bequiet! Power Supplies BN344 Editorial Review
### Editorial Review The Be Quiet! Pure Power 12 M 850W modular power supply has been universally well-received by customers, particularly those building or upgrading their gaming systems. Many users report a significant improvement in the noise levels of their systems, especially for high-end graphics cards like the RTX 5080, where issues like coil whine are effectively mitigated. The native 12VHPWR cable (PCIe 5.1) eliminates the need for cumbersome adapters, adding to user convenience and reducing cable clutter. Installation experiences have been predominantly positive, with many customers appreciating the well-thought-out design and cable lengths that do not hinder installation. The flat, flexible cables make routing simple, allowing for a neat appearance even in tighter spaces. Users with an eye for aesthetics particularly commend the all-black cables, which blend seamlessly into their setups. In operation, the power supply lives up to its name, remaining nearly silent during use, even under heavy load during extended gaming sessions. The overall reliability and performance have also been highlighted, with many customers reporting stable operation without voltage fluctuations or stability issues. However, there are some critiques concerning the rigidity of the cables, which may pose challenges during installation for some users. While functional, they could be more flexible, improving ease of cable management. Despite this minor inconvenience, the product’s quality, performance, and overall silence have led many to offer strong recommendations, declaring it a great investment for both current and future hardware setups. In summary, the Be Quiet! Pure Power 12 M 850W is a robust, efficient, and quiet power supply that successfully fulfills the needs of modern gaming systems, making it a top contender in its category. ### Pros and Cons **
