Power management system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a power management subsystem that is configured to:
• monitor a first input current draw of at least one first power supply unit that is coupled to a first power grid via a first circuit breaker;
• determine whether the first input current draw exceeds a first input current limit that is based on the first circuit breaker;
• throttle, in response the first input current draw exceeding the first input current limit, at least one system component to reduce the first input current draw below the first input current limit;
• and
• adjust the first input current limit to reduce a current draw difference between the first input current limit and a throttled current draw that results when the at least one system component is throttled, wherein the reduction of the current draw difference is based on a policy to reduce stranded power on the at least one power supply unit.

A method for power management, comprising:

• monitoring, by a power management subsystem in a server device, a first input current draw of at least one first power supply unit in the server device that is coupled to a first power grid via a first circuit breaker;
• determining, by the power management subsystem, whether the first input current draw exceeds a first input current limit that is based on the first circuit breaker;
• and
• throttling, by the power management subsystem in response the first input current draw exceeding the first input current limit, at least one server component in the server device to reduce the first input current draw below the first input current limit;
• and
• adjusting, by the power management subsystem, the first input current limit to reduce a current draw difference between the first input current limit and a throttled current draw that results when the at least one server component is throttled, wherein the reduction of the current draw difference is based on a policy to reduce stranded power on the at least one power supply unit.
