Semi-modular 650 W ATX unit with 80 Plus Bronze efficiency, a 120 mm sleeve-bearing fan, and cables for two 6+2-pin PCIe plus six SATA devices
Model CX-M Series (650W)
The Corsair CX650M is a semi-modular power supply rated at 650 W with 80 Plus Bronze certification. It uses a single +12 V rail and a 120 mm sleeve-bearing fan. The unit supports ATX12V and EPS12V standards and includes two 6+2-pin PCIe connectors for graphics cards.
Verify that your case accepts a unit up to 140 mm long. Confirm your motherboard uses a 20+4-pin main connector and an EPS12V CPU connector. Ensure the two PCIe connectors and six SATA power plugs match your component count before ordering.
This supply fits mainstream desktop upgrades and basic system builds where 650 W covers the hardware. Builds with multiple high-power graphics cards or extreme overclocking should look at higher-wattage units with fully modular cabling.

Other versions of this model
The semi-modular design includes a fixed 20+4 pin ATX connector plus detachable cables for two 6+2 pin PCIe and six SATA power connections; no extra cables are required for standard builds.
At 650 W with a single +12 V rail rated at 54 A it suits mid-range CPUs and single-GPU systems; select a higher-wattage model only if your total system draw exceeds this capacity.
Up to 85 % efficiency at typical loads means less waste heat and lower electricity cost; the unit meets 80 PLUS Bronze certification across 100-240 V input range.
