    [subject changed] sproggy wont boot my Mobo pse help

    hi,
    today after getting a fine heatsink - my sproggy 2.8+ is now 100% finished but not working
    all output voltages except 5VStb ( purple wire ) are 0V

    All is connected after the shematic i got from maestro
    I think its coming from the relais :
    the relais is not clicking , and I have no ground on on of the pins so that might be the problem -

    here are some pics of mine perhaps you find a mistake
    I build it after this shematic :

    My sproggy in unfinished stadium:


    here are some pics of the sproggy
    big images to see better

    ok buddy let me see .. do these check before i answer you ques..

    a) connect both main and remote to positive and ground to ground

    b) check if your getting the 5vstby from the 78L05

    c) connect ground to pin 14 and see if the relay click (if it does then check the volts on the PSu ..

    Let me know ..

    hi maestro

    a) done
    b) done I got 4.5V ,
    when PSU is on I get
    12V is 12,22V
    3.3V is 3.3V
    5V is 5.05V
    and 5V on grey wire
    all neg Voltages are also correct

    some one on Divx-car told me to try the following
    put a big C ~1000uF between GND and 5V .
    ( i made a picture to show better)



    c) works relais clicks and psu is on

    when PSU is off ( relais not clicked) i get 4.42V between green wire and GND. 4.63 V between purple and GND.

    could this low "5V" from the 78l05 be the cause ?

    thanks

    ok till now everything is fine ....

    Your sproggy is working perfectly fine... dont put the big caps... !

    now check the following...

    a) The pins on the ATX power connector is wired correctly... double check it ....

    b) Check the power good delay .... if its giving proper dealy use a multi meter....

    Let me know..

    ok for the cap - the guy told me that on his sproggy that worked so i tried

    I toked a ATX connector from a broken PSU of a friend of mine - not the cables /connectors which where in your semi kit i bought.
    so i think all is correct.

    for the delay what should it be ? how to measure it ?

    thanks

    use two multimeter and check the +12 and after how long the power good kicks in ..

    If possible change the chip 4049..

    a bit hard to mesure - but 5V kicks in ~1sec later than 12V

    BTW are the ~4.6V for 5 V stndby ok ?
