A system, method and kit for forming a powered communications interface in a computer system (10) having a computer housing (12). A processor (14), a power supply (16) and a communications interface (20) are installed in the computer housing (12). The power supply (16) includes a ground rail, a first power rail having a first nominal voltage and a second power rail having a second nominal voltage. The processor (14) is connected to the power supply (16) and the communications interface (20). A booster (26) is connected to the first power rail and is used to boost power from the first power rail to a third nominal voltage and to place the third nominal voltage on a third power rail. An externally accessible connector (18) having a ground conductor and first, second and third power conductors is connected to the booster (26) and the power supplies (16) such that , wherein the first conductor is connected to the first power rail, the second conductor is connected to the second power rail and the third conductor is connected to the third power rail. |
