Power circuit for reducing standby power consumption

A power supply for reducing standby power consumption, comprising:

• a primary power system;
• a stationary power system, the stationary power system outputting a stationary power for the power supply in a standby mode;
• a control unit obtaining the stationary power and being triggered by a power supply (PS) ON/OFF signal to drive the primary power system to output a primary output power,
• a switch unit including two ends, a first end being connected to the stationary power system for outputting the stationary power and a second end connected to a virtual load, the virtual load including two ends, with a first end connected to the switch unit and a second end connected to a ground point;
• wherein the PS ON/OFF signal is provided for controlling the ON/OFF of the switch unit, such that the switch unit is turned off in the standby mode when not triggered by the PS ON/OFF signal, and the switch unit is turned on when triggered by the PS ON/OFF signal and then the stationary power system is electrically connected to the virtual load.
