PC randomly shudding down

[Willi_st]

First, my System: R7 5800X, Noctua NH-D15S, Gigabyte Auros B550 Elite AX V2, 16GB of DDR4 Ram, XFX RX 6800XT MERC 319, Corsair RMx White Series RM850x, 1x 512GB Gen4 SSD from Aorus, 1x Sata 2TB SSD, 1x 2TB WD HDD, 4 Case fans, Phanteks Eclipse P600S Silent, Xiaomi Mi Curved Gaming Monitor
So when playing Far Cry 6, Cyberpunk or Sea of Thieves my PC randomly shuts down, Screen black in an instant and only the RGB of my Motherboad is still on, everything else is off. The only way to boot the PC again is to turn the PSU off and on again than the PC works fine again. This typically happens after around 30mins up to 2 hours of playing these games. I don't have this problem in any other game. I haven't overclocked anything besides enabeling XMP and have also tried turning XMP off. All my drivers are up to date as well as the BIOS. 

Earlier I had this and the PC just wouldn't turn on, I than switched my GPU for a 580 form a friend and than updated my Bios and it worked again and now I have to turn the PSU off and on to get the PC working again.

Im not the smartest in this type of problems but i recommend trying to clean out the dust you might have in your PC couse it might be over heating

Just did, ramped up my case fan speed and it is still happening

What is the temperature of the CPU after some time playing one of the above games? It definitely looks like either an overheating issue, or  maybe a bad PSU. Is you don't have another PSU to try, verify that your cooler is actually keeping the CPU cool enough.

Not sure if the games have it, but have you tried playing on stable graphic APIs such as DX11 and not Vulkan as sometimes it can cause issues in the long run that causes something similar to this, I've had it from experience.

Looks to me like this is a power issue, or maybe a driver issue really.

Have you tried to DDU or maybe have you increased or decreased the maximum allowed power draw by your GPU?

I found that increasing the power allowance on the GPU does wonders sometimes to intensive games.

Shutdowns of your system are due to it being inconsistent. The ram must have twice the amount of memory than the video card.

My CPU ist sitting at around 75 to 80 Degrees Celcius

These Games only support DX12 as far a I know... 
I have tried DDU and reinstalling my Drivers.
How do I decrease the allowed power for my GPU? XFX doesn't have a Fan/Power tuning program as far as I know.

You should be able to do it using AMD's Radeon Software I believe?

Just tried undervolting and decreasing the GPU load,my GPU was sitting at 60% usage and 70°C, just happend again after 3 hours
