CPU Power Usage

From OCAU Wiki

Different CPUs use different amounts of power. Power is measured in Watts (W). A CPU usually generates approximately a similar amount of heat (again, in Watts) as it absorbs in terms of electrical power. This then has to be removed using some form of cooling mechanism.
