After last month Cooler Master won the first ever 80 PLUS Silver certificate, Dell today in his turn announced that it has become the first to achieve 80 PLUS Gold-certification for a server power supply. The 80 PLUS certification enables manufacturers and customers to compare and contrast power supplies based on established criteria from Energy Star and the Climate Savers Computing Initiative. Dell's new 80 PLUS Gold power supply meets July 2009 Climate Savers targets for servers more than a year ahead of schedule, which require 92 percent minimum efficiency for the power supply unit at 50 percent of rated output. Earlier this month, Dell also became the first Tier-1 computer manufacturer to achieve 80 PLUS Silver-certification for its client desktops.
