PSU compatability

    I need to replace a failing 350W PSU. My MB is a Chaintech 7AJA Socket A
    with 1Ghz Athlon. What do I need to look out for in PSU specs to ensure
    compatability (other than 20-Pin plug ) ?

    To be safe, make sure that the current ratings on 3.3V, 5V and 12V are
    the same or above the old PSU. You may also need to have -5V, which many
    modern PSUs do not supply any longer. Check the mainboard manual
    for that.

    And make sure that there are enough output cables and sockets of the
    right type for whatever you have installed (not just the motherboard,
    but disks etc.). Or that you are prepared to fit adaptors and/or

    You may also need to have -5V, which many
    This certainly seems to be the case: After much searching, I finally settled
    upon a Jeantech 350W PSU, because it was one of the few I found that did
    support -5V. Alas, they appear to have updated the model; the one in the
    shop did not have a -5V output. Back to google.
