Corsair's CX series consists of both non-modular and semi-modular units. It was recently upgraded with new members and improved versions of older ones. The CX650M is the third strongest member of the line, featuring 650W capacity and a 40°C rating. igh-end PSUs might offer top-notch performance, but the models that drive sales are much more affordable. Corsair's CX family is the company's mainstream line-up.
The CX portfolio includes modular and non-modular products; the former is distinguished by the CX-M brand. There are five CX-M units in total with capacities ranging from 450 W to 850 W, covering the most popular categories. All of them feature 80 PLUS Bronze efficiency and have a 40 °C temperature rating for continuous full-load delivery.
“The CS Modular Series is designed for basic and midrange PCs, but offers features and performance traditionally reserved for higher-end models. 80 Plus Gold efficiency and a thermally controlled fan ensure quiet operation and lower energy use, and the modular, detachable cable set makes installations and upgrades faster and better looking.”
‘’80 Plus Gold rated efficiency saves you money on your power bill and produces less heat than less efficient power supplies. The flat black modular cables allow you to enjoy fast, neat builds. And, like all Corsair power supplies, CS Series Modular is built with high-quality components and is guaranteed to deliver clean, stable, continuous power.’’

The CX650M is compatible with Intel's C6 and C7 sleep states, since it uses DC-DC converters for generating the minor rails. In addition, it is equipped with a full set of protection features, including over-temperature protection, which we consider a must-have. The CX650M's dimensions are compact, thanks to a reduced depth of only 14cm.
As mentioned, there is no semi-passive mode and Corsair claims compatibility with the latest ATX spec (v2.4). Finally, the provided warranty lasts five years. We're comfortable with that coverage. Interestingly, the CX650M's price on various online stores is way lower than the company's official MSRP. For its own reasons, Corsair lists an estimated price much higher than a Bronze-rated PSU should sell for. It's a good thing street pricing is more sane.
