Abstract: A power management system includes a first power grid coupled to a first circuit breaker, and a first power distribution unit coupled to the first circuit breaker. A server device includes server components, and at least one first power supply unit coupled to the first power distribution unit. A power management subsystem in the server device is coupled to the server components and the at least one first power supply unit. The power management subsystem monitors a first input current draw of each first power supply unit, and determines whether the first input current draw exceeds a first input current limit that is based on the first circuit breaker. In response the first input current draw exceeding the first input current limit, the power management subsystem throttles the server components to reduce the first input current draw below the first input current limit.
