A riser card includes a main body and an inserting portion. The main body includes a lower portion and defines a power supply interface. The inserting portion is coupled to the lower portion of the main body. The inserting portion can be inserted in and coupled to different expansion slots. The power supply interface can be coupled to an external power source to supply power to the riser card.

Riser card

A power supply switch apparatus includes a first interface, a switch circuit, and a power supply circuit. The first interface includes a first control signal output terminal, a second control signal output terminal, and a third control signal output terminal. Each of the first control signal output terminal, the second control signal output terminal, and the third control signal output terminal outputs a control signal according to an electronic device inserted in the first interface. The switch circuit receives the control signals and outputs a power supply signal accordingly. The power supply circuit receives the power supply signal, and provides a first direct current (DC) voltage or a second DC voltage to the electronic device according to the power supply signal.
