Introduction

Since its inception in 2004, the 80 PLUS initiative has played a crucial role in driving improvements in power supply efficiency and sustainability. The program initially focused on achieving 80% efficiency at three load levels, which significantly surpassed existing efficiency standards. Over the years, 80 PLUS has expanded its specifications and gained widespread industry recognition. As a result, ENERGY STAR® and the European Union (EU) Energy-related Products Directive (ErP) have adopted its standards.
