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.

Multiple power supply device

The invention provides a power switch device for electronic systems equipped having a power module. The power switch device includes a first switch for activating a first signal, a second switch for activating a second signal, a logic judging module for receiving the first and second signals for logic algorithm processing, and a control module electrically connected to the electronic system and the logic judging module. The control module is adapted to generate and transmit on and off signals of the electronic system to the logic judging module. Further, the control module controls switching on the power module according to the off signal and the logic algorithm processing based on the first signal, and also controls switching off the power module according to the on signal and the logic algorithm processing based on the first and second signals.

Power switch device

A computer capable of automatic bandwidth configuration according to I/O expansion card (e.g., PCI-Express expansion card) type is provided. A motherboard of the computer includes an I/O expansion slot, a chipset, and a configuration setting circuit. When the I/O expansion slot supports different types of I/O expansion cards having multiple interface card slot combinations, a corresponding bandwidth configuration message is generated on the I/O expansion card. The bandwidth configuration message is used to indicate the type of the I/O expansion card that is being used and thereby control the configuration setting circuit to adjust the bandwidth configuration in the chipset.
