My best friend is an electrical engineer, so I emailed him a link to this thread.  His response:


--- Quote ---I've done this before, I think.  You just put a capactitor in place of the power switch.  A largish cap, say 100uF would work great, but make sure the voltage rating is at least 16v.  This makes it so that when you turn the AC power is applied to the PS, the machine automatically turns on.  
Is this what you wanted?

Can someone give this a shot?  I don't have any caps laying around.
SirPeale:
I asked exactly how it worked, here was his response:


--- Quote ---I've tried it.  It works as I have desribed.  Don't forget that a capacitor starts as a short and eventually becomes an open when it is charged.  This will simulate a short pressing of the switch.  Try looking for the cap in an old power supply, you want one of the large-ish (finger diameter) electrolytics.

If I am not mistaken that setup would be the same as holding in the power button on the pc and releasing it once power is supplied to the power supply.  I have tried this on my pc and it doesn't work.  In essence it's the same as using a relay as had been described earlier in the thread.  What we need is a way to close the circuit momentarily.  Something that would create a short one-time pulse when power is first supplied to it.
Then again I could be wrong.  Let me know if you get it to work Peale.
whammoed:
Heres a little different idea but it is unfortunately motherboard dependent:
Some motherboards have a feature in the bios that allows it to automatically boot after power failure.
That is how I set up my cab.  I have a main power switch for everything in the cab (much like an original arcade machine)  when I flip the switch the computer boots automatically.
