INTRODUCTION
Equipped with a new generation of design and components, the Element ST50EF continues SilverStone's stride toward more efficient power supplies. With higher than 80% efficiency across all loading conditions (from 20% to 100%), the ST50EF 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 power for dual core/dual video card processing and silence are the main priorities, the Element st50ef-plus is for you.

  
 
SPECIAL FEATURES

  • Efficiency over 80% across all loading conditions (20% to 100%)
  • Dual +12V rails for advanced systems
  • Dual PCI-E connectors (Multi-GPU ready)
  • Industry-leading silent running 120mm fan
  • Support for ATX 12V 2.2
  • Active PFC
