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. 80 Plus - Wikipedia

   en.wikipedia.org/wiki/80_Plus

   80 Plus (trademarked 80 PLUS) is a voluntary certification program launched in 2004, intended to promote efficient energy use in computer power supply units (PSUs). Certification is acquirable for products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load.

4. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

5. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Utility frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.

   PC Power and Cooling (stylized as PC Power & Cooling), a subsidiary of FirePower Technology, is an American manufacturer of computer power supplies based in Carlsbad, California. The company was established by Doug Dodson in 1985. In 2007, the company was acquired by OCZ Technology. In 2014, FirePower Technology acquired OCZ Technology Group's ...

7. 16-pin 12VHPWR connector - Wikipedia

   en.wikipedia.org/wiki/16-Pin_12vHPWR_connector

   The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors for GPUs. The primary aim was to cater to the increasing power requirements of high-performance GPUs.
