World Class Quiet and Efficiency

Provides virtually inaudible operation

01

02

03

Silent Wings 3 Fan

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.

Funnel-Shaped Fan Opening

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

Wire-Free Design Inside the PSU

An absolute innovation: The Straight Power 11 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.

Compatibility for the systems of tomorrow

04

05

06

Fully Modular Cable Management

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.

80 PLUS Gold Certified

Straight Power 11 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.

High Class Technologies

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.

A testament to high quality

07

Japanese 105° Capacitors

Only the best components are used in Straight Power 11 450W. 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

Be Quiet 750w straight Gold
Great PSU.. dumb quiet I installed it in my Montech Air X case. At idle I don't hear and coil wind what's so ever.On full load I hear my GPU fans more then anything. This bequiet PSU replaced my thermal take 750 smart fan which was getting loud under full load. As for the cables supplied that comes with this unit. I prefer ribbon style cables mainly for the look the 24 pin and 8Pin CPU plug. I cant really complain as for ease of cable management. The cables are nice and stiff so I recommend before installing the ones you need give them a little work out so you minimize any unwanted damage to the parts your gonna be installing them too.I recommend this PSU for anyone attempting a quiet PC build.
