We would like to thank Corsair for supplying the review sample.
Corsair’s CX series is very successful amongst budget-oriented users that want a PSU that is both affordable and highly reliable, and from a company that offers great support when needed. Following the increased demands of today’s users, Corsair wisely decided to enrich their CX line with units that have modular cables. This feature is probably the most desired one amongst buyers, but it is also the first one to be cut in budget PSUs because of its significant cost.
Every one of the existing non-modular CX units now has a modular counterpart, which adds up to a total of four new CX M members with capacities ranging from 430 W to 750 W to completely cover the entry-level and mid-capacity categories. Their modular cabling system is the only new specification. Everything else—the efficiency certification (80 Plus Bronze), a single +12V rail, and the warranty period—remains the same, at least on paper.
In this review, we will take a good look at the second strongest CX modular unit, the CX600M. It houses enough PCIe connectors to power a mid-range system with one high-end VGA or two smaller VGAs with a single PCIe socket each. Such a PSU would normally have four PCIe connectors, since its capacity can easily support them, but Corsair decided that two would—for unknown reasons—be enough. We don’t agree with this decision because it dramatically restricts the usability of the unit and expect Corsair to offer an upgraded version with more PCIe connectors soon. Users will have to cope with having only two of them until then. But enough has been said. Let's move on to the main portion of the CX600M review.
