80 Plus Certification
80 Plus® is a voluntary certification program that measures the energy efficiency of power supplies in computers and servers. To be certified, a power supply must be at least 80% efficient at 20%, 50%, and 100% of rated load—with a true power factor of 0.9 or greater. Power supplies with an 80 Plus rating waste less electricity and are cooler than less efficient units, resulting in lower energy bills and improved system reliability.
