The invention relates to a power supply module and a power supply system. The power supply module is used in a computing system as a first power supply module. The computing system further includes a second power supply module. The first power supply module and the second power supply module are cascaded in sequence. The first power supply module is in a power-supplying state, and the second power supply module is in an off state. The first power supply module includes: a load detection unit (200), used for obtaining the load of the computing system and generating a load detection value; a determination unit (208), connected with the load detection unit and used for generating determination information according to the load detection value so as to determine whether or not to turn on the second power supply module; and a power on and off unit (201), used for sending a power-on signal (PSON) to the second power supply module when the determination information indicates that the second power supply module needs to be turned on. The second power supply module is powered on in response to the power-on signal. The first power supply module by itself can automatically determine whether another power supply module needs to be turned on, thus the determination need not be made manually. The power distribution panel is simplified or even rendered unnecessary because each power supply module can be connected by wires, thus cost is saved. |
