V300 Series 120GB 2.5" and Seagate Barracuda 1TB 3.5" 7200RPM

POWER SUPPLY: Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply
 
Solution
Does it shutdown if you run Furmark Burn-in Test? It could be the PSU, the motherboard or the GPU, but based on your description I suggest you test with another PSU.

Check the surge protector and outlet to make sure you have a proper ground connection. A floating ground can cause instability that seems random at times.

Double check that the PSU has airflow to cool itself, if the overtemp protection's faulty or not present, the increased power demand could cause the PSU to overheat and start messing up the output. I'd advise against opening the PSU to clean it, if you don't know what to avoid, you can give yourself a really bad shock.
