650W. CYBENETICS BRONZE. ATX 3.1. PCIe 5.1. SEMI-MODULAR.
CORSAIR CX650M ATX 3.1 PCIe 5.1 650W Semi-Modular Power Supply — Black
The CORSAIR CX650M delivers reliable 650W power for modern gaming and desktop systems with a practical semi-modular cable design. Its ATX 3.1 architecture and PCIe 5.1 readiness add support for current-generation power requirements, including a native 12V-2x6 GPU cable rated up to 450W.
A compact 140mm-long chassis and low-noise 120mm fan make installation easy in a wide range of ATX cases, while Cybenetics Bronze efficiency, LLC topology with DC-to-DC conversion, 105°C-rated capacitors, and a 7-year warranty provide a solid foundation for mainstream gaming builds.
