Abstract:
1. A power supply apparatus of a computer system, comprising: a power sequence module, for providing a plurality of voltage enable signals in turn according to a plurality of first power-good signals; a voltage supply unit, for providing a plurality of corresponding power voltages in turn according to the voltage enable signals, and returning a plurality of second power-good signals when the power voltages are output stably, wherein a plurality of components in the computer system provides a plurality of third power-good signals after the components receive the corresponding power voltages and are started successfully, and each component corresponds to each third power-good signal; and a state recording module, coupled to the power sequence module and the voltage supply unit, for temporarily storing the voltage enable signals, the second power-good signals, and the third power-good signals, and providing the first power-good signals according to the second power-good signals and the third power-good signals, wherein when a specific third power-good signal is converted from enabled to disabled, the state recording module judges a tolerance period according to the component corresponding to the specific third power-good signal, and converts one of the first power-good signals corresponding to the specific third power-good signal from enabled to disabled after the tolerance period is delayed, and the specific third power-good signal is one of the third power-good signals.
