Dark Power Pro 11 550W


Legendary Silence, Cutting Edge Performance

It is a fact of the modern world that high technology requires constant refinement and unending improvement — and that is even truer for those who would be leaders. Dark Power Pro power supplies are renowned as the world’s quietest and most efficient high-performance PSUs. The Dark Power Pro 11 550W model takes that a step further with a power conversion topology that delivers 80PLUS® Platinum performance, add to that an unparalleled array of enhancements that augment this unit’s compatibility, convenience of use, reliability, and safety, and the result is the most technologically-advanced power supply be quiet! has ever built.

  • 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
  • 550 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
  • 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

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
be quiet!



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
  • Clearly labeled plugs and clever accessories promote simple installation
