Abstract
A method for power supply predictive failure detection is disclosed. The method includes measuring, during a time interval, input power and output power for each of a plurality of loads of a power supply. The method includes calculating, for each of the plurality of loads, a power supply efficiency, each power supply efficiency calculated using the input power and output power measured for the load. The method includes comparing, for the time interval, a calculated power supply efficiency at a load of the plurality of loads with a baseline power supply efficiency of the power supply at a corresponding load. The method includes transmitting an alert in response to determining, based on the comparing, that a difference between a calculated power supply efficiency and a corresponding baseline power supply efficiency is above an efficiency threshold.
