<p>A power supply apparatus switches between normal operation mode and power saving mode, to supply power to the loads. Power supply apparatus includes first power supply, second power supply, current detection portion, determination portion, and supply control portion. First power supply is configured to supply power to plurality of loads. Second power supply has an output current capacity which is less than that of first power supply. Current detection portion is configured to detect current consumption of first load that is operating. Determination portion is configured to determine whether or not the current consumption detected by current detection portion is less than or equal to the output current capacity of second power supply. Supply control portion is configured to supply, based on a result of determination made by determination portion, power to the first load from one of first power supply and second power supply in the power saving mode.</p> |
