The present invention discloses an energy-saving device with multiple voltage levels which is applied to a motherboard. The energy-saving device includes an energy-saving driving module electrically connected to a CPU on the motherboard for generating an energy-saving signal with multiple voltage levels to the CPU, so as to switch the CPU to a corresponding operational frequency according to a voltage level of the energy-saving signal after the CPU receives the energy-saving signal. The energy-saving device with multiple voltage levels implements 256 voltage levels instead of the conventional two voltage levels, so as to achieve multiple power consumption of the motherboard. |
