Corsair teamed up with CWT once more, and the result is good. The modern exterior design and the updated platform will allow the CX750M to retain its position in the market and compete with the other budget 750W PSUs. There are several good choices in this category, including the XPG Pylon 750, the Thermaltake Smart BM2 750, and the Cooler Master MWE Bronze 750, but the major competitor for all these units look is the EVGA SuperNOVA 750 GA, which, although it belongs to a higher category, has the same price tag. 

The 750 GA offers higher efficiency, has a fully modular cable design, and is supported by a ten-year warranty, so having it at the same price, 80 dollars, as the CX750M creates enormous problems for the latter. To remain competitive, the CX750M and the other 750 Bronze and Silver units must have at least 20 dollars difference from the 750 GA. At the same price, it just doesn't make sense to go for a lower efficiency and performance unit.

The Corsair CX750M has good build quality and decent overall performance and won't be noisy under normal operating conditions. It is also supported by a long warranty, which the rifle bearing fan and the capacitors that Corsair used will outlive. Its main problem looks to be the relatively high price tag, although this can be countered with a Corsair discount code if you're lucky. It currently goes for 80 dollars on Newegg, and for this amount, someone can get the more capable EVGA 750 GA, so Corsair should do something about the price and lower it as close as possible to 60 dollars.

    Another great review!

    Why do you prefer a full modular cable set up to this semi-modular ? At this price point I think semi-modular is "best". One less failure point and greater efficiency. I don't think custom cabling is a consideration for this range. I think Semi-modular should be considered best practice outside of Vanity/RGB/Bling focused lines.

    For appearance sake I do think the exit point of a semi-modular "main cable" of could be made to visually match the other cables without giving up the advantages.
