Thread: IBM XT PSU - replacement.

  1. #1

    Default IBM XT PSU - replacement.

    Hello.

    I have two chances to buy XT PSU for future replacement.
    First is working similar to one that sit in my XT, but have less stickers, it's a clone?

    Second is made by IBM, it's very different than one from my XT, untested, seller say, that it's about 150W:

    Regarding the first PSU. The big yellow sticker is good, but IBM made XT PSU's had other stickers (as you commented), mainly the one showing the IBM part number. See attached photos. With nothing to identify the PSU, how will you know what wattage it is rated for?

    Regarding the second PSU. Poor pictures. Do an Internet search using the IBM part number. That should let you know what the PSU belongs to.

    That second power supply looks like the PC/AT supply.
    If it is a PC/AT power supply ,then it will not fit in the PC/XT
    case.

    I'd like to get second PSU, made by IBM.

    Seller said, that's untested, so I asked him to connect something to the PSU and check if it will work.
    He connected CD-ROM, as he haven't anything enough old to try it with the PSU, fan started to work, he heard ticking from CD-ROM and after a while fan shut down.
    When he connected two CD-ROMs, fan was working a bit longer.

    CD-ROM draw about 20W of power, so it should be enough... or maybe it needs more? Or mainboard should be connected?
    I'll ask him to check if he could reject CD-ROM.

    You should get the dimensions of the PSU case from the seller and see if it
    matches with your PC/XT PSU case. From the pictures you posted, that
    looks like a PC/AT PSU. Which is quite a bit larger than the PC/XT PSU.

    Okay, I asked seller for dimensions.

    I saw similar PSU on XT review page at Uncreative Labs.

    And hmm... this is clone too, eh?

    ...that would explain, why it's working so loud.

    That one looks like an AT as well.

    He said, that it's
    29 x 12,5 x 14,5 [cm]

    That look like bigger PSU than standart XT one.

    So... buy that clone one for 12$?... yes, price is strange.

    Does the XT power supply have a fan in it. Would it spin up even if the power supply was unconnected to anything?
