Abstract

A power supply device with a system switch circuit includes a primary power system, a stationary power system and a power management unit. The power management unit is triggered by a remote ON/OFF signal to generate a bias voltage power for turning on the primary power system after obtaining a stationary power. The system switch circuit is triggered by the remote ON/OFF signal to interrupt the stationary power system from obtaining an electric power path of an input power or a reference frequency signal to interrupt the stationary power, and triggered by the remote ON/OFF signal again to conduct the stationary power system to obtain the electric power path of the input power or the reference frequency signal to generate the stationary power, so as to achieve the effects of reducing a power loss as well as maintaining a normal operation of the power supply device.
