A power supply system for CPU is disclosed. The CPU includes a plurality of dynamic voltage identification (VID) pins, and the power supply standard of the CPU conforms to a first standard. The power supply system includes a VID signal line set and a core voltage controller. The VID signal line set is coupled to the VID pins of the CPU, wherein the VID signal line set includes a least significant bit (LSB) signal line set and a most significant bit (MSB) signal line set. The core voltage controller conforms to a second standard and is coupled to the MSB signal line set to determine the core voltage to be output to the CPU according to the bit state of each MSB signal line in the MSB signal line set, so that the power supply system can conform to the first standard. |
