The 1080 GPU is not a light load and if the PSU is one of the usual dual or quad rails it will buckle under the load.
Be aware it could have worked when newer but PSUs and such age.
My pc often shuts itself down and automatically restarts. It only happens when a game is running, most of the time when there is a loading screen or right after, or when I change the settings of a game. I thought it could be my graphics card, but after replacing it, this still happens. (I wanted to buy a new one, no matter what, so no money lost )
So, what happens and when:
-When: When I start running a game; when there is a loading screen; when I change the settings of a game; once in a while random while gaming; NEVER when there is no game running, so not with YouTube, Internetbrowser, ...
What: PC just shuts down, as if there is a power reset (fans keep spinning), and immediately restarts again
Sometimes, this doesn't happen in weeks, but other times it just keeps happening every time I try to game. Does anyone know what the problem could be and how I can fix it?
