Claim Text:
1. A power supply apparatus comprising a plurality of power supply units that supply power, wherein each of the power supply units includes: a voltage conversion circuit that converts input voltage into output voltage within a predetermined voltage range; an output capacitor that outputs supply power while accumulating charges according to the voltage converted by the voltage conversion circuit; and an overload detection circuit that detects an overload of the output capacitor and when the overload is detected, notifies a processing apparatus operated using the power supplied from each of the plurality of power supply units of an overload signal requesting a suppression of power consumption of a load, wherein the overload detection circuit notifies the processing apparatus of the overload signal while output current inputted from the processing apparatus to the overload detection circuit exceeds a predetermined threshold value, the output current being return current from the processing apparatus to at least one of the plurality of power supply units.
