What is considered the efficiency of a computer power supply?

powersupply1Efficiency is the amount of power that a power supply can generate compared to the amount of power that it needs from an outside source to do so. For instance, a power supply may need 100 W of input to put out 80 W of power, making it 80% efficient. The rest of the energy is wasted as heat, which is important to cooling considerations. For instance, the above power supply would put out 20 watts of power worth of heat into the case into which it was installed, which may necessitate more cooling or which may be handled adequately by the power supply’s native cooling system.
