  2. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    For example, a 900-watt power supply with the 80 Plus Silver efficiency rating (which means that such a power supply is designed to be at least 85% efficient for loads above 180 W) may only be 73% efficient when the load is lower than 100 W, which is a typical idle power for a desktop computer. Thus, for a 100 W load, losses for this supply ...

  3. Performance per watt - Wikipedia

    en.wikipedia.org/wiki/Performance_per_watt

    The power measurement is often the average power used while running the benchmark, but other measures of power usage may be employed (e.g. peak power, idle power). For example, the early UNIVAC I computer performed approximately 0.015 operations per watt-second (performing 1,905 operations per second (OPS), while consuming 125 kW).

    Power gating: [7] [8] Entire functional units of the processor are disconnected from the power supply, thus consuming effectively zero power. Multiple voltage domains: [ 7 ] Different portions of the chip are supplied from different voltage regulators, such that each can be individually controlled for scaling or gating of the power supply.
