    Default CX450M Initial impressions

    Got my CX450M today.
    So lets compare it to my ax1500i.

    40 dollar unit compared to a 400 dollar unit

    Maybe i'll do a teardown. But then I loose my warranty

    It's a budget unit, so who am i to complain
    0.5 Did Corsair get that primary cap custom made? Can't find it anywhere. It's a Nippon Chemi Con KMR 400V 180uf cap.
    1. Holdup time is probably not gonna meet the 16ms requirement. It's using a Chemi Con 400v 180uf cap for it's primary. It's TINY. Maybe i'll replace it.
    2. Kinda light feeling.... Or maybe i'm spoiled by my ax1500i...
    3. The chassis is sheet metal. But the sheet metal is definitely thinner. You could bend it by the fan intake...
    4. CWT smell. It didn't smell as bad as one of my friends RMx.
    5. Extremely worth it for 40 bucks. I don't think anything beats it. However, if you are used to Corsair RMx's and above, be shocked to see that the psu is wrapped in bubble wrap and the cables don't come in a fabric bag.

    Anyways, I'll post pics once im done studying

    But for 40 bucks, why bother getting one of those units that Turkey_scratch tore apart. Get one of these instead.

    Not sure if that primary cap is a custom order BTO, but that wouldn't be unusual. The one in the SF Series is. And your hold up time won't be 16ms. More like 10ms.

    The housing is actually not thinner. But the lack of deboss and emboss features and lack of "angled corners" does make it flex a bit more than an RM or up.

    In other words: It's not the metal itself that makes it feel more "flimsy". It's the simpler, folded design.

    Ahh. Thanks for clarifying it.

    PFC controller is the Champion CM6800TX http://www.championmicro.com.tw/data...ice/CM6800.pdf

    Supervisor IC is the Weltrend WT7502
    http://www.techpowerup.com/articles/...ges/WT7502.pdf

    Same as the Corsair RM750x

    Fan is a Hong Hua ha1225h12s-z

    Caps are a mixbag of Chemi con, Taicon and Samxon.
    It appears that there is a thermistor, obviously no relay.

    Rip my warranty.

    Anyways, if there is no review coming up, i'll probably take it apart more. I have to go study for exams

    Sorry about the potato images. My dslr is in for service. Also sorry if they scale wrongly

    Voltages measured with no load (so pointless basically) were:

    12.16v for 12v
    5.07v for 5v
    3.30v for 3.3v

    All measured using a fluke 87 multimeter. It's a keeper for my lab psu

    Please resize your pictures.

    Some of us don't have 4K monitors.

    Where are you seeing it for $40? On Amazon and Newegg it's $50.

    What about the controllers for the 5V and 3,3V buck converters?

    They're Anpec APW7159's. Why? Is there a problem with them?

    I don't think so, I just wanted to know if they're equipped with OCP.
    They are but the unit is still lacking in OCP for 12V, isn't it?

    The WT7502 has only got OVP and UVP (SCP) for 12V, 5V and 3.3V, no OCP.

    By the way, are those also the controllers for the converters in the RMx units?
