    Default Question on Seasonic CORE series

    Good afternoon (or whatever time zone you're in) folks.

    Long time user and reader of the website, first time poster. Thank you all very much for your information it has been absolutely priceless over the years.

    During this current global pandemic the stock levels of power supplies has dried up and prices are well out of whack, at least here in the UK, so finding a relatively priced power supply of reasonable quality is becoming very difficult.

    Which brings me to the Seasonic CORE range (the latest one).

    The prices (around 70-80) seem reasonable, but I see from the Seasonic representative above that these units use a sleeve bearing fan, which is greatly disappointing.

    Are these units still of reasonable quality for heavy usage gaming systems or should I advise people to wait for other units to return in price and stock level?

    Many thanks.

    For my standars, i will stay beware from every PSU that have a sleeve bearing fan. Also beacause for a heavy usage, a reliable PSU with a reliable fan is mandatory!

    Indeed, that's my worry.

    I worry about that, too. I will not use a sleeve bearing fan with a heatsink, for example. Yet we have a Yate Loon case fan that has gone for years. I have never had to swap it out for any of the 4 replacements I stocked up for it.

    You could PM the Seasonic rep and ask him (or her) why ss used a sleeve bearing fan with that PSU.

    The reason is quite simple, cost reduction.

    You are, right, of course. But I would ask, why did they choose THAT fan?

    Cost from sleeve to rifle is minimal. I'd love to see whole list of the cost downs in that PSU.

    EDIT: Is there are review or internals of it somewhere? I don't even see it on Cybenetics.

    Are modern (synthetic) lubricants helping with the life of sleeve bearings?


    https://www.nmbtc.com/white-papers/b...g-performance/

    "
    ...sleeve bearing fans can maintain life spans comparable to their ball bearing counterparts when the sleeve bearing fans are mounted in vertical positions.
    "

    Modern power supplies have their fans mounted horizontally, but old supplies had the fan vertical.

    Thank you very much for these.

    Given my relative lack of knowledge and relying on Google translate, these units sound actually okay to me, even with the sleeve bearing fan (covered by warranty for 7 years).

    Am I reading that right, and if I am not, could anybody explain what it is that SHOULD be better about these units? (outside from the obvious fan discrepancy)

    Thank you all for any and all input, it is very much appreciated.
