Then there's the ATX form factor constraint. So any PSU has roughly the same amount of components... The most expensive one being the MOSFETs, doubling em would send the price through heavens. All they do is put bigger MOSFETs (and higher power rated components). So don't take for granted that this 550W PSU will run cold with your system if it was previously powered by a 300W... You're better off with a more efficient 300W to begin with.
