Hello,
I've replaced my card from RTX 3080 to XFX 7900XTX, and after doing so, the PC started shutting off instantly with a tick sound on the PSU then the PC boots up back again. this is usually happening on Call of Duty MW2 in large maps like DMZ and Warzone.
Note: this only started to happen after replacing to 7900XTX, before with the 3080 (OC'd through ASUS GPU Tweak Software), this issue wasn't occurring at all.
As far as my understanding, the Recommended PSU is 850W. Thus, it managed to trip the PSU's OCP and the only way that I'm able to use the PC for gaming is to downclock/undervolt the card to 2500MHZ and 1100mV. basically reducing the performance of the card substantially from 3000MHZ.
While I ordered new parts to upgrade the PC to 14700K and salvage the existing parts as I have to do a build for my little nephews. I didn't count on a new PSU and I'm not actually ready to pay for an overly expensive Thor II 1200w PSU (My whole setup is ASUS ROG parts including the case)
