An information handling system may include a power system comprising a plurality of power supply units and a management controller communicatively coupled to the plurality of power supply units. The management controller may be configured to monitor real-time direct current (DC) power consumption by components of the information handling system, determine an effective output capacity of each of the plurality of power supply units, and based on the real-time DC power consumption and effective output capacity of each of the plurality of power supply units, determine a real-time power supply unit workload attribute that indicates a number of the plurality of power supply units required to provide the real-time DC power consumption.
