be quiet! Pure Power 12 M power supply unit 850 W 20+4 pin ATX ATX Black

EXCEPTIONAL QUIET, SUPERIOR FEATURESPure Power 12 M 850W is ATX 3.0 compliant and PCIe 5.0 compatible and offers peerless dependability with best-in-class features. Pure Power 12 M 850W offers the best combination of features with outstanding compatibility.80 PLUS® GOLD CERTIFIEDVery high operating efficiencyPure Power 12 M 850W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 93.2%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 12 M 850W is always the correct choice for quiet systems and gaming PCs!FUTURE-PROOF YOUR SYSTEMFulfills all ATX 3.0 specificationsPure Power 12 M 850W 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 present high-end systems and the ones to come.THE NEW STANDARD OF POWERFor massive transient loadsPure Power 12 M offers 850W of continuous power with 2 independent 12V rails. Even if the graphics card demands excessive power for a short time: Pure Power 12 M 850W 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 OPERATIONAchieved with a silence-optimized be quiet! fanThe 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-classquiet functionality. HIGH-CLASS TECHNOLOGIESRock-solid stabilityWith its LLC topology Pure Power 12 M 850W 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 CABLESUtmost convenience and compatibilityThanks to their modularity, all unnecessary cables in the system are left out. Pure Power 12 M 850W 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.
