Computer restarting during CS:GO and Fortnite

[chancemitchell]

PSU: ATX-CB800W
GPU: NVIDIA Geforce GTX 970
Motherboard: X58A-GD45
SSD: Samsung EVO 850 500GB
HD: Hitachi something
Memory: 2X8GB G-skill Ripjaw

Fortnite restarts my PC everytime I press Battle Royale Button, cs:go restarts my PC randomly throughout game. Sometimes I can play CS but not Fortnite sometimes if I start with CS and go to Fortnite it lets me in, but after it restarts once it will just continue to restart every time at the Battle Royale button. I just installed new 2X8GB RAM flashed my BIOS and re-installed Windows fresh. Graphics Card is less then a year old and case is sitting around 82-91 degrees F. I thought it was a RAM issue because my PC wasn't recognizing my old RAM but that turned out to be solved after BIOS flash. It has occurred both before and after new RAM, BIOS Flash, and fresh windows install. The computer completely restarts no error messages or blue screens, and starts up no problems. I don't know what it could be, anybody have any ideas on how to troubleshoot this problem/fix this problem. Sometimes it let's me through to the Lobby on Fortnite after it has been sitting shut off but once it starts restarting I can't get passed Battle Royale button.

A Google search suggests you have an Apevia PSU-shaped object. Likely good for half its label at most, it is probably overheating, wandering out of spec, and/or shutting off. Please replace it with a real PSU before it kills your system. On a tight budget, a Corsair CX-550 would do; better would be a 550W Seasonic Focus or Focus+.

Hey! Thanks for the response, it seems a consensus this PSU is trash. What would your recommendation be for a 800-850W PSU. I have a GTX 1080 coming in the mail.

A good 650W PSU would be sufficient. I personally prefer Seasonic PSUs; the last one I bought was a Focus+.

Ok I ordered a Seasonic 850W Focus+ Gold. I just want a little extra wattage in case of future mods. I just stuck with the focus+ upon your recommendation.
I will come back and mark your comment the solution if resolved.

While that is a lot more than you need, it is otherwise a high-quality choice. I think you'll be happy with it.

Replacing my PSU seemed to have fixed the issue thanks Onus for your input!
