    RX Vega 64 causing PC to shut off while playing PUBG

    theacclaimed

      I am experiencing the issue when playing PUBG. While playing the match, randomly during the match the entire computer will shut off. Afterwards, pressing the power button will not turn the computer back on. I have to flip the switch on the back of the PSU before pressing the power button to get the computer to restart.

       

      I currently have the following test system:

       

      GPU: RX Vega 64 (tested both reference and a Sapphire Nitro+ RX Vega for comparison)

      CPU: Ryzen 1800X

      Mobo: MSI X370 XPOWER Gaming Titanium (latest bios)

      RAM: 16gb 2933mhz

      Display: Triple AOC Agon AG241QX 1440p 144Hz freesync

      PSU: Seasonic Prime Titanium 1000W

       

      I'm thinking of getting a 1200 or even 1500 watt PSU for RX Vega 64 since this never was happening when using the old R9 Fury. Playing PUBG at 1440p 144Hz freesync I see power consumption over 600 watts from the wall measuring with a Kill-A-Watt from Fry's. Maybe the Seasonic cannot handle the load spikes but I doubt they go over 800 watts so a 1000w should be sufficient. I tested with the computer plugged directly into the outlet wall as well as with a surge protector strip and see the same result.
