    Could someone kindly tell me how much power can be drawn from the power port of logic board for the graphics card on a Quad G5?

    Any card that supports the G5 will be well under the power limit.

    Thank you for your reply. I'd like to use more than one card, such as an FX4500 plus an ATI x1900xt. Is it viable? In an PC one PCIE slot may provide about 75W, is that also true for G5?

    75w from PCIe slot and 75w from 6-pin booster cable.

    That is required (150w) for both 7800GT / X1900 / Quadro FX4500.
