    Question Corsair CX600M - buy replacement fan or just buy a new PSU?

    Not long ago the fan in my old Corsair CX600M started making an obnoxious noise that's been driving me crazy.
    Here's a video of the sound: https://www.youtube.com/watch?v=87C-YX1871s


    It uses a Yate Loon D12SM-12 fan which I tried swapping for a spare Noctua NF-P12 Redux, but unfortunately (and probably unsurprisingly), it didn't work.
    I've checked Mouser and Digi-Key but am having a hard time finding a similarly spec'd replacement.


    So the question is: is it worth the effort to disassemble the PSU yet again to replace the fan?
    And if so, are there any suggested fan models?


    If I go the route of buying a new PSU, I'm not sure what option to choose from. With many PSUs out of stock and a lot with crazy high prices, I've narrowed it down to a few options but am open to suggestions.

    -be quiet! Straight Power 11 (650W, 80+ Platinum)
    -Corsair RM750x (750W, 80+ Gold)
    -Phanteks AMP (550/650W, 80+ Gold)
    -Super Flower Leadex III (750W, 80+ Gold)


    The be quiet! Straight Power 11 650 Platinum is available for $135 on Amazon, but for the same price the RM750x has a 10 year warranty and an extra 100 watts. The Leadex III is $130 on Amazon, but I worry about warranty & support here in the US.
    I was also looking at the more reasonable 550/650 watt Phanteks AMP for ~$85-100 but it's sold out

    While 750 watts is clearly overkill for my system, the price difference is small enough that it (hopefully) won't hurt to have the extra wattage.


    Apologies for any formatting issues etc., this is my first post

    In what way did it not work?

    The noise didn't go away.

    But the best choice for your PC is the be quiet! Most suitable imo, high-end PSU with a high-end fan. The current PSU isn't something you should use in a modern PC. Old double forward design with group regulation.

    When I power on my PC the fan spins as normal but then it shuts off moments later
    And no the CX600M doesn't have a fanless mode to my knowledge lol

    The be quiet! does seem solid, but do the shorter warranty and lower wattage matter much?

    I never thought I'd feel bad for a power supply, but...

    I bought it almost exactly 5 years ago, is it really that old? I guess to be fair it never was high end



    Thank you all for the fast responses!
    (apologies for the double post, I couldn't figure out multi-quote)

    Exactly. It was a cheap PSU with cheap parts. Never meant to last more than 5 years.

    Looking at your PC specifications the 450W version is also more than enough. So the 650W certainly is.

    Personally I wouldn't care about the shorter warranty if I knew I had a really good power supply, because the chance of having a problem is really small.

    That's what I thought. If my $70 Corsair CX600M has lasted me this long, I'm sure the be quiet! will be plenty reliable.


    Seeing as Amazon only has 10 left, I went with the be quiet! Straight Power 11 650W. I've actually been looking at PSUs for around a week now and they kept selling out before I could get one!


    Yeah I can easily get away with a lower wattage unit. However, the price difference is so small & many of the cheaper ones aren't available, so it makes more sense to get the 650W unit.
    ($120 for 550W or $135 for the 650W is around 12% more money for 18% more wattage)
    And who knows what kind of power the next generation of Nvidia GPUs require (hopefully not as bad as Vega lol)

    The Yate Loon D12SM-12 is $7 on ebay

    You could fix the supply and then keep it as a spare
