480 watts is really light weight for most modern PC's. With the increased memory (Ram), bigger HD's, memory intensive Graphics cards, and all the other peripherals, you might be lugging down a voltage or 2. Get a bigger PS. 750 watts should be ideal. You don't want to fry other components with brown out conditions. just look what these do to refrigerators, etc.
