    At to atx makes of a happy carputer

    i can get on of these: ACE-865V for 20 BUT its an AT supply

    the thing i like about it is that it takes 8-16VDC input oh and its cheap

    http://www.arisecomputer.com/ps/ace800.asp

    is there any easy way to convert at to atx? i could probably do it with some faily simple voltage regulators.
    you get a +/-12v and a +/-5v



    i guess all i would have to do is have a zener op amp and tranny based voltage reg running off the 5v line. should be fairly easy
    what kinda current does the 3.3v line have to suply?

    im asuming that if i just turn on all the voltage lines the mobo will power up...it doesnt have to be "expecting" it to happen? does anyone know if edens/epias need a power good signal?

    I just accidently bought one that I am now attempting to not buy for this very reason :-)

    I'm a bit of a fool when it comes to this stuff, but isn't that a function of an ATX power supply? All that soldering and stuff is too hard for me - the Eden board has an ATX connector, so I'm looking at ordering a PC Power & Cooling PS (see my thread asking questions about this ps for a url.

    Current pricing is $110 USD.

    If you connect the appropriate atx plug to it you may be in luck, not all ATX boards use 3.3v. It does depend on its age. Mine is ATX with a Cyrix 333 cpu and I only use +5v and +12v, no -5v or -12v or 3.3v.

    ill be putitng it in a eden
    i recon they would use hte 3.3v
    but as i say im fairly confident i can make it.

    i guessss im not sure about how to turn in on. the sproggy just goes doesnt it....it doesnt leave a 5vsb or need the mobo to have its power button pressed...does it?

    Have a look at Mastero's web site - I'm sure he used to sell AT PSU > ATX Motherboard converters.

    think they were $10...

    Interesting, I believe this is the cheapest and easiest solution so far for a simple ATX system, am I correct? Can you please let me know how you make out with it and what the total cost was, i was gonna order the caseoutlet power supply mentioned in another thread (atx <90.00) but thats out of stock again. thx

    I could be (and probably am) mistaken, but i think thats just a pin adapter (ie turns a at connector into a atx connector), and doesnt add or change any of the voltages.

    you could be mistaken
    you might not be though
    im gonna email him later to see

    if it does moneky with the voltages...as i hope it does...but it might not...then it is the cheapest way of doing it. and proably easiest

    ill prbalby end up paying 30 for the psu (it dont inlcude VAT or shipping on the website). although it will ost about 10 more if i need to make the propper atx adapter (overpesimistic estimate...just to be sure) with the voltages changed and some emulation of a propper atx on and offness

    Hey guys the converter is just a pin converter ..!!

    But there can be a simple solution for this to make it work like an atx ..

    What we need to make this Psu to ATX is

    3.3vdc

    pin14 (for soft start)

    5vdc Standby

    Power good

    hmmm let see what i can come up with give a week ....

    thanx
