The invention provides a power supply system and a method of controlling power level control parameters to minimize standby power. According to an aspect, a power supply system includes a power stage,a power supply controller configured to control operations of the power stage, a metering circuit configured to sense measured conditions of the power stage, and a system performance controller configured to be coupled to the power supply controller and the metering circuit. The system performance controller is configured to set or adjust a control parameter for the power stage based on energy conversion efficiency of the power stage. The system performance controller includes an efficiency computation circuit configured to compute the energy conversion efficiency of the power stage based onthe measured conditions, and a control manipulation module configured to modify the control parameter until the energy conversion efficiency achieves a threshold condition. 提供了电源系统和控制功率级控制参数以最小化待机功率的方法。根据一个方面，电源系统包括：功率级；电源控制器，
