Host electronic equipment with internal power supply adapted for supplying power directly to peripherals
First Claim
1. A power supply for internal connection in a system having a plurality of components which require different DC voltages for operation, said power supply including a housing, said power supply also including a plurality of wires extending through said housing for permanent connection to respective ones of said components, said power supply having at the face of said housing sockets for mating with external connectors to peripheral equipment, said power supply including means for providing different DC voltages on said wires and at said sockets.

Abstract
Electrical equipment such as a personal computer includes a plurality of internal components which require different voltages including low voltages of about five volts for operation. The different voltages are supplied by an internal power supply, with a voltage regulator, which is itself connected to an appropriately transformed high voltage supply typically from an in-the-wall source. Peripherals such as a FAX/modem, CD ROM, or tape recorder are powered by cables plugged into mating sockets in the face of the computer housing. The sockets, in turn, are connected to the appropriate outputs of the internal power supply to obtain appropriate voltage power directly from the host computer in the absence of a transformed connection to a house supply. A switch is provided at each of the sockets to vary the voltage there.
