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 ...
Between 2020 and 2023, there was a worldwide chip shortage affecting more than 169 industries, [1] which led to major price increases, long queues, and reselling among consumers and manufacturers for automobiles, graphics cards, video game consoles, computers, household appliances, and other consumer electronics that require integrated circuits (commonly called "chips").
The ATX specification requires that the power-good signal ("PWR_OK") go high no sooner than 100 ms after the power rails have stabilized, and remain high for 16 ms after loss of AC power, and fall (to less than 0.4 V) at least 1 ms before the power rails fall out of specification (to 95% of their nominal value).
Supply on Jan. 30 was critically low because on top of Hamakua Energy's reduced output, three generation units at other power plants tripped offline, including two that normally generate 32 ...
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.

An integrated power supply is one that shares a common printed circuit board with its load. 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 ...
Prices rose an average of 2.4 percent a year between 1990 and the end of 2019, and inflation coming out of the Great Recession of 2007-2009 proved to be tepid at best despite ultra-low interest rates.
