PC shuts down when playing or loading games

The problem started when in the middle of playing pubg, it shut down/restarted during the game about 3 times but i thought it was the outlet my PC was connected to was faulty turns out its fine. Then when loading radical heights to try it out I got as far as the loading screen then my PC turned off and restarted.

Any answers? I'm thinking either CPU or my power supply. They're the only oldest parts in my build right now hitting around 4 years or so.

  1. Sounds like the power supply can't hack it. Which one are you running?
    Have you checked temperatures?

    Running a smart 750w thermaltake 80 plus bronze edition, just curious cause it should be plenty of power for everything.

    Checking temperatures while running, they were hitting about 50°C or like 100°F so looks like my PC its just way too hot
  3. 50C isnt hot for a cpu, gpu, etc. If you said 90C, Id be worried. Still think its the psu. What hardware are you running?
