The box that converts your delusions of unlimited power into 12 volts, actually.
means A device that converts electrical current from an outlet into the specific voltages a computer or gadget actually needs to run.
from A plain compound of 'power' (from Old French 'pouair,' to be able) and 'supply' (from Latin 'supplere,' to fill up, complete). No hidden story here — the name is exactly literal: a unit whose job is to supply power, nothing more poetic than that.
