Be quiet! Straight Power 11 550W ATX24

World Class Quiet and Efficency be quiet Straight Power 11 550W raises the bar for systems that demand virtually inaudible operation without power quality compromises. 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 550W 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 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. 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 550W is certified with 80PLUS Gold efficiency, reaching up to 93%.
