Claim:
1. A power distribution unit (PDU) comprising: at least two power distribution circuits for distributing electrical power to a plurality of devices deployed in a computing rack, each power distribution circuit comprising a plurality of power receptacles for coupling to the plurality of devices disposed in the computing rack; and an interchangeable adapter coupled to the power distribution circuits to provide the electrical power to the power distribution circuits, the interchangeable adapter electrically connectable to one of a plurality of different electrical power sources in which each electrical power source has a phase type configuration including at least one of a three phase delta connection, the interchangeable adapter comprising a first connector that is removably connectable to a second connector of a first of the power distribution circuits, the interchangeable adapter providing the power to the first power distribution circuit through the first connector, wherein each power distribution circuit comprises a housing with the second connector configured on a first side of the housing and a third connector configured on a second side of the housing in which the second side is opposite the first side of the housing so that the at least two power distribution circuits may be stacked upon each other, and wherein when the first connector of the interchangeable adapter is connected to the second connector of a first power distribution circuit and the second connector of a second power distribution circuit is connected to the third connector of the first power distribution circuit, power from the interchangeable adapter may be provided to the second power distribution circuit through the first power distribution circuit.
