be quiet! recently announced a new series of its PurePower series, the Pure Power 11 FM is a fully modular version of the Pure Power 11, available in 550, 650, and 750 watts and aimed at mainstream computer users who appreciate the versatility of modular cables and 80 PLUS® Gold efficiency up to 93.9 percent. 

Pure Power 11 FM: Mainstream power supply goes fully modular

Pure Power stands for peerless dependability and a comprehensive feature set at a competitive price point. The Pure Power 11 FM series is no exception: by exclusively using fully modular instead of fixed cables, only cables that serve a purpose are installed, resulting in a smoother airflow, lower temperatures, and easier handling inside the case. Pure Power 11 FM comes equipped with black flat cables for all common connections and a black sleeved 20+4-pin ATX power cable. With two independent 12V rails for signal stability and up to four PCI-Express connectors (two for the 550W model), Pure Power 11 FM is fully suited for silent PC configurations, workstations or even gaming systems with a powerful graphics card.

80 PLUS® Gold efficiency and improved topology

Pure Power 11 FM is 80 PLUS® Gold certified with an efficiency rating of up to 93.9 percent, a truly outstanding level for this PSU class. The most compelling benefits of this high efficiency are lower power consumption, lower electricity costs and a cooler, quieter operation. Pure Power 11 FM is equipped with LLC + SR + DC/DC technology for advanced stability and voltage regulation. Cooling is achieved with a silence-optimized 120mm be quiet! fan with airflow-optimized fan blades, enabling the extraordinarily silent operation that be quiet! is famous for. As usual, all modern protection circuits (including UVP, OVP, SCP, OPP, OCP, and OTP) are integrated. be quiet! offers a 5-year manufacturer’s warranty on Pure Power 11 FM.

The retail prices of the PurePower 11 FM are

• 550W €89.90 $89.90 £79.99
• 650W €99.90 $99.90 £89.99
• 750W €114.90 $114.90 £105.99

Pure Power stands for peerless dependability and best-in-class features at a competitive price point. Pure Power 11 FM is the latest addition to this series: ‘FM’ stands for ‘Fully Modular’, which means that all cables that serve no purpose in the system are left out. This results in a smoother airflow, lower temperatures and easier handling inside the case.

Pure Power 11 FM is 80 PLUS® Gold certified with an efficiency rating of up to 93.9%, a truly outstanding level for this class of PSU. The most compelling benefits of this high efficiency are the lower power consumption and consequently lower costs and a cooler, quieter operation. Unlike other Pure Power 11 models which feature Active Clamp, Synchronous Rectifier (SR) and DC-to- DC technology, the Pure Power 11 FM series is equipped with LLC + SR + DC/DC technology for advanced stability and voltage regulation. Cooling is achieved with a silence-optimized 120mm be quiet! fan with airflow-optimized fan blades, enabling best-in-class quiet functionality.

Two independent 12V rails for signal stability and four PCI-Express connectors make Pure Power 11 FM an extremely versatile mainstream power supply, best suited for silent PC configurations, powerful gaming- or workstations, or even systems with an overclocked high-end GPU.

All Pure Power 11 FM models are 80 PLUS Gold certified and feature efficiency up to 93.9% at 230 volts. High efficiency means monetary savings, reduced heat waste, and an overall quieter operation. Additionally, Pure Power 11 FM models have active PFC with a power factor up to 0.99 and are ErP compliant with standby power drain below 0.14 watts.

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.

Pure Power 11 FM offers 750W of continuous power with two independent 12V rails for signal stability and four PCI express connectors. It is suited to very quiet systems, for upgrading or building multimedia, gaming or systems with an overclocked high-end GPU. Whether you are building a very quiet system or gaming system: Pure Power 11 FM 750W is always the correct choice!

Pure Power 11 FM uses a high-quality 120mm be quiet! fan, thermally controlled and optimally designed to strike the best balance between proper cooling and exceptional quietness. Airflow- optimized fan blades reduce turbulence, allowing for a best-of-class quiet operation and airflow.

Pure Power 11 FM makes use of a superior topology for power supplies. “Half Bridge + LLC + SR (Synchronous Rectifier) + DC-to-DC” is a topology generation that uses IC controllers instead of older style passive components. Two of these chips constantly monitor ingoing and outgoing voltage and adjust the parameters of vital components to the respective load situation. The power supply will always achieve the best possible efficiency at maximum stability for any load. be quiet! uses DC-to- DC technology to generate 3.3V and 5V voltages of the minor rails for its Pure Power 11 FM series. This means the minor voltages are directly generated from the 12V rails, improving the already satisfying voltage regulation and crossload characteristics.
