About the Be Quiet! Straight Power 11 850W Power Supply Unit

Silent Wings 3

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.

Higher Cooling Performance

The fan inlet of the Be Quiet! Straight Power 11 850W is funnel-shaped. It causes an increased throughput of air which benefits to a higher cooling performance.

Wire-free Design

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.

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.

Japanese 105° Capacitors

Only the best components are used in Be Quiet! 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.
