Abstract
The present invention provides a system and method for controlling delivery of electrical power to a circuit board in an information handling system. A power management system is operable to detect an expansion circuit board that is operably coupled to a main system board of an information handling system. The power management subsystem detects the status of a cooling system associated with the expansion circuit board and is operable to control the amount of power delivered to the expansion circuit board based on the status of the cooling system.
