Abstract:
A high efficiency heat dissipated power supply comprisinga base and a cover; the base receiving power from a plug at a rear side thereof; the voltage of the power being reduced and rectified by an electronic circuit on the base for being used by a computer mainframe; an exhausting fan installed at a rear side of the base so that the fan moves air between the cover and base; and then causes the air to flow out; at least one cover fan installed in an interior of the cover; the at least one cover fan being actuated by a power source; outer air being absorbed by the cover fan and then flowing into the cover to blow the air to the electronic circuit; then the air is exhausted by the exhausting fan at the rear side of the base; thereby, air flows so that convection air is formed at the interior and exterior of the power supply; a front fan at a front end of the base; the front fan being a suction fan; the exhausting fan, the front fan and the cover fan in the cover being formed as a fan group; wherein the plug is connected to a receptacle at a rear side of the base through an electronic switch; when the power supply supplies power to a computer mainframe and the computer mainframe is actuated, the receptacle transfers power to a connected peripheral or another receptacle through an extension line; and wherein when the mainframe is closed, the electronic switch is operated so that the receptacle is turned off and thus the power does not flow through the receptacle; thereby, no power is transferred; thus, the power supply has the function of transferring power and by turning on or off the computer mainframe, output of power can be switched automatically.
