550W is plenty for that system. I wouldn't worry about it. The system will probably need only 300W or so running at 100%. Even the "requirements" for the card are like 400-450W and probably 30A(?) for the +12 rail. Those assume a whole system, not just the video card. The PSU is rated at 42A... nowhere close to the limit.

i really would not run that power supply, id use atleast a 650W. but then again, i like my systems to work without me worrying whether it is going to crash or not. it might just run on 550, i wouldnt doubt it, but a psu that says 550 doesnt mean it is 550, it could be rounded up from another number. 500 still may even be well enough, and you are not overclocking. the psu you have now might be fair enough. i just would upgrade if i had the chance too.

nvm

with his setup he needs only 403-420W

You're just wasting power and money. The GeForce 8800 GT has a minimum recommended PSU of 400 Watt, so the 550 Watt is still pretty much overkill.
