Corsair's CX450 is built by two OEMs: CWT and Great Wall. Is one better than the other? We tested both to find out.

Corsair's budget-oriented CX450 is unique in that it's manufactured by two different OEMs--Great Wall and Channel Well Technology (CWT)--each of which uses a distinct platform. The only way to tell them apart is by their RPS numbers, reference designators given to each model. Both configurations share the CX450's principal weakness: fixed cables. However, they both utilize modern platforms featuring LLC resonant converters and voltage regulation modules, along with high-quality fans.
