    Each of the mini 6pin graphics card power connectors (PEG) should be able to provide 150W each (150W = spec anyway). The 8 pin PEG spec is rated for 225W (so if this port on the card draws more than 150W, it will damage the PSU and may burn the traces on the logic board).

    From what I've seen on the card, the GTX480 is rated to pull 305W (75W is provided by the PCIe slot itself). That leaves 230W to be supplied by the PEG connectors (6 + 8). So the MP's PSU should be able to provide it (assuming it meets specification, and not sort-of ; it does happen ).

    unquote..

    so i guess that mean the MP would be up for running the 480 then?? anyone have any input?

    cheers
