850W be quiet! Dark Power Pro 11

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 850W 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.

FEATURES

• 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
• 850 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
