Product details

The be quiet! Straight Power 11 Platinum 1000W sets new standards for whisper-quiet systems with outstanding efficiency. It is 80 PLUS Platinum certified and achieves an efficiency of up to 94.1%. This is a significant advantage for any system, as it reduces energy consumption, provides better cooling, and ensures quieter operation.

The high-quality Silent Wings 3 fan is impressively quiet and delivers top-notch airflow. It features an optimized blade design, an advanced fluid dynamic bearing, 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 enhances airflow and leads to improved cooling performance.

This improves air circulation, reduces signal interference by eliminating cables, and increases the longevity of the components. Only the cables that are truly needed are used, resulting in a tidy case, easy installation, and unobstructed airflow, leading to lower system temperatures and overall quieter operation.

Experience the most technologically advanced power supply from be quiet! Full Bridge and Synchronous Rectifier (SR) technologies offer unparalleled signal stability and unbeatable energy efficiency. The DC/DC converter ensures even stronger voltage regulation, even under heavy cross-load conditions, and guarantees reliable operation with the next generation of processors and graphics cards.
