Computer shuts off after gaming

(Not sure if this is the right place; move if needed)

After an hour or so of gaming, all of my screens turn off, the LEDs in my fans shut down, and my HHD activity lights stop. However, my SATA powered LEDs still work. No error message, just a restart needed. Usually after sitting awhile it works fine again. Any idea on what it could be?

What are the parts in your system? Also what is the make/model of your PSU? Lastly what are your temps?

PSU is not that great. Depending on what the temp issue is I’m leaning to a bad PSU. Get a Seasonic or Antec PSU over a Corsair. I would upgrade the PSU before getting the new GPU.

I really cant afford a new PSU at the momento, I need a new GPU for some projects that use it, and it works just fine for every other task than CS;GO. Is there anything I can do to help the performance of the PSU? Its worked very nice.

Btw, maxed 42 degrees in one match of cs
