WRONG! The supply itself consumes a certain amount of power (even if the load is drawing NOTHING). Where it is hard to get high efficiency, where you waste a lot of power, is when the actual demand is LOW compared to the total rated output. You want some "reserve", but you do NOT want a supply rated at twice what you actually need.

Most PSUs run most efficiently when they're not running above 50% if their rated capacity. Therefore, to save electricity, get a good quality PSU rated at twice what you think you need.
