Abstract

A power supply, a power supply power control method and a computer program product, applied to the technical field of power supply, the power supply comprises: at least two output channels, each output channel has at least two output loops; energy supply module, used for providing electric energy to at least two output channels under the limitation of maximum total power; wherein the power limit current of different output loops under the maximum total power is different; the processor is used for: determining the target output channel of open load output, obtaining the configured and effective voltage related parameters of the target output channel; determining the target output loop in the target output channel based on the voltage related parameters, so that the voltage related parameters can be met; based on the power limit current of the target output loop corresponding to each target output channel, determining the maximum limit current of the energy supply module under the maximum total power. Since the power is limited based on the actual effective output of each output channel, the power utilization rate is maximized when the power is limited.
