It's 280 watt, but because of the case size the power supply and graphics card are smaller or something. I found a 7600 GS Low Profile but I need a bigger power supply. Any suggestions are welcome.
See if one of PC Power %26 Cooling's Dell power supplies will work in there (or if it's even a proprietary model).
