Forecasting failure of power supply in a data center

An apparatus comprising:

• a power supply and actuarial circuitry in communication with said power supply, said power supply comprising first and second components, wherein said actuarial circuitry is configured to forecast life expectancy of said power supply based at least in part on real-time measurements of operational parameters of said first and second components, wherein said actuarial circuitry is configured to receive a capacitor data-stream and a fan data-stream from said power supply, wherein said first and second components of said power supply having an electrolytic capacitor and a fan, respectively, wherein said actuarial circuitry comprises a real-time fan-mortality forecasting circuit that receives a stochastic fan model and a real-time capacitor-mortality forecasting circuit that receives a stochastic capacitor model, wherein, based on outputs of said real-time fan-mortality forecasting circuit and said real-time capacitor-mortality forecasting circuit, said actuarial circuitry outputs a plurality of voltages selected from the group consisting of a first voltage and a second voltage, said plurality of voltages forming a pattern that is indicative of a power-supply life expectancy that serves as a basis for scheduling replacement of said power supply.
