Things to Consider

This PSU is non-modular; all cables are fixed. While the main cables are sufficient for typical builds, enthusiasts who prefer custom cable routing may want a modular unit. The 650W rating is insufficient for top-tier components like an Intel Core i9-14900K plus RTX 4090; users planning such a configuration should step up to a 750W or higher model. Competitors include the Corsair RM650x and Seasonic Focus Gold series. The be quiet! stands out with its outstanding quietness and long 10-year warranty, making it the preferred choice for silent operation above all else.
