    Default Corsair CX450M review (Dutch)

    So there it is, the first review from the new CXM series. Imo the 450W version is also the most interesting version because it's more then enough for most game PCs with one graphics card.

    So about the CX450M it's based on a modified RM450 and uses double forward, with synchronous rectification and DC-DC for the 3,3V and 5V. The voltage regulation is great, ripple is OK, except the 12V under full load that's a bit mediocre.

    Quality is good for a PSU in this class, only the 12V caps aren't that great. With some better caps here and a bit lower ripple it would be a great power supply.

    New models should have a rifle bearing fan, don't know what I have. Rifle and sleeve have the same name and I don't want to destroy the fan.

    For the silence freaks it's not really an option with a minimal fan speed off 800 RPM which is a bit much.

    According to the specs on the Corsair site there isn't OCP or OTP, but there should be OCP for the 3,3V and 5V and the Anpec Electronics APW7159 also supports OTP, but Corsair says no.

    Anyhow it's still a good PSU and good buy of course.

    Review in Dutch: https://tweakers.net/productreview/1...ir-cx450m.html for people who can't read Dutch, use Google Translate.

    Dat -12V performance...

    Nice review, the unit is in line with what's expected at its price point.
    Not sure about those Samxon GirlFriend series caps... Somehow I feel the aggressive fan profile is mostly for their benefit. But I guess they will last the warranty period, plus maybe a year. CWT sure loves those.
    Careful what you wish for... You just might get it.

    Copy and paste error.

    The unit does have +3.3V and +5V OCP and the unit does have OTP.

    +12V relies on OPP.

    I love how PP9 can't even fit in range on v-reg charts.

    Yeah Corsair definitely nailed it.

    That indeed is unfortunate. Three better caps and it would look a lot better and maybe an extra cap for less ripple.

    Yeah that's also what I said in the review, that it probably would have OCP on the 3,3V and 5V and that OCP on the 12V is a bit useless because there is OPP. I also saw the OTP support in the Anpec Electronics APW7159, that's one is used for the OTP?

    Yeah that's gonna be a fun review.

    I keep seeing the word "diet" in Google's translation. The CX450M diet.



    Lol, it also calls power supplies "big bastards" at one instance

    Just finished the review. Good unit. Still very nice for $50. I just don't get the logic with that fan curve. Sits at 800RPM all the way up to 75% load. Seems a little strange to me, but I think Corsair just wants these to last 5 years. It also makes me question how these would last with a machine that is used often and is about 75% of the load. If the fan is being set at 800RPM at 25%-50% load, the load territory where most people's computers will be in, it just doesn't make sense that it wouldn't be set lower. If they have faith in it to last 5 years under a heavier 50-75% load, why run the fan at the same RPM under a lighter 25-50% load?

    It's as if they intentionally, for humor purposes, turn Dutch translations into food-related things.
