Detecting an imminent failure of a power supply. An internal computerized component periodically reads a set of measurements from one or more sensors affixed to a power supply. The internal computerized component and power supply may reside in a variety of different technical contexts. The internal computerized component analyzes the set of measurements using, at least in part, a weighted set of factors, to detect the imminent failure in the power supply. The weighted set of factors may be updated or revised over time and may be specifically tailored for use with specific types of power supplies.
