The power controller is configured to: identify an enhanced power state during which a maximum power required by the information handling system is greater than the amount of power provided by a primary psu of a redundant configuration of psus; and allocate a portion of the unused operating margin of backup reserve power from the redundant psus to support intermittent power transients that occur during enhanced power state operation.
