Abstract
A power supply system includes a power supply unit, a voltage converting unit, a comparison unit, and a switching unit. The power supply unit is configured to provide working voltage for a motherboard via a first resistor. The voltage converting unit includes a voltage converting chip. The voltage converting chip is configured to detect a first direct current (DC) voltage on the first resistor, and convert the first DC voltage to a second DC voltage. The comparison unit is configured to receive the second DC voltage, compare the second DC voltage with the working voltage, and output a switch signal. The switching unit is configured to receive the switch signal, and output a control signal to a central processing unit (CPU) on the motherboard according to the switch signal. The CPU is configured to adjust its frequency according to the control signal.
