Overview
Ultimate silence for exceptional efficiency
The be quiet! Straight Power 11 modular power supply offers quiet operation without compromising on quality. It is 80PLUS Gold certified and offers excellent energy efficiency. An ideal choice for quiet configurations, multi-GPU configurations, multimedia systems and systems for 3D photo/video applications.
100% modular cable managementThanks to fully modular cable management, cables that are not needed in the system are left out. As a result, the system always appears very tidy. Due to the less cluttered layout of the system, the air flow is more fluid, which means less noise and heat inside the housing. In addition, installation is much easier. |

PERFECT
Very well made product.
Super quiet!
With a fan of the same brand on an i78700K, and a Fractal Design case, you can hardly hear anything in basic operation.
Nothing to say about the total modularity.Review automatically translated
