The New Standard of Power
For massive transient loads
Pure Power 12 M offers 550W of continuous power with 2 independent 12V rails. Even if the graphics card demands excessive power for a short time: Pure Power 12 M 550W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.

Unprecedented Silent Operation
Achieved with a silence-optimized be quiet! fan
The exceptionally silent 120mm be quiet! fan is temperature-controlled to strike the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, enabling best-in-class
quiet functionality.

High-Class Technologies
Rock-solid stability
With its LLC topology Pure Power 12 M 550W provides a best-in-class voltage regulation and efficiency. That makes it perfect for building or upgrading very quiet systems as well as gaming and media creation PCs.
 
Modular Cables
Utmost convenience and compatibility
Thanks to their modularity, all unnecessary cables in the system are left out. Pure Power 12 M 550W simplifies cable management and routing for a tidy-looking system. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures inside the case.
