    CX-M includes 650W and 750W power supplies, which provides up to 450W and 600W of GPU power through a single cable. That’s more than enough power for the RTX 5070 and 5070 Ti, as well as the RTX 4070 and 4080 lineups.

    Includes a 12V-2x6 cable for next-gen GPUs as well as cables for PCIe devices and SATA, so it covers all the bases for connectivity.

  • Compact Design

    It features a compact 140mm length design for an ATX PSU, ensuring it’ll easily fit in any ATX chassis.

  • 120mm Low-Noise Fan

    Runs cool and quiet with a near-silent 120mm fan that spins silently under low and medium loads, so unless you’re running at full power, you’ll never even know it’s there.

  • Cybenetics Bronze Efficiency

    Certified to provide up to 85% overall efficiency, so it produces less noise and heat.

  • LLC Topology

    In addition to its Bronze rating, its LLC topology also allows it to be more efficient across a wide range of loads.

    Built with high-tolerance capacitors for long-lasting, reliable operation.

    Great Value Power Supply – Reliable and Quiet

    I purchased the Corsair CX650M for a mid-range PC build, and it has been an excellent choice. The semi-modular design made installation easy and kept cable management neat, while the overall build quality feels solid and trustworthy. It delivers stable power with no issues during gaming or heavy workloads, and I haven’t experienced any shutdowns or coil whine. The fan runs very quietly, even under load, and the 80 Plus Bronze efficiency offers a good balance between performance and energy savings. The cables are high quality and long enough for a clean setup in a standard ATX case. Overall, the CX650M is a reliable, well-priced power supply that I would gladly recommend to anyone looking for dependable performance.

    Great power supply

    Great power supply. Replaced my dead one, and should be good for my next computer if I ever close to upgrade. It's funny that I have never heard about the cybernetics rating system even though I am somewhat of a PC nerd.

    Corsair = great products

    my older pc along with the main large plug has another motherboard 4 pin plug I thought this unit was not compatible but talked to a PC builder and he showed me the power supply has an 8 pin plug that also works on the the 4 pin connection. The plastic housing has a specific shape so you can only put it on one way the correct way. If you have an older motherboard like me this info might help. The only thing this power supply was missing is a small plug for my optical drive but I guess a lot of computers do not have optical drives now days or maybe the plug style has changed.
