Abstract
An information handling system includes a plurality of power supply units (PSUs) to supply power to one or more system components. For each PSU of the plurality of PSUs, a power conversion efficiency profile for the PSU is determined using a power management control module of the information handling system. The power conversion efficiency profile represents a power conversion efficiency of the PSU for each of one or more power outputs capable of being supplied by the PSU. The power management control module determines a total amount of power to be supplied to a load of the information handling system, and engages a select number of PSUs to provide the total amount of power based on the total amount of power and the power conversion efficiency profiles of the PSUs.
