    New PSU Efficiency Certifications - Cybernetics "ETA" (efficiency) and "LAMBDA" (noise)

      I'll let you read the article, but basically it tests PSUs at hundreds of different load level combinations, not just the 4 80 Plus uses,

      As of right now there are only 40 PSUs in the database, but none of them, even from the giants of Super Flower, Seasonic, FSP, and Enermax, have an A++ efficiency (ETA) score, even on their 80 Plus Titanium units. Each power supply tested is accompanied by a detailed report breakdown, including efficiency performance under more realistic 40°C ambient temperatures. Granted it is extremely difficult to hit all the A+ ETA requirements, but that's the point.
