A control unit of the power supply device receives a voltage provided by the POE system and a voltage provided by the DC power supply, and compares the two voltages with each other. When the voltage provided by the DC power supply equals or is greater than the voltage provided by the POE system, the control unit inputs electric power of the DC power supply to the NAS and prevents electric power of the POE system from being input to the NAS. When the voltage provided by the DC power supply is less than the voltage provided by the POE system, the control unit allows electric power of the POE system to be input to the NAS.
