Be Quiet! 850W Straight Power 11 PSU Modular Fluid Dynamic Fan SLI/XFire 80+ Gold

WORLD CLASS QUIET AND EFFICIENCY

be quiet! Straight Power 11 raises the bar for systems that demand virtually inaudible operation without power quality compromises. 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. The Straight Power 11 has an 80 PLUS Gold efficiency rating of up to 93%, and the Japanese capacitors ensure excellent stability and reliability.

SILENT WINGS 3 FAN

The high-end Silent Wings 3 fan delivers impressive 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 lifespan 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

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

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.

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.
