A desktop computer uses between and 2watts , depending on whether it is idle. A 22-inch LCD monitor uses an average of watts , while an older 17-inch cathode ray monitor would use about watts.
While plenty of popular, free utilities display the power usage of common components, a whole-system picture is harder to obtain, especially one that . Laserprinters trekken overigens ook behoorlijk stroom uit de doos. Dit natuurlijk alleen tijdens het printen.
