The Corsair CX650 is a reliable 650 W ATX power supply with 80 Plus Bronze certification, ensuring up to 85 percent energy efficiency under typical loads. This non-modular unit features a single +12V rail with 54 A for consistent power distribution to critical components. Designed with a 120 mm quiet fan that automatically adjusts its speed according to thermal conditions, it remains quiet during normal use while providing adequate cooling under load. Built with Japanese capacitors for enhanced durability and long-term reliability, the power supply supports modern graphics cards and processors with comprehensive protection circuits including over-voltage, under-voltage, over-load, and short-circuit protection. The black steel chassis measures 150 mm in depth, 86 mm in height, and 140 mm in width, weighing 1.5 kg for standard ATX case compatibility. Equipped with essential connectors including 1x 24-pin ATX, 1x 8-pin EPS12V, 1x 4+4-pin EPS12V, 2x 6+2-pin PCIe, 6x SATA, and 3x 4-pin peripheral connectors to accommodate various system configurations. Operating with an input voltage of 100-240 V AC and a frequency of 47-63 Hz ensures stable performance across different power grids. The unit achieves efficiencies of 85 percent at 20 percent load, 88 percent at 50 percent load, and 85 percent at 100 percent load while maintaining low ripple and noise levels for clean power delivery to sensitive components. Suitable for mainstream desktop computers that require reliable power supply without modular cable management.
