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 750W 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
- 750 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
- Product conception, design and quality control in Germany
- Advanced, high-resolution gaming and multimedia systems
- Overclocked systems
- Multi-GPU workstations for 3D graphics, photo editing, video editing
- Any application that requires high power with superior quietness
- 80PLUS® Platinum certification with up to 94% efficiency
- Saving power means saving money, but it also means less waste heat, less cooling required, and overall quieter operation
- Standby drain less than 0.15Watts
- 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
- 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
- Seven 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
