Straight Power 11 550W 80 PLUS Gold Power Supply from be quiet!
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.
Provides Virtually Inaudible Operation
SILENT WINGS 3 FANThe 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.
Higher Cooling Performance
FUNNEL-SHAPED FAN OPENINGThe fan inlet of the Straight Power 11 is funnel-shaped. It causes an increased throughput of air which benefits to a higher cooling performance.
Pushing the Longevity of Components to a Maximum
WIRE-FREE DESIGN INSIDE THE PSUThe 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.
Impressively High Efficiency
80 PLUS® GOLD CERTIFIEDStraight 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.
Compatibility for the Systems of Tomorrow
HIGH-CLASS TECHNOLOGIESThe 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
JAPANESE 105° CAPACITORSOnly the best components are used in Straight Power 11. That is why be quiet! 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.
Utmost Convenience and Compatibility
MODULAR CABLESThanks 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.
