I have a DELL E521 pc im wanting to upgrade the video card on it. Dell put a very low power supply (305W), and gave very little room for a bigger video card. Also any other advice on upgrades for the ram/psupply would be great.
Pc power and cooling "silencer" units are recommended for a dell upgrade. Newegg has a 500w unit with 35 amps on the 12v single rail for $49.99 after rebate. But you'll have to do some measuring for any high end card to see if it will fit the dell motherboard.
