RX Vega 64 reboots PC, power limit related

Hi everyone!

I have an 8 months old Gigabyte RX Vega 64 Gaming OC.

Yesterday I opened Anthem for the first time and after minutes of gaming, my PC rebooted by itself. I retried and it rebooted again.

I tried to open OCCT and I run a GPU only stress test. At stock settings, the PC reboots after 5 to 10 minutes. In turbo mode, after 1-3 minutes.

With a custom power limit of +50% it reboots instantly.

Power limit at -10% or less seems to be stable.

However, games like Fortnite, COD WWII and many others work fine event with power limit at +50%.

Temperatures are ok.

I have no idea if it could be a PSU or a GPU problem.

I have also tried with a clean install of AMD drivers.

The PSU is a Cooler Master V850.


What do you think? GPU or PSU?
