1. An information handling system comprising:
- plural processing components operable to cooperate to process information;
a power supply operable to provide power to the plural processing components;
a protection circuit associated with the power supply and operable to shutdown the power supply upon detection of either a predetermined thermal constraint or a predetermined output constraint at the power supply; and
a protection constraint adaptive module interfaced with the protection circuit and operable to dynamically adjust the predetermined thermal constraint and predetermined output constraint based upon thermal and output measurements associated with the protection circuit.

Abstract
An information handling system power supply dynamically adapts thermal and power output protection constraints based upon thermal and power output conditions measured at the power supply. In the event of changing conditions at the information handling system, such as an increase in ambient temperature or an increase in power consumption, a power constraint adaptive module adjusts constraints at which the power supply will shut down in order to maintain power to an information handling system outside of a normal power and thermal constraint operating envelope for the power supply.

10. A method for powering an information handling system with a power supply, the method comprising:
-
monitoring power output by the power supply; shutting down the power supply if power output exceeds a power output constraint; monitoring a temperature associated with the power supply; shutting down the power supply if the temperature exceeds a thermal constraint; and applying the monitored power output and monitored temperature to dynamically reset the output constraint and the thermal constraint. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
