"Power supplies who have an efficiency starting from 80% will get the standard certificate. For those who can manage to reach an efficiency starting from 82% and at least 85% will get the Bronze award. And then there is also the until now almost impossible to reach Silver award that needs at least an efficiency starting from 85% and up to a minimum of 90%! And until now it's still an utopia that a power supply reaches the Gold award with an incredible efficiency starting from 87% and up 90%.
Till now only Dell and NXP have achieved to reach 80 PLUS Silver with their 255W and 270W power supplies. But today Cooler Master is the first one that manages to achieve with a power supply above 300W. Where most power supply manufactures still have trouble reaching the Bronzed award with power supplies over 650W, Cooler Master manages to reach Silver with nothing less than 900W!"
