Be Quiet!, the market leader in PC power supplies in Germany for twelve consecutive years, announces its new mainstream power supply series: Pure Power 11. The series consists of six models with fixed cables ranging from 300 to 700 watts and four models with modular cables ranging from 400 to 700 watts. Previously, Pure Power 10 introduced DC-to-DC transformation to be quiet!'s best selling power supply series, improving crossload performance and voltage regulation on its minor rails. Pure Power 11 expands on this proven technology by upgrading both passive and active components, enabling higher efficiency of up to 92% with 80 PLUS Gold certification, and leading to less heat generation and quieter operation. Manufacturer warranty has also been increased from three to five years.
Pure Power 11's standout technology includes a DC-to-DC convertor, significantly improving both voltage quality on the 3.3V and 5V rails as well as crossload stability. The so-called "Active Clamp + SR" topology contributes to high efficiency ratings and stability. Pure Power 11 power supplies rated 400 watts or higher are 80 PLUS Gold certified, peaking at 92% efficiency. The models with 300 or 350 watt output are 80 PLUS Bronze certified. Up to 96% of the PSU's total power goes to the 12V rails powering the PC's critical components.

Silent operation with a proven cooling fan
Along with reduced motor and bearing noise, Pure Power 11's power supply fan is just as reliable as its predecessor's. The fan curve is automatically fine-tuned using an independent temperature sensor to control the airflow-optimized fan blades. Thanks to an overall increased efficiency the fan speed is reduced, resulting in a low noise level of no more than 25.9 dB(A).
