    Well nobody can say for certain what will happen but we can guess. It could work fine, or could not work at all, or it could work poorly, or crash or freeze, or damage the video card or cause the power supply to fail(and potentially damage other hardware in the computer when it fails). The requirements are there for a reason, the 7900 needs a lot of power, my advice is to buy a quality power supply that meets the requirements for the card.

    It also depends on which 7900 model you have. At minimum you need a 350W with 20 Amps on the 12 volt rail, or as high as 450W with 22 Amps on the 12 volt rail.

    You were told wrong, you are exceeding what the power supply is meant to deliver, something won't get enough power and that is never a good thing in electronics. The numbers aren't chosen out of the blue, they're based on research.

    T-6 is right. Don't gamble a good video card for a cheap PSU. Not worth it.

    P.S. If that PSU blows you may need a whole new system, or at least some major parts. Get a better PSU.
