Hey guys, thanks for the replies!
I've been using the PSU since early 2021 with a 3090 before I got the 4090 mid last year. I'm aware that it is below the recommended wattage for a 4090, but it's been used successfully by many others in the small form factor community and I've never had any...
I recently upgraded to a 7800x3d system from a 5900x3d system, carrying over only my PSU and GPU, and have been having performance issues in games. Prior to this upgrade I had no issues, perfect performance and no stuttering or crashes.
