A power output error free apparatus includes a power supply having a circuit board inside and a power transmission port on the surface. The circuit board has a plurality of electric connection zones electrically connected to the power transmission port. The power transmission port is connected to a connection line which has a connection port on one end corresponding and connecting to the power transmission port and a coupling end on other end connecting to a computer main board. The coupling port has a ps-on (power-supply-on) signal pin to control activation of the power supply. The power transmission port has a dummy pin or HIGH potential on a location corresponding to the ps-on signal pin. As a mistaken connection occurs by switching the connection port with the coupling port, the ps-on signal cannot be transmitted through the dummy pin or HIGH potential of the power transmission port.
