2. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...

3. DC connector - Wikipedia

   en.wikipedia.org/wiki/DC_connector

   Some common DC power connectors. A DC connector (or DC plug, for one common type) is an electrical connector that supplies direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent ...

4. Power supply unit (computer) - Wikipedia

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

   For a 75% efficient power supply to produce 75 W of DC output it would require 100 W of AC input and dissipate the remaining 25 W in heat. Higher-quality power supplies can be over 80% efficient; as a result, energy-efficient PSUs waste less energy in heat and require less airflow to cool, resulting in quieter operation.

6. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power converters include simple devices such as transformers , and more complex ones like resonant converters .

7. Coaxial power connector - Wikipedia

   en.wikipedia.org/wiki/Coaxial_power_connector

   Common DC power connectors. A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity. Also known as barrel connectors, concentric barrel connectors or tip connectors, these small cylindrical connectors come in an enormous variety of sizes.
