    Default Corsair CX450 PSU Review: Two Flavors, Tested and Compared @ Tomshardware

    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.

    Not sure I consider fixed cables a weakness

    As someone who builds a lot of PCs for other people; two major things I appreciate are a good case box and modular cables on the PSU. The case's box can be used to store everything that came with the build while a modular PSU can help make the simple act of wire management a breeze. Not even specifically only using half the cables that came with the PSU, but just for the fact that you can add them in as needed so you don't have an excessive bundle hanging outside of the case while you're working.

    Fair enough, as I have never owned or used a modular power supply; I defer to your experience.

    For me it is one less connector to fail; I seem to recall a thread here where the connectors on the power supply were melting.

    If I'm not mistaken, wasn't the CX meant to use a rifle bearing fan? The fan difference alone is, IMO, enough to make me wary about which version you get... An 8.6 DB(a) difference is also somewhat concerning... Sure, the GW variant has its upsides, but the lower quality fan alone makes it a questionable purchase.
    Just some nerd from 'Straya

    Aris is wrong.

    BOTH of these fans are rifle bearing fans. GW and CWT.

    Since I don't want to destroy those units, because I might need to retest them, can you please dismantle both fans and check on their bearings, posting some photos as well?

    Or you can ship to me their fans and I will do it. I just don't want to destroy my samples.

    According to the official specs of the respective manufacturers, one is sleeve and the second is FDB. If the makers of the fans are wrong about the specs of their product, then I am wrong yes.

    Fan factories have a tendency of using the same product code for several models. I never really understood why. Ok, they might save some money for safety certification. Still, it makes everything much more complicated for the customers.

    Unfortunately neither Hong Hua nor Yate Loon have a product number for rifle bearings. Which is where the confusion comes in.

    Neither of them are FDB. Neither of them are sleeve.

    They're both rifle bearing always have been.

    Yate Loon does not have a separate part number for using a rifle bearing. The sleeve and rifle bearing is interchangeable.

    HA1225M12F-Z, likewise, is not an FDB. It's a rifle bearing. They're both rifle bearing fans.
