Feature Details

Energy Efficiency

• 80PLUS^® Platinum certification with up to 94% efficiency
• Saving power means saving money, but it also mean less waste heat, less cooling required, and overall quieter operation
• Standby drain less than 0.10Watts
• Meets Energy Star 6.0 guidelines
• Fulfills the ErP 2014 guidelines
• Zero Load design supports Intel’s Deep Power Down C6 and C7 modes

Virtually Inaudible Operation

• Installed SilentWings^® 3 135mm fan includes a wide array of electronic and mechanical optimizations for best-of-class airflow with very low noise production, including:
  • Unique airflow-optimized fan blade design reduces noise-generating fan turbulence
  • Advanced fluid dynamic bearing with copper core provides for greatly reduced operating noise and super-long life
  • 6-pole fan motor smoothes operation even at very low speeds
  • High quality IC motor controller reduces electrical noise
• PSU case has a large funnel-shaped fan opening that facilitates high airflow intake
• SilentWings^® 3 fan is decoupled from the PSU body with special rubberized ring mount, reducing transmission of vibration and noise
• Dual-layer PSU housing with rubberized sleeve isolates your chassis from PSU noise and vibration, further enhancing silence
• Optimized PSU airflow generates superior cooling at lower fan speeds, reducing turbulence and allowing even quieter operation
• Variable fan speed is optimally governed to strike the best balance between proper cooling and deep quietness
• Up to four case fans can be connected to, and regulated by the PSU, thus reducing overall system noise even further

Engineering

• Advanced full bridge, LLC, Synchronous Rectifier (SR) and DC-to-DC power conversion circuitry design supports unmatched signal stability and unbeatable power efficiency
• Overclocking key allows you to choose between multi-rail operation with four independent 12V-rails and high-performance single-rail operation
• Premiere-quality Japanese capacitors rated to 105°C for maximum reliability and operating life
• Increased output of 12V capacitors to minimize feedback sounds of graphics cards
• Top protection for components against over-currents, over- and under-voltages, short circuits, overheating, overloads and voltage surges on input side
