80Plus Certification
The 80PLUS test protocol was developed jointly by Ecos Plug Load Solutions and the Electric Power
Research Institute (EPRI) in 2003, with the program being formally launched in 2004.
The 80 PLUS performance specification requires power supplies in servers to be 80% or greater energy
efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an
80 PLUS certified power supply substantially more efficient than typical power supplies found in many
other electrical devices.
