Very high operating efficiency
Pure Power 12 M 750W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 92.6%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 12 M 750W is always the correct choice for quiet systems and gaming PCs!
Fulfills all ATX 3.0 specifications
Pure Power 12 M 750W is an ATX 3.0 PSU and comes with both native integration of the 12VHPWR connector for next-generation PCIe 5.0 graphics cards, and PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and the perfect choice for powerful systems of today and the ones to come.
Massive transient loads
Pure Power 12 M offers 750W of continuous power with 2 independent 12V rails. Even if the graphics card demands excessive power for a short time: Pure Power 12 M 750W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.
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.
Rock-solid stability
With its LLC topology Pure Power 12 M 750W 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.
Utmost convenience and compatibility
Thanks to their modularity, all unnecessary cables in the system are left out. Pure Power 12 M 750W 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.
