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. 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.

   Between 1986 and 1987, the company sold 1,000 Silencers and 5,000 Turbo-Cools. [4] The lowest-end entries in the line then were rated for between 150 and 200 watts. [2] [3] In September 2005, the company introduced the first PC power supply rated for 1000 watts. [5] [6] In around 1992, PC Power and Cooling relocated to Carlsbad, California, [7 ...

   With an output of 3,600 watts, it can handle multiple appliances, and you can bump the output to 4,500 watts with its built in X-Boost technology if you need more power.

8. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are ...
