Say I have a 400W PSU running at 80% effeciency, and I leave it on for an entire month, how would I calculate how much power it used?? Is there a calculator on the internet somewhere?
*I know I wouldn't be using the full 400W constantly, since that's only really at max load, but I'd like to know theoretically how much power I would be using maximum, that way I can take a percentage of that, and see how much it would cost to leave it on constantly.
