Systems and methods are disclosed for allocating and distributing power management budgets for subsystems (e.g., power usage clients) of a computer system. A power budget allocation subsystem may include a plurality of feedback branches having different associated time constants. Power usage clients with slower power response times may be provided power budgets based on a feedback branch having an associated longer time constant, while power usage clients with faster power response times may be provided with power budgets based on a feedback branch having an associated shorter time constant. The power budgets may be determined in the feedback branches based on power budgeting policies weighting the power budget of each subsystem relative to total power mitigation.
