Starting the cabinet all at once. It works! And here's how...

My plans to have my ATX power supply come on at all times have been thwarted by the limitations of the motherboard I choose to use.  

Pretty much, the idea was to short pin 14 on the ATX connector to ground, powering the motherboard.

It worked - in part - and only for a second.  I've done some research, and aparently the board doesn't like the timing coming from the PWR_GOOD part of the PS.

So, now I have another nifty idea:  a relay, that triggers a momentary connection, turning the board on.

Likely the power would come from 110V, and *just* activate the connection.  Just brige the gap in the pins.

I, knowing nothing of relays, don't know what to look for.  So I'm asking you saavy people for help.

If I understand correctly, what you're trying to do is rig up a button to turn on your computer.

This shouldn't be a problem and you shouldn't need to hook up a relay. Just connect a momentary contact switch to the spot on your motherboard that the case switch would normally go to. You should have a spot to connect a power switch and a spot for reset.

I'm planning on mounting some arcade buttons high on the side of the cab and using those for the power and reset buttons. You could just go to radio shack and get some cheap momentary contact switches that would work fine.

If I didn't understand your problem, please post again and give a few more details.

My old company buys a little board to do just that... Initially they where going to do a relay, but it wasn't 100% safe (for some reason) so they developed a board that was a little more smart.

Anyway, I think they might be more then how much you want.  I think they have been selling them individual for $25 (which is 10 bucks off getting a smart power switch and then moving your button for your PC to the outside of the cabinet... and having that power your cabinet...

but if your interested, I can get real numbers for you.

You sure didn't.

I'm trying to get everything to power on at once.  I tried rigging a power supply to be 'on' all the time, but the motherboard didn't like the PS being wired that way.  It threw the PWR_GOOD timing all off, and wouldn't boot.

So a relay that simply just bridges the connection of the power pins is what I'm looking for.  When power is applied, it just momentarily bridges the contact between the pins - but doesn't stay on.

The motherboard does not supprt resume after power off, so that's not an option.  And I'm not mounting any additional buttons.

I was looking for the same thing when I put a PC in my car for mp3s(cuz who wants to go to the trunk to turn on the PC every time you get in the car).  I know a guy that I work with who's super smart with stuff like that and we found a web page that said how to do it, if this isn't answered by monday, I can get you the answer then.  

Unfortunatly I ended up just running some phone cable to a momentary contact switch on my middle console in my car and I have to push the button after the car is started.  :(
