    Elektor had an article about using a PC PSU as a general PSU about 2 years ago.
    Suggest there should be a webpage on similar activities somewhere on the web.

    Just to be aware that a computer PSU can put out a lot of low frequency RF

    also it's 12.1V so you won't be able to charge 12V lead acid batteries with it

    that link was just a little scary.
    most computer psu's I've opened have had sod all space to add the banana plug sockets without them rubbing against an internal wire

    I found another link just like the link already shown but
    with 5 banana sockets on the side but the inside had a
    little bit more room inside.

    It's sort of a good idea on recycling the PSU from an old
    PC especially if you're after a lots of Amps at 5Volts but
    in amateur radio, that's not going to be too many people.

    thanks folks, I DID have several websites showing the process, I should clarify my question...

    anyone actually USE one in a radio setting?

    Some sites say there is RF interference......

    anyone have problems?

    RF interference does occur from some computer PSUs. I have a few ATX modified power units and no interference at all in my shack from them. In the past I have had interference to HF reception from Computers PSU but changed unit and all good then. I was lucky to work in a place where I could exchange a psu and try it in my shack, otherwise it is a hit and miss exercise.

    With a small modification you could probably get one of them to transmit directly on 136 KHz LF band.

    If you are operating in UHF probably won't be as big a worry.
