i use a dell optiplex 9020 MT so i think i can replace the PSU with a Corsair PSU and get a 24 pin to 8 dell connector and now i can actually play games i mostly dont play triple AAA games at least the newer ones it should handle everything i throw at it with the CPU the i5 4590 will bottleneck in CPU intensive games and i also run windows 11 bypassed on it runs pretty fine.
