    Hi, I am new to this forum and have already found quite useful. Thanks :eek:
    So I have a friends emachine (T2792)that is completely dead; no lights, sound or fans. He said one day it just wouldn't power on. So I do the reasonable thing and go to the local puter shop and get a replacement P/S. I get it home open it up, and notice that she sold me a 24 pin ATX which is not what I need.. I am replacing the Bestec ATX 250 12E which has a 20 pin connector. Now I think that I know the answer : that one can not use a 24 pin PS on a 20 pin board, right?
    Well it just so happens that I have an older ATX P/S that does not have the P4 12v connector. Is it possible to use the 12v connector from the dead P/S on the older P/S? Where can I get the +12v needed?
    Any help would be greatly appreciated of course. NO doubt I may just have to fork out $50 to get a OEM replacement, but that will take too much time.... Thanks

    ~ Jeff

    most 24 pin power supplies have a removeable 4 pin connector at the end that allows it to be used on a 20 pin mobo. and if it doesn't, then you can just buy a cheap adapter like this one:

    Radio Shack may have them. Might save a wait.

    Or, you could just return the new PSU you bought and buy one that has a 20-pin ATX connector (most decent PSUs have an interchangeable 20/24 pin connector anyway).
    Those adapters can be a weak link - representing another two unnecessary joints in the power supply path.
