I bought this: https://www.overclockers.co.uk/ocuk...zen-5-2600-rx-590-8gb-graphics-fs-1aq-og.html

I selected the Vega 56, 16gb RAM and Ryzen 5 2600.

I unplugged all USB devices (except mouse and keyboard)
I completely uninstalled GPU drivers with DDU and reinstalled the latest drivers
I moved the computer further away from the wall
I turned off the heating in my room
I checked the GPU and CPU temperatures, they are normal

RDR2 consistently switches off my PC when entering certain towns and during certain missions at 1920x1080 60fps, but only sometimes at 3840x2160 30fps. Same thing with certain Gears 5 levels. It seems to occur after 15-30 minutes of playing. Older games rarely switch it off, if ever. No bluescreens, no shutting down screen. Just OFF.

I done all those things above individually and then all at once, and it still consistently switches off at certain more graphically intensive areas in newer games at higher FPS. What could be the issue? Could you guys suggest some more tests or something? It's pretty complicated to talk about on the phone and I'd rather get your thoughts here first.
 
I'm certain it's stock speeds, I haven't overclocked anything at all. I walked into the area in RDR2 where it switched off at 2k 60fps and my CPU temperature was 72c and the GPU was 61c (MSIAfterburner). I tried Cinebench 4 times, the CPU went up to 76c and it didn't switch off. I tried Heaven bench twice, the GPU went up to 66c and it didn't switch off. But the town Rhodes in RDR2 switches off every single time at 2k 60fps (sometimes Valentine at night too) with those lower GPU and CPU temps. It never switches off at 4k 30fps.

I use Vsync in the games for locked 60, "half" refresh for locked 30. I'll try out HWinfo now. Any graphs I should look out for and maybe take a screenshot of?
 
It said an 850w PSU with the Vega 56 when I bought it. The page now says 1000w PSU... Maybe they put in a cheap one and I'll have to buy a proper one? The PSU is hidden in the case and I'll have to take it apart to check which one exactly. What's a good PSU that won't have these issues with my system? (Vega 56, ryzen 2600, 16gb RAM)

I'll do what you said and see how it goes. Will it damage my PC with it shutting off while testing? I'm surprised 4k at 30 has less issues.
