ABSTRACT:
Embodiments of a system for regulating an efficiency of a power supply in a computer system are described. During operation, the system measures an output load of the power supply using one or more telemetry monitors in the computer system. Then, the system determines if an efficiency of the power supply corresponding to the measured output load is within a predetermined range that includes an optimal efficiency of the power supply. If the efficiency is outside of the predetermined range, the system performs remedial action so that the power supply operates at an adjusted efficiency that falls within the predetermined range.
