SYSTEMS AND METHODS FOR POWER SUPPLY DERATING

摘要

An information handling system may include at least one information handling resource, a power supply unit for supplying electrical energy to at least one information handling resource, and a controller. The power supply unit may include an ambient temperature sensor for sensing an ambient temperature ambient to the power supply unit and a component temperature sensor for sensing a component temperature of a component integral to the power supply unit. The controller may be communicatively coupled to the power supply unit and configured to receive signals from the power supply unit indicative of the ambient and component temperatures, determine an ambient sensor-based power rating for the power supply based on the ambient temperature, determine a component sensor-based power rating for the power supply based on the component temperature, and select a maximum of the ambient sensor-based power rating and the component sensor-based power rating as a selected power rating.
