Product Information

WORLD CLASS QUIET AND EFFICIENCY

be quiet! Straight Power 11 850W raises the bar for systems that demand virtually inaudible operation without power quality compromises.

  • Virtually inaudible SilentWings® 3 135mm fan
  • Funnel-shaped fan opening of the PSU case for high airflow intake
  • Wire-free inside the PSU on the DC side for enhanced cooling and longevity 
  • Full cable management for maximum build flexibility
  • 80PLUS® Gold efficiency (up to 93%)
  • Powerful multi-GPU support with two PCI-Express connectors
  • Japanese 105°C-rated capacitors ensure stability and reliability
  • ErP and Energy Star 6.1 ready

SILENT WINGS® 3 FAN
Provides virtually inaudible operation
The high-end SilentWings® 3 fan delivers best-of-class airflow yet produces very little noise. This is thanks to its unique, optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor that largely eliminates operational noise, has a super-long life and minimal power consumption.

FUNNEL-SHAPED FAN OPENING
Higher cooling performance
The fan inlet of the Straight Power 11 850W is funnel-shaped. It causes an increased throughput of air which benefits to a higher cooling performance.

WIRE-FREE DESIGN INSIDE THE PSU
Pushing the longevity of components to a maximum
An absolute innovation: The Straight Power 11 850W is wire-free on the DC side inside the PSU body. This results in improved cooling airflow and less signal disturbance, simply because of a lack of wiring, and ultimately pushes the lifetimes of the components to a maximum.

FULLY MODULAR CABLE MANAGEMENT
Utmost convenience and compatibility
Thanks to the fully modular cable management, cables that serve no purpose in the system are left out. For this reason systems always appear very tidy. At the same time installation is performed much more conveniently. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures prevail inside the case.

80PLUS® GOLD CERTIFIED
Impressively high efficiency
Straight Power 11 850W is certified with 80PLUS® Gold efficiency, reaching up to 93%. This gives less power consumption and a cooler and quieter operation. Truly a benefit for any system.

HIGH-CLASS TECHNOLOGIES
Compatibility for the systems of tomorrow
The use of LLC and Synchronous Rectifier (SR) provides very stable operation and enhanced voltage regulation.The PSU is equipped with DC-to-DC conversion for tight voltage regulation even under heavy cross-loading conditions. This ensures reliable operation with the next generation of processors and graphics cards.

JAPANESE 105° CAPACITORS
A testament to high quality
Only the best components are used in Straight Power 11 850W. That is why we have built only high-quality Japanese capacitors into the PSU chassis. They are rated to 105°C, ensuring stability, reliability and a long operating life.
