Abstract
A multiple power supply device including a power consuming unit, a plurality of power supply units, and a plurality of switching units is provided. The power consuming unit receives a plurality of power good signals, and outputs a plurality of power control signals accordingly. The power supply units output a plurality of working voltages respectively, and meanwhile output the power good signals. When the power consuming unit is in a working state and one of the power good signals is enabled, the power consuming unit enables the corresponding power control signal. When the power consuming unit is in a working state and a part of the power good signals are enabled, the power consuming unit enables one of the power control signals corresponding to the enabled power good signals. The switching units transmit the corresponding working voltage to the power consuming unit according to the enabled power control signal.
