In a power supply apparatus, a first relay unit relays power inputted from an outside of the apparatus, wherein the power having only one type of power specification. A second relay unit relays power inputted from the outside of the apparatus, wherein the power having a plurality of types of power specification is selectively inputted to the second relay unit. A module, connected to the apparatus, is activated responsively to the power supplied from the first relay unit. Information is acquired from the activated module, information showing a predetermined specification of the power supplied to the first relay unit. The second relay unit supplies the module with the power outputted from the second relay unit when a specification of the power inputted to the second relay unit corresponds to the predetermined specification, thereby enabling the second relay unit to relay the power to an electric load.
