    Default Corsair CX questions

    1. Does the higher wattage model have same noise characteristics as the low ones?
    Cybenetics only has CX450 CWT/GW and CX550 CWT, and CWT is quiter than GW.

    2. Does the CWT/GW avalivality depends on region?
    I mean like specific country only retailing CWT or GW... or is it just random across all regions?

    The CX 750 has the best noise profile of the line going by Cybenetic's datatbase with the CX 850 being on par with the CX 450 made by Great Wall (which is quieter in their database than the CWT models.)

    As for the CWT vs Great Wall availability, it's mostly "random" in that all regions are getting units from both manufacturers. The dual sourcing was done to keep up with demand, so which design goes where is completely dependent on when they were made and which factory had those pallets filled up. I think Jon did post awhile back about identifying which OEM you have based on serial number but I could be wrong.

    In a real world application, I wouldn't worry too much about which unit you got. If you actually look at the noise graphs from each design you'll see that up to ~80% load you're getting very similar noise profiles from each unit. If you are worried about that noise, then I would suggest just upping the capacity of the unit you buy.

    Based on the RPS number.

    It was a sticky. But I unstuck it because Seasonic got jealous.

    They probably wouldn't be jealous if you went back to the glory days of the CX400. It's all been downhill since!

    [Please note this is all sarcasm.]

    Is there normal CX(not CXM) on the database? For the original question what I meant was 'Is higher wattage CWT model also quieter than GW?'.

    As far as I'm aware, and Jon could correct me here, the CX 750 / CX 750M and up are not dual sourced. The CX 750 is Great Wall and the CX 750M is CWT. The CWT model is the one I was referencing before.
