Hello, I just bought a Dell Optiplex 7040 for my dad in hopes of shoving some hardware in it to make a Decent little Gaming PC he can play Civilization 6 on. The Optiplex 7040 i bought is the Normal tower Version not SFF and i see that the Computer comes with one of them Weird PSUs that are custom made for the computer itself and knowing that i was wondering if i could replace that PSU with a more conventional Seasonic or something.
