Pure Power 12 M 550W is ATX 3.0 compliant and PCIe 5.0 compatible and offers peerless dependability with best-in-class features. Pure Power 12 M 550W offers the best combination of features with outstanding compatibility.
Pure Power 12 M 550W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 92.8%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 12 M 550W is always the correct choice for quiet systems and gaming PCs!
Pure Power 12 M 550W 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.
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.
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.
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.
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.
“Ever since the first Pure Power, uncountable amounts of it have found their way into the PCs – and most likely hearts – of users worldwide.”
