80 Plus® is an iniciative to promote greater energy efficiency in the power supplies of computer systems. The power supply is the device that provides energy to the computer, and converts the alternating current into direct current, and is of critical importance to a computer system.
The 80 PLUS certification specifies that the efficiency of the power supply is at least 80%. In other words, that the energy converted into heat is 20% or less of the total energy consumed.
There are several types of 80 PLUS certifications; 80 Plus, Bronze, Silver, Gold, Platinum and Titanium. TTL brand systems, manufactured by TEKNOSERVICE, range from the Gold rating to 80 PLUS, which means that the energy efficiency of the power supply is up to 87%.
