    Hi Everyone,

    Can someone please explain where the 7900GS (and similar cards
    needing a dedicated power supply) draws its power from? I mean,
    there's a power cord alright, and one end goes into the card itself,
    so where does the other end go? Into the motherboard? Into the SMPS?
    Or a plug point on my wall?


    And what is a PSU? Something which powers a graphics card?

    They don't need a Dedicated Power Supply just for themselves, they draw power from the PSU that powers the rest of your system.

    the psu is the device that converts the power from your wall outlet to power that your computer components can use. most of the time its mounted in the top of the case, with a lot of wires coming out of it.
    the graphics card is powered by electricity that is coming from the plug(and that cable comes from the psu) and partly by the slot its in(which also gets its power from the psu).
