POWER SUPPLY MODULE AND POWER SUPPLY SYSTEM
First Claim
1. A power supply module used as a first power supply module in a computing system which further comprises a second power supply module, the first power supply module and the second power supply module being cascaded in sequence, the first power supply module being in a power supplying state and the second power supply module being in an off state, the first power supply module comprising:
- a load detection unit configured to detect load of the computing system to generate a load detection value;
a determination unit connected to the load detection unit and configured to generate determination information based on the load detection value for determining whether to turn on the second power supply module or not; and
a turn-on/off unit configured to send a power supply on (PSON) signal to the second power supply module when the determination information indicates that the second power supply module is to be turned on,wherein the second power supply module is turned on in response to the PSON signal.

Abstract
The present disclosure provides a power supply module and a power supply system. The power supply module is used as a first power supply module in a computing system which 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 itself is capable of automatically determining whether to turn on another power supply module or not, without any human intervention. In this way, the power distribution board can be simplified, or even eliminated, in which case the individual power supply modules can be connected by wire to reduce the cost.

7. A power supply module used as a second power supply module in a computing system which further comprises a first power supply module, the first power supply module and the second power supply module being cascaded in sequence, each of the first power supply module and the second power supply module being in a power supplying state, the second power supply module comprising:
-
a load detection unit configured to detect load of the computing system to generate a load detection value; a determination unit configured to generate determination information based on the load detection value for determining whether to turn off the second power supply module or not; and a turn-on/off unit configured to send request information to the first power supply module when the determination information indicates that the second power supply module is to be turned off, instructing the first power supply module to send a power supply off signal to the second power supply module, wherein the second power supply module is turned off in response to the power supply off signal. - View Dependent Claims (8)

9. A power supply system comprising at least two power supply modules and a power distribution board, wherein
the at least two power supply modules comprise a first power supply module and a second power supply module, both used in a computing system, the first power supply module and the second power supply module being cascaded in sequence; -
wherein; the first power supply module is in a power supplying state and the second power supply module is in an off state, and the first power supply module comprises; a load detection unit configured to detect load of the computing system to generate a load detection value; a determination unit connected to the load detection unit and configured to generate determination information based on the load detection value for determining whether to turn on the second power supply module or not; and a turn-on/off unit configured to send a power supply on (PSON) signal to the second power supply module when the determination information indicates that the second power supply module is to be turned on, and wherein the second power supply module is turned on in response to the PSON signal; or; each of the first power supply module and the second power supply module is in a power supplying state, and the second power supply module comprises; a load detection unit configured to detect load of the computing system to generate a load detection value; a determination unit configured to generate determination information based on the load detection value for determining whether to turn off the second power supply module or not; and a turn-on/off unit configured to send request information to the first power supply module when the determination information indicates that the second power supply module is to be turned off, instructing the first power supply module to send a power supply off signal to the second power supply module, and wherein the second power supply module is turned off in response to the power supply off signal. - View Dependent Claims (10)
