In this paper we use the load current of the CPU to decide whether the working state of the PC is considered to be a heavy load or a light load. Based on the voltage limit of each device on the PC motherboard, we use the voltage control as a dynamic voltage scaling (VREF-DVS) regulator to provide different voltages for each device. When the PC has a light load we can decrease the operating voltage of each device to the lowest limit to reduce the power consumption, and with a heavy load we can
