So i’ve been thinking on possibly upgrading my GPU and it might seem silly too. But i figured it was the culprit for my past threads ive posted with monitor screen going black randomly. I was looking at the 4000’s series GPU’s from Nvidia and i saw ATX 3.0 for the 4090. I was wondering if my PSU even has that, it is a Corsair HX1200W Fully Modular 80+ Platinum. I feel my MSI Rtx 3090 ti suprim is having issues, i can still use it and game on it but i notice it struggling a lil bit. I dont know how to describe it, it is a functioning gpu but the guy i bought it from was used. I paid around $1,200. I dont think my cpu will be any issue if i were to upgrade it is an I9-10850k. But all in all would my psu be ok if i did upgrade?
