    Is this power supply good for a gtx280 superclocked?
    If it doesn't supply enough amps through the 6 & 8 pin connectors I may end up under powering your GPU under heavy loads. (Minimum recommended power supply with +12 Volt current rating of 40 Amps.)

    These cards need two seperate PCIe power wires. One 6 pin and the other an 8 pin (or 6+2 pin). This card comes w/ an adaptor for the 8 pin to make it 6 pin though!

    Would an Ultra LSP 650 be good enough? Like does it have the wires I need?

    Im just looking for a cheap solution with these specs. If anyone can help that would be awsome!

    ( reason for buying another psu is so I dont have to order any wires for this card to work under windows in the mac pro and I can ensure ill have enough power for a fan too )

    Why don't you just tap the two 6-pin ports on the Mac Pro's logic board?

    No need to buy a separate power supply, jerry-rig the setup and risk barbecuing your system.

    That power supply you linked is a POS.

    Get a Corsair VX550 or TX650 instead. Trust me.;)

    ya then I would have to order like 3 wires from 2 diff sites and then take that chance when I can just buy this down the street and it comes with the cables, or does it not?
