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. History EPRI (Electric Power Research) and Ecos Consulting (promoter of the brand) develop the Generalized Internal Power Supply Efficiency Test Protocol for desktop derived multi-output power supplies. March 2004: the 80 Plus idea was presented as an initiative at the ACEEE Market Transformation Symposium. February 2005: the first market-ready power supply was created by Seasonic. 2006: Energy Star added 80 Plus requirements to their then-upcoming (in effect since July 2007) Energy Star 4.0 computer specifications. November and February 2006: HP and Dell certify their PSUs to the 80 Plus specification. 20 July 2007: Energy Star Computer Specification 4.0 goes into effect. The specification includes 80 Plus power supply efficiency levels for desktop computers. December 2007: over 200 PSUs on the market are 80 Plus certified and it is becoming the market standard. First-quarter 2008: standards revised to add Bronze, Silver, and Gold higher efficiency level certifications. October 2009: added specification for the Platinum efficiency level. February 2012: Dell and Delta Electronics working together were able to achieve world-first 80 Plus Titanium server power supply. Efficiency level certifications
