Patent ID: 8339791

Claim:
A power supply unit comprising: a box comprising a sidewall, a rectifier enclosed by the sidewall, and a first connector being set on the sidewall and electrically connected to the rectifier; a circuit board, mounted on the sidewall, comprising a plurality of output terminals set on a first side of the circuit board opposite to the sidewall of the box, and a second connector being set on a second side of the circuit board facing the sidewall of the box and electrically connected to the first connector of the box, each of the plurality of output terminals connected to a corresponding pin of the second connector; and a power connector selectively connected to some of the plurality of output terminals via a cable and also connected to a power interface of a motherboard, wherein the power connector is connected to a first end of the cable, and a second end of the cable is selectively connected to corresponding output terminals of the circuit board according to a required input voltage of different motherboards, the power connector outputs power signals from the box to the motherboard and receives control signals from the motherboard to the box; wherein a plurality of inductive protrusions is set on the cable opposite to the power connector, and surrounds the cable, each output terminal comprises a base extending from the circuit board and a plurality of resilient inductive pieces, first ends of the resilient inductive pieces are fixed on the base and arranged in a circle on the base opposite to the circuit board, the resilient inductive pieces and the base bound an accommodating space, diameters of a first end of the accommodating space adjacent to the base and a second end of the accommodating space away from the base are less than a diameter of a center of the accommodating space, to receive the plurality of inductive protrusions of the cable, to electrically connect the cable to the output terminal.
