  2. Power supply unit (computer) - Wikipedia

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

    The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.

  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).

    en.wikipedia.org/wiki/PowerTOP

    PowerTOP is a software utility designed to measure, explain and minimise a computer's electrical power consumption. [1] It was released by Intel in 2007 under the GPLv2 license. It works for Intel, AMD, ARM and UltraSPARC processors.

  6. Computer performance - Wikipedia

    en.wikipedia.org/wiki/Computer_performance

    In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:

  7. Laptop - Wikipedia

    en.wikipedia.org/wiki/Laptop

    A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid.

  8. Desktop computer - Wikipedia

    en.wikipedia.org/wiki/Desktop_computer

    A computer lab with desktop PCs with flat-panel monitors. A desktop computer, often abbreviated as desktop, [1] is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer) due to its size and power requirements.

  9. Processor power dissipation - Wikipedia

    en.wikipedia.org/wiki/Processor_power_dissipation

    Processor manufacturers usually release two power consumption numbers for a CPU: typical thermal power, which is measured under normal load (for instance, AMD's average CPU power) maximum thermal power, which is measured under a worst-case load; For example, the Pentium 4 2.8 GHz has a 68.4 W typical thermal power and 85 W maximum thermal power.
