A method and apparatus are disclosed for supplying power in electronic equipment. Thus the apparatus comprises at least one electronic component and a power supply unit that provides power to the electronic component. The power supply unit incorporates a detector that is responsive to the power output level from the power supply unit increasing beyond a predetermined limit. If this limit is breached, the power supply unit outputs a delay signal to the electronic component. This delay signal then causes the electronic component to reduce its power consumption (such as by performing dummy operations), thereby avoiding an overload on the power supply unit.
