Abstract:
1. A power output apparatus, comprising: a power supply which has a circuit board inside and a power transmission port on the surface thereof, the circuit board having a plurality of electric connection zones of varying potentials, the power transmission port having a plurality of connection members connecting to the electric connection zones to equip with the varying potentials; and a connection line which has a connection port on one end corresponding and connecting to the power transmission port and a coupling port on other end connecting to an insertion dock of a computer main board, the connection port and the coupling port having a plurality of pins in an arrangement of pin locations corresponding to the power transmission port to transmit the potentials; wherein the coupling port has a ps-on (power-supply-on) signal pin at a pin location corresponding to the insertion dock of the computer main board to transmit a ps-on signal to activate the power supply, and the power transmission port has a dummy pin or a HIGH potential at a pin location corresponding to the ps-on signal pin of the coupling port, so that if the connection port and coupling port are reverse connected, the ps-on signal from the computer main board will not be transmitted to the power transmission port; wherein the corresponding pins of the connection port and the coupling port are jumping connected through the connection line to form different potentials; and wherein the power transmission port groups pins at the same potential in adjacent pin locations.
