pc shuts down when rx 5700 xt pcie 3.0

Sometimes when im loading in to the game (apex, space enginers etc.) computer just shut downs and cannot be turned on.. i need to turn off cumputer via psu.. i have 600w psu so it shouldnt be problem.. i tried to update bios a manually set from automatic pcie to pcie 3.0 but that didnt helped.. so i tried another pcie slot that is 2.0 2x4 and my graphic card worked fine even under heavy load..

driver version: 19.9.2

cpu: ryzen 1500x

motherboard: gigabyte ab350-gaming
connected 2 1080p monitors
1ssd + hdd
16gig ram
windows home edition latest version

what i have tried:
reinstalling windows
updating bios
changing psu and connecting gpu to 2x 12v lines
reinstalling drivers with ddu
i tried to watch temperatures and maximum was 80 celsius

only switching to another pcie that is 2.0. 2x4 helped

There was the same problem with the MSI b450-A Pro, it was decided by BIOS firmware to the latest version(AGESA Combo 1.0.0.3ab)

A system with 5700xt does not consume more than 400 watts on a 12 volt line. So, I think that the problem is still not in the power supply. Moreover, as you say, with pcie 2.0 everything works as it should. The problem is definitely in the motherboard.

I think you should contact a gigabyte and report your problem. Perhaps they will send you a revised version of BIOS.
