80 PLUS
80 PLUS is a North American initiative to promote PC power supplies that have an efficiency of 80% or higher. The initiative also lists compliant devices and makes the corresponding measurement protocols available on the Internet.
conditions
For an “80 PLUS” certification, the initiative demands that power supplies for desktop computers and servers achieve an efficiency of at least 80% at load points of 20%, 50% and 100%. In addition, certain demands are made on the power factor of the PFC . For the higher certifications "80 PLUS Bronze", "80 PLUS Silver", "80 PLUS Gold", "80 PLUS Platinum" and "80 PLUS Titanium", the efficiency requirements have been gradually increased, with a focus on the frequently used load range of 50%.

history
- Ecos & EPRI developed the Generalized Internal Power Supply Efficiency Test Protocol (general test protocol for internal power supplies) for PC power supplies with multiple outputs.
- In March 2004, the "80-PLUS" idea from an initiative was presented at the ACEEE Market Transformation Symposium .
- In February 2005 the first market-ready "80-PLUS" certified power supply from Sea Sonic was presented.
- In 2006, Energy Star added the “80 PLUS” requirements to its future Energy Star 4.0 computer specifications.
- In November and February 2006, HP and Dell will certify their power supplies according to the "80-PLUS" specifications.
- On July 20, 2007, the Energy Star Computer Specification 4.0 came into force. The specification includes the "80-PLUS" requirements for desktop computers.
In December 2007, more than 200 power supplies were already "80-PLUS" -certified on the market and thus the future standard.
In the first quarter of 2008 the standards were revised in order to certify higher levels of efficiency with bronze, silver and gold. While models certified with “bronze” followed quite soon, models with the two higher certifications will not appear until the middle to the end of 2009. The “silver” level is partially skipped by the manufacturers or only used for cheaper models. The “80 PLUS Platinum” stage will follow at the end of 2009, previously also partly discussed as “90 PLUS”, which stipulates an efficiency of over 90% and even 94% at medium load. The same applies initially only to server power supplies; In 2010 a slightly modified version for desktop systems followed.
As of Easter 2010, there were around 350 certified models available in Europe, around half of which were "Bronze" or higher certified. The number of certified power supplies, many of which are just concept studies, has now exceeded 2000.
In mid-2011 (June 10, 2011) the number of certified power supplies available in Europe reached over 550. The two lowest levels (standard and bronze) each make up 200 models; Silver and gold share the other 150. Only 40 models with a platinum certification are in stores at this point in time. The total number of certified models (including concept studies) is almost 3000 with a similar distribution.
criticism
The power supply units are measured in a laboratory environment with an air temperature of 23 ° C. However, due to the waste heat from the computer or a warmer outside temperature in summer, power supplies are operated at higher temperatures for many users. However, higher temperatures have a negative effect on the efficiency of the power supply unit, as the efficiency of the semiconductors built into it decreases at higher temperatures.
In addition, there is the possibility that the efficiency measured in the 80-PLUS measuring laboratory will be higher than with freely commercially available copies, for example if the power supply manufacturer replaces individual components in later batches for more inefficient ones or so-called "golden samples", i.e. especially for the Sends specimens manufactured by a measuring laboratory that are not commercially available for measurement.
