1. A method of selectively providing power to a plurality of electronic devices, said method comprising:

  • supplying input power to a power supply having a power conversion circuit;

    selecting one of said plurality of electronic devices to which to provide power, each of said plurality of devices requiring at least one of an operational voltage and an operational current;

    providing output power from said power supply to a first input terminal of said selected electronic device, said selected electronic device receiving said output power characterized by at least one of said operational voltage and said operational current of said selected electronic device;

    selecting a connector from among a plurality of connectors, said selected connector having a first end adapted to couple to said first input terminal of said selected electronic device, a second end adapted to couple to an output terminal of the power supply, and a programming resistor;

    coupling said first end of said selected connector to said first input terminal of said electronic device;

    coupling said second end of said selected connector to said output terminal of said power supply so as to electrically couple said programming resistor to said power conversion circuit; and

    converting said input power to said output power based on a resistance of said programming resistor.
