A power interface card includes a processor, an external connecting port, an external power connecting port, an IDE connecting port, and an internal power cord. The internal power cord is connected to a switch device and a plurality of hardware power connectors. Thus, the video and audio access medium is directly driven by the external electric power without needing the electric power from the power supply of the computer host, without having to start the BIOS of the computer, and without needing the source from the mother board.
