Abstract
A computer system comprising a motherboard and a power supply having an associated power management bus controller with memory storing the power capacity of the associated power supply. A power circuit provides power from the power supply to the motherboard, wherein the motherboard has a processor and a baseboard management controller. The system further comprises a power management bus providing communication between the baseboard management controller and the power management bus controller associated with the selected power supply, wherein the power management bus controller provides the stored power capacity to the baseboard management controller. This allows the baseboard management controller to limit operation of the processor to control the amount of power consumed from exceeding the power capacity of the selected power supply. The power capacity of the power supply may be sent to the baseboard management controller in response to booting the motherboard.
