Mouse, keyboard, and monitor shut off while playing games

[andrew.andric2006]

When I was playing gta v and scp secret laboratory my keyboard, mouse, and monitor shut off randomly.
I can confirm it's not a overheating issue (when I check the cpu heat it's usually 50-60 Celsius)
Specs:
AMD Ryzen 7 2700x
2x8 gigs of RAM
Thermaltake toughpower grand rgb 850w
RTX 2080
MSI X470 Gaming plus
All air cooled
Thank you for your time, wether or not you can help.
