Be Quiet DARK POWER PRO 11 (BN254) product



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 1000W 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
1000 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 confidence
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

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

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
Long service life up to 100,000 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
