The be quiet! Straight Power 11 sets standards for whisper-quiet systems with outstanding efficiency. This is a real advantage for any system, as it reduces energy consumption, improves cooling, and achieves quieter operation. The Silent Wings 3 fan is impressively quiet and delivers top-notch airflow. It is equipped with many features, such as an airflow-optimized design of the fan blades, advanced fluid-dynamic bearings, and a 6-pole motor, which ensure minimal vibrations, longevity, and low power consumption. The funnel-shaped design of the fan inlet in the power supply housing increases airflow, ultimately leading to improved cooling performance. The Straight Power 11 is internally cable-free on the DC side of the power supply. This enhances air circulation, reduces signal interference due to the absence of wiring, and maximizes the longevity of the components. Only the cables that are truly needed are used. The advantage: a tidy case, easy installation, and uninterrupted airflow, resulting in lower system temperatures and an overall quieter operation. Experience the power supply from be quiet!. The Full Bridge, LLC, and Synchronous Rectifier (SR) technologies provide unparalleled signal stability and unbeatable energy efficiency. The DC/DC converter ensures even stronger voltage regulation - even under heavy cross-loads. This guarantees reliable operation, even with the next generation of processors and graphics cards. Only high-quality components are used in the Straight Power 11, which is why only premium Japanese capacitors are installed. They are designed for operating temperatures up to 105°C and ensure reliability as well as a long lifespan.
