[SOLVED] Computer Crashes When In Game

First, the problem! When I am in a graphically intense game, my monitors will go black and after about twenty seconds or so, my PC will shut down.

Now, unto my troubleshooting thus far! I have contacted EVGA (graphics card manufacturer), as my first assumption was the card itself, went through their testing measures and was approved for an RMA. I then moved onto the Power Supply, tested the voltage as per manufacturer's (again, EVGA) recommendations and they came back positive. Moved on further to swap PSU's and the computer ran without issue for longer, but still ended up crashing after awhile. I then ran Memtest to check the Memory and that came back fine. I have been monitoring temperatures and they are all within spec, not even nearing 80°C.

Any other ideas as to what may be the cause of my troubles?

My specs -

Asus Prime Z270-A
Intel i7-7700K
G.Skill TridentZ 16GB DDR4 3200
EVGA GTX 980 ti
EVGA SuperNOVA 650
 
Have you tried uninstalling the GPU drivers using DDU and then reinstalling them from Nvidia's website?

Also, do you have anything between the PC and the wall socket? A UPS, or a power brick, anything of the sort? It could be that the PSU is going bad due to bad power from the wall socket.

I tried both of your solutions individually, in order, and neither solved the issue.

As far as your question regarding the power connection, I have it connected to a power strip for surge protection, but I have also tried a different power strip and the outlet itself with no avail.
 


Does the issue occur in only one game or does it happen across multiple games?

I have two games, Bloons TD5 (don't judge, just a good way to pass short amounts of time lol) and Mount & Blade: Warband, that are more CPU intensive and the crash does not occur across hours of gameplay. However, any other game tested (Ring of Elysium, PUBG, Day of Infamy, Insurgency, Vermintide 2, Total War: Warhammer II) causes a crash soon after loading into any graphic intensive portion of the games. I.e. when I spawn into any of the shooters and start to run around.
 
I think all that's left now are the CPU and motherboard. You say the crash doesn't occur in a CPU intensive game, so that's probably fine. Do one thing, run a CPU stress test, like Prime95 Small FFT's test. See if the system crashes. If no, then move to a GPU stress test, like Furmark or Unigine or AIDA64. See if it crashes then.

I have previously run a CPU and Memory (independent of each other) Stress Test and no issues arose. I just ran your Furmark test for twenty minutes and no problems came to my attention. A few notable things:

-Max Temp reached 82°C
-Memory Usage only capped at 6%
-Fans turned on and adjusted speed appropriate for temps
-Core usage/power consumption adjusted appropriately for temps

I note the VRAM usage as my friends and I (IT/Electric Engineering backgrounds all of us) are starting to believe that could be the issue.

Update: I have completely removed my GPU from my system, after confirming that one of the games that caused crashes could be run on my integrated graphics alone, and tested it via the aforementioned game. The application runs without issue. Mind you, the graphics settings had to be reduced and I took a small frame rate hit, but I did not suffer any of the system crashes that I did when utilizing my GPU.
