Efficiency and Off-Power
The following table shows you the efficiency we measured with the different power supplies at a load of 50 percent which corresponds to highest possible efficiency due to the fact that modern power supplies have their efficiency-peak at 50 percent of their maximum load.
With our Off-Power values we show the amount of power which is being drawn from your power plug when your computer is switched off. It is interesting to see that these values differ quite gravely.
