Not too long ago I purchased a used zotac 3070 and whenever I played certain games with it, it would shut off (only the gpu) whenever it was under full load and reached 77-80 degrees celcius. I thought it was probably a defective card so I purchased a 3070 Asus TUF edition and to my surprise I'm facing the same issue. I did some research and realized that perhaps my PSU was the culprit since it's only a 600w psu and the minimum for a 3070 is 650. I purchased a CORSAIR RM750E last night and low and behold the issue persist. It only happens with certain games like flight simulator and Fifa 23 to be precise but I'm sure the temp isn't the reason it's shutting down since 80 degrees should be bearable for this card. I had the pc connected to a UPS and thought that maybe that was limiting the power so I connected it directly to the outlet on the wall and it's still happening. Not sure what to do. I must mention that the only way around the issue right now is to limit the framerate in flight simulator so the gpu doesn't get taxed.
