Model No. ST40EF
   
 

INTRODUCTION
Equipped with a new generation of design and components, the Element ST40EF continues SilverStone's stride toward more efficient power supplies. With higher than 80% efficiency across all loading conditions (from 20% to 100%), the ST40EF produces less wasted heat than typical power supplies and allows the included 120mm fan to operate at minimal speeds, ensuring silent operation for nearly all applications. This stable output and efficient characteristics are packed inside an environmentally-friendly casing that is compatible with nearly any ATX enclosures on the market. If strong and silence are the main priorities, the Element ST40EF is for you.
