The term "80-plus" typically refers to an efficiency certification for computer power supply units (PSUs). It measures the efficiency of a PSU in converting electrical power from the wall socket into usable power for the computer components.
The etymology of "80-plus" comes from the certification itself. The name "80-plus" originates from the initial requirement set by the 80 PLUS organization, a voluntary certification program created by Ecos Consulting in the early 2000s. The certification aimed to encourage more energy-efficient PSUs in order to reduce wasted electricity and decrease environmental impact.
The "80" in "80-plus" refers to the minimum efficiency level that a PSU should achieve across various load conditions. Originally, PSUs had to achieve at least 80% efficiency at 20%, 50%, and 100% of their maximum rated power output.
