    Default corsair rm650x vs rm650i

    i read that the differences between the two are :
    corsair link in the i version, X has rifle bearing fan, i has fluid bearing fan and the i have multi rail.
    the main thing that worth to me for buying the 650i is the different fan bearing, which some say that it'll work more quietly and may last longer.
    is it so?
    then i read this:
    "The only problem with this type of bearing, besides increased production cost, is that during the start-up phase and until the lubricant is pumped all the way up to the bearing's top, there might be increased friction, meaning that these fans aren't suitable for applications involving lots of starts and stops (in PSUs featuring a semi-passive mode)."

    https://www.tomshardware.com/reviews...1,4193-18.html

    can someone help me to make my decision which of the two to buy?
    i don't care to pay a bit more for the i as long that i get a more quiet operation

    Rifle bearings are fine.

    And "multi rail" is not the only thing that makes the "i" and "i". You can monitor voltages, fan speed, temperature, etc.

    thank you.
    i know all that.
    as i said , the main subject that important to me is will the fluid fan bearing in the i version run quieter compare to the Rifle, as it was said in some places?

    I don't believe the FDB is any quieter. I've heard them both at very low RPMs and neither make any bearing noise. You'll hear electrical noise more than anything else. The advantage of the FDB is longevity; though the rifle bearing will still probably last well past the 10 year warranty period.

    the strange thing is if Relying on CYBENETICS LAB, the rm650x is even quieter then the 650i.
    https://www.cybenetics.com/index.php...fID=28&volts=1
    so since i'm a user that don't "play" much with my pc parameters i guess that there is no point to me to pay more for the i version.

    there is also a rm650x v2 version.
    i read that it's a bit smaller ,but a bit more deficient and quiet then the regular rm650x.
    is it worth buying the last one instead?

    The new RM650x is the same size as the old one.

    Only the RM750x and RM850x are smaller.

    The 2018 model uses a wireless design internally. It's similar, though not quite the same, as the Bitfenix Whisper M (though the Whisper M has multi-rail OCP and an HDB fan compared to the RMx's Rifle bearing)
    Just some nerd from 'Straya

    The HDB fan IS a rifle bearing.

    Lul I'll never agree to call it wireless when it still has 4 wires coming from the AC socket and OFF rocker, a separate grounding wire going from AC socket to PSU case, and one more thicc GND wire going from +12V FET board to the corner of main PCB. Sorry not sorry IMO the only wires acceptable to be called wireless are the fan cable and transformer taps (and even the latter could be done away with!)

    Yes I know the main point is that the modular board is connected by bus bars and no cables, but let's not call the entire PSU wireless.
