Overview


World Class Quiet and Efficiency

be quiet! Straight Power 11 750W raises the bar for systems that demand virtually inaudible operation without power quality compromises. This PSU is clearly the best choice for super silent systems.




At-a-glance


  • 80PLUS® Gold certification with an efficiency of up to 93%

  • Advanced stability and voltage regulation thanks to LLC, SR and DC-to-DC

  • An absolute innovation: The Straight Power 11 750 W 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.

  • Big funnel-shaped fan opening of the PSU case for high airflow intake

  • ErP and Energy Star 6.1 ready

  • Four high-performance 12V-rails

  • Full cable management for maximum build flexibility

  • Japanese 105°C-rated capacitors ensure stability and reliability

  • Only the best components are used in Straight Power 11 750 W . 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.

  • Power signal stability unmatched in its class

  • Powerful multi-GPU support with two PCI-Express connectors

  • Product conception, design and quality control in Germany

  • Straight Power 11 750 W is certified with 80 PLUS Gold efficiency, reaching up to 93%. This gives less power consumption and a cooler and quieter operation. Truly a benefit for any system.

  • Thanks to the modular cables, all 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.

  • The fan inlet of the Straight Power 11 750 W is funnel-shaped. It causes an increased throughput of air which benefits to a higher cooling performance.

  • The high-end Silent Wings 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.

  • 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.

  • Virtually inaudible operation thanks to a SilentWings® 3 135mm fan

  • Wire-free on the DC side inside the PSU for enhanced cooling and longevity
