First, can anybody give me an educated guess on my Pc's power supply wattage based on its specs? Second, how does power supply wattage translate into electricity use and does a greater wattage always use more power than a smaller regardless of what the PC is doing? Are PCs Energy Star rated? That doesn't seem to be the case.

Thanks.
