Use a PCI-E power connector to supply 12 volt power to an AGP video card when the required adaptor is not available on the power supply. The power connectors on a typical ATX power supply can be adapted to supply power to any device that uses the same voltage by using a commercial adaptor. Many AGP video cards use a standard Molex four-pin, 12 volt power connector to obtain their power and a splitter or adaptor can be found in either configuration to make the connection.
