I have a big stability problem on my Archlinux system, I’m not doing anything that requires a lot of resources and the computer for no apparent reason stops the power suddenly (it’s like plugging in and re-plugging the power plug) and it started since I changed my 5700 XT to a 6800 XT.
At first I thought that the problem was related to my “EVGA SuperNova G3 - 750W - 80PLUS Gold” I changed it against a “Corsair HX 1000W” but the problem persists.
But with Windows 10 I do not encounter this problem it is surprisingly stable, even if I pass GPU passthrough and it is stable I can make long series of hours of games but when I stop the VM the sudden stops start again .
I tested a live Manjaro and the problem is also present.
