The RB-650B hits the sweet spot of headroom and value for mid-range gaming and creator builds. The 650W output comfortably drives a modern six- or eight-core CPU paired with a mainstream graphics card, and the ATX 3.1 design with a native 12V-2x6 cable means it is ready for current-generation GPUs and their transient power spikes out of the box.
A semi-modular layout keeps the core 24-pin, CPU EPS and PCIe cables attached for dependable delivery while letting you add only the SATA and peripheral cables your build actually uses. Built-in velcro straps on three sides help you bundle cables cleanly, and the 135mm temperature-controlled fan stays quiet until the load calls for more airflow.
