I guess you are using Windows 11? I had this problem just recently, my GPU was draining 350 watts while playing, Also overheating, games crashing and pc restarting sometimes. I switched back to Windows 10 and all issues were gone, I am now getting 30% more FPS and my GPU is using 270 watts, all up and running smoothly with no issues. If you are currently on Windows 11 i suggest you switch to Windows 10!
