I noticed that 60n1 boards can use a pc power supply. All the power supplies. I've seen don't have a power switch. Is there some special kind or do people hack in a power switch on these things?
 
They usually have a switch right near the a/c plug; unless I do not understand you correctly.

The ones I've seen don't even have the switch on the back anymore. Ill check more thoroughly at the store again.
 
Yes, some dont' have a switch, you're right. There's a wire that you tie into one of the ground wires to make it turn on when the power comes on... basically when a modern computer comes on, there's a low voltage signal that comes from the motherboard to tell the power supply to turn the other voltages on, if you tie that wire that's looking for it to ground, the power supply will always be on as long as it's getting power (like a jamma switcher does)
 
If it actually has the same 20(+4) pin connector as a normal PC power supply, they probably already bridged PS-ON for you and you can just plug it in, no switch required. If you have to hack up the wiring though... find an ATX pinout, short PS-ON to ground. You'll need to regardless of whether there's a switch on the back of the PSU.

Yeah this is what I think I need to do. I found another one that has a switch on the back but the switch does not turn on the powersupply. The wiring harness I have is a Jamma one so it does not have the connector like you mention.

It looks like I either need to do a hackwiring job or find an old 286 power supply (like back in the good old days) where the switch actually does something.
 
Any modern ATX supply can be forced ON by jumpering the PS_ON line (green wire) to ground (black wire). This is easily accomplished with a paper clip or suitable bit of wire and some tape.

You can use any power supply to power the 60-in-1.

So following that logic, if I want a power switch to turn the game on, all i need to do is wire a switch in the middle of that jumper wire you are talking about? That should give me a On/Off switch for the machine then, right?

Except for the VGA monitor, of course.

I would not have the main switch on the jumper since that only powers the board (and maybe coin lights), switch the power before the Monitor and Marquee and power supply, etc.

I have powered most things from the computer power supply ( to jumper it on I think its the green wire to a black ground, a quick google search will find images with what pin #'s) but the computer power supply puts out both 12v and 5v so you can use it to power the coin lights and also marquee as long as you use bulbs with a higher voltage (they will be just a little dimmer) I've used 14v and 7v bulbs with no problems.
 
Yeah, just snip the green and black wire from the connector and solder them together (on the PS side). Then connect the power cord to the internal power of the cab (that is connected to the cab's power switch). Now, just turn the cab's power switch on, and the ATX power supply comes on to power the game board...

Actually I was thinking of using this in a bare cab. I was going to wire a power switch to the atx power supply, then plug the monitor and the marquee light and the vga monitor to a power strip and use the power strip to turn the whole shootin' match on in one shot.
 
If you're going to use a crappy computer monitor or LCD (which is almost as bad), then by all means. If you use a newer type CGA monitor, then that'll work. If you use an older CGA monitor, then you'll need an isolation transformer.

Still, no big deal putting a power strip inside, but I'd still make it a bit more "professional" and wire it to the cab's normal power switch. Make it look as "arcade" as possible from the outside and it will look great...
