Fortnite has had issues in the past with causing reboots.
Supposedly fixed by patch releases.

If it's a poor quality and/or older power supply it could just be giving up and causing your issues.

But its not happening on every game though only on some of them

My firs suspect for these random reboots would be the GPU. But testing and verifying the memory on the GPU is next to impossible. And to rule out something easy like your main system memory, you probably should do a memtest86 on that, but chances are you would not find anything there. So if possible, borrow a video card from someone else, worse yet buy a gtx1060 and return it afterwards. And as far as it being just some games, I bet if you tried hard enough and test them all thoroughly you'll find the crashes on all game. I had video card flake like the symptoms you described. Eventually only by replacing the GPU did the problems finally stop.

Doesn't matter , could still be an unstable PSU.
