"(Corsair) announced today that it has been awarded 80 PLUS Certification across the entire Corsair line of Power Supply Units (PSUs), including the award winning modular HX Series, powerful TX Series and value-performance VX Series. More Efficient, Same Performance.
80 PLUS Certification is the gold standard for power supply energy efficiency. The 80 PLUS specification requires computer and server PSUs to be at least 80 percent efficient at 20 percent, 50 percent and 100 percent rated load, ultimately improving computer stability and saving money on electricity bills. In addition, there are also performance benefits, such as reduced heat output which increases system reliability and minimizes the need for loud, high rpm cooling fans."
