DARK POWER PRO 11

650W

No Compromise Silence and Performance

Dark Power Pro 11 650W is be quiet!’s most advanced PSU ever. With 650W of continuously available power and an overclocking key that switches between four-rail and single-rail operation, it has sufficient reserves to support any multi-GPU or multi-CPU system you could want to build. be quiet!’s virtually inaudible SilentWings® 3 fan and an unparalleled array of noise-reducing enhancements make it the quietest PSU in its category, perfect for powerful applications that nevertheless need significant quietness. And its full bridge power topology earns it one of the highest power efficiency certification available — 80PLUS® Platinum.

  • 80PLUS® Platinum certification and up to 94% power conversion efficiency
  • Virtually inaudible operation thanks to a broad array of optimizations, including the use of a be quiet! SilentWings® 3 135mm fan
  • SilentWings® 3 fan features an advanced fan frame, an airflow-optimized fan blade, fluid-dynamic bearing with copper core and a high-quality 6-pole motor for less vibration
  • The funnel-shaped fan opening of the PSU case is significant big and allows high airflow intake
  • 650 Watts of continuous power provide intensive power reserves for demanding computing applications
  • Overclocking key allows switchover between quadruple independent 12V-rail mode and high-performance single-rail operation
  • NVIDIA SLI Ready and AMD CrossFireX certifications allow you to build powerful Multi-GPU systems with confidenc
  • Cable management with extra long cable reach simplifies component installation and reduces annoying clutter, increasing airflow and improving cooling in even the largest PC cases
  • Product conception, design and quality control in Germany

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 0.14Watts
  • 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

  • Unmatched signal stability and unbeatable power efficiency thanks to advanced half bridge, LLC, Synchronous Rectifier (SR) and DC-to-DC power conversion circuitry design
  • Overclocking key allows you to choose between multi-rail operation with four independent 12V-rails and high-performance single-rail operation
  • Premiere-quality 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
  • Long service life up to 180,000 hours
  • Full performance during 24/7 operation

Maximum Compatibility and Convenience

  • Supports the latest Intel® and AMD™ processors
  • Compatible with ATX12V 2.4 and EPS12V 2.92 standards
  • Professional modular cable management system with removable cable bundles simplifies component installation, reduces annoying clutter, increases airflow and allows for improved cooling
  • Cable management with 2x P8 connector for better voltage stability for the CPU
  • System supports up to 32 connectors for massive system builds
  • Connectors are compatible with older components as well as those still on the drawing board
  • Sleeved cable lengths up to 120cm are perfect for large PC cases and allow for improved cooling in any size case
  • Individual P4 and P8 plugs support all common mainboard types
  • Five PCIe connectors for powerful multi-GPU configurations (NVIDIA SLI and AMD CrossFireX) up to Quad-GPU
  • Clearly labeled plugs and clever accessories promote simple installation

Outstanding Service and Support
