A power supplying apparatus having a power saving function and a method of supplying power with a power saving function. An auxiliary power generator generates auxiliary power in response to a cutoff signal. A main power generator senses the generation of the auxiliary power and generates main power in response to the sensed result and a first state of a control signal supplied by a set which performs an intrinsic function. Absent the power cutoff signal, the set performs the intrinsic function in response to the main power and stands by to perform the intrinsic function in response to the auxiliary power. A second state of the control signal places the power supplying apparatus in a power saving mode during which the set may communicate with another circuit. If the cutoff signal is supplied during performance of the intrinsic function, main power is sustained until the intrinsic function is completed.
