Launched by Ecos Consulting in 2004, 80 Plus is a certification for power supply units in computers created to promote the conservation of energy.
80 Plus stipulates that products must be at least 80% energy efficient at 20, 50 and 100% of their rated load. In short, units carrying this certification can only waste up to a maximum of 20% of their electrical energy as heat at these specified load levels.
