80 Plus Platinum Certified
 
One of the highest efficiency certificates available
Straight Power 11 Platinum 550W is certified with 80 PLUS Platinum efficiency, reaching up to 93,8%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation. The standby drain is below 0.1 watts.
 
 
 
 
 
Silent Wings 3 Fan
 
Provides virtually inaudible operation
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
 
Higher cooling performance
The fan inlet of the Straight Power 11 Platinum 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 Platinum 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
 
Utmost convenience and compatibility
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.
 
 
 
 
 
State-of-the-Art Technologies
 
Rock-steady signal stability and efficiency
Experience the most technologically advanced power supply be quiet! has ever built! Using an advanced full bridge, LLC and Synchronous Rectifier (SR) technology it provides unmatched signal stability and unbeatable power efficiency. The DC-to-DC conversion for tight voltage regulation, even under heavy cross-loading conditions ensures reliable operation for the next generation of processors and graphics cards.
 
 
 
 
 
Japanese 105 Capacitors
 
A testament to high quality
Only the best components are used in Straight Power 11 Platinum 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.
