Be Quiet! 650W Straight Power 11 PSU, Fully Modular, Fluid Dynamic Fan, SLI/XFire, 80 Gold UK Plug

World Class Quiet and Efficency be quiet! Straight Power 11 650W 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 four PCI-Express connectors Japanese 105°C-rated capacitors ensure stability and reliability ErP and Energy Star 61 ready 5-year manufacturer’s warranty 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 650W 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 650W 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 650W 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 regulationThe 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 650W 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   Description Specification Series Be Quiet!
