Abstract: A power supply system for an electronic device includes a power supply unit adapted to convert AC power to a first DC power, a DC/DC converter connected to the power supply unit, a super I/O chipset connected to the DC/DC converter, and a south bridge chipset connected to the DC/DC converter via a switch. The DC/DC converter is adapted to convert the first DC power into a second DC power. The switch is connected to the super I/O chipset and controlled by the super I/O chipset. The super I/O chipset is adapted to turn on the switch to have the DC/DC converter supply the second DC power to the south bridge chipset when the electronic device is turned on. The super I/O chipset is also adapted to turn off the switch when the electronic device is shut down.

Abstract: An expansion card apparatus for expanding a motherboard which complies with a first signal transmission standard with an expansion card which complies with a second signal transmission standard, includes a first slot which complies with the first standard, a second slot which complies with the second standard, an expansion slot, and a transforming card. The first slot, the second slot, and the expansion slot are defined on the motherboard. The expansion slot is configured for receiving the expansion card and electrically connects to the second slot. The transforming card includes a first connector connecting with the first slot, a second connector connecting with the second slot, and a transforming chipset for transforming form of signals between the first standard and the second standard to allow the signals to be transmitted between the expansion card and the motherboard.
