Well, how much amps can a computer power supply supply? If the rating is say 250watts, does that mean 250/input voltage (250/120), or does that mean 250/output voltage (250/12)? Besides, I was under the impression that each rail in a computer power supply is designed for a different amount of current, and if I were to open one up, I'm not sure where to tap in before the power supply splits up into the individual rails. If you've done it before, I'd appreciate some explanation on what to be looking for and how to find out how much current the power supply can take.
