    Post circuit diagram of PS

    does anyone have a circuit diagram of the primary side of a standard, switchmode computer power supply?? or know where one is?? I need it!!! well, not really, but it would be a great help...

    Get the book: The art of electronics
    www.bn.com www.amazon.com

    Not only will that show you what a computer power supply looks like, but it will help you by not having to ask us questions like, "What is a diode?"

    WELL EXCUSE ME!!! but I take that as an insult, I know what I am talking about, I believe that I would know equally as much as you, and I don't like being put down... I only wanted the scematic in an effort to use the primary side, with a re-wound transformer to get +-28volts DC to experiment using switching power supplies to power high power audio amps.. I have power lower power amps with a standard computer power supply, and haven't noticed any audiable switching noise when used with higher power amps.. I am trying to construct a 50watt per channel amp that will fit into a case with footprint the size of 1/4 a piece of A4 paper... Now, any bets that I won't manage this task?????

    Excellent book, I give it two thumbs up! Haha, seriously though, this book has the best collection of practical information I have found so far.

    Hey no worries mate, we all had to start somewhere! I don't think he meant to put you down.

    Check out this web page:
    ATX schematic

    It uses no optos, and a gate driver transformer. I think it would be pretty easy to hook my supply to this type of circuit, although I've never tried. I've never seen one like this in real life though. This seems like the one you might have.

    Sheesh dude, relax. Take some Zantac 75.

    You can't say that you havn't asked some questions that would have been eaiser answered from reading a book for 20 minutes.
    Your the one with 789 posts in 5 months. This one comes to mind http://www.mp3car.com/cgi-bin/ultima...c&f=9&t=000104

    If you don't like my advice ignore it. I would have never made it to where I am today with out the constructive and destructive critisism I got from my peers. Sorry if I insulted you.

    Yeah, well, I stil didn't get a working circuit from that topic.... I ended up finding the sproggy design myself, and using the power good from that...

    Sorry for snapping at you.. friends??? he he??
