Abstract
A system includes power supply units (PSUs) to supply power to components. For each PSU, a power conversion efficiency profile is determined. A maximum amount of power consumed during operation of the components is determined. A minimum number of PSUs capable of providing the maximum amount of power is determined. A first amount of power consumed at inputs of the minimum number of PSUs is calculated based on the maximum amount of power and based on the determined power conversion efficiency profile of each of the PSUs. A first number of PSUs to engage is determined, the first number greater than the minimum number of PSUs, wherein a total amount of power consumed at inputs of the first number of PSUs during operation of the system is less than the first amount of power, the determining based on the power conversion efficiency profile of each PSU.
