Product Overview

World Class Quiet and Efficiency

be quiet! Straight Power 11 550W raises the bar for systems that demand virtually inaudible operation without power quality compromises.


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 550W 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 550W 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.


Modular Cables

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.


80 PLUS® Gold Certified

Straight Power 11 550W 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.


Japanese 105° Capacitors

Only the best components are used in Straight Power 11 550W. 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.
