PC Power Supply startup

[wahumpe]

OK -please forgive if this is posted wrong or a repeat - first post from a newbie here. I searched but couldn't find info on this...
Was planning to use a PC power supply for a 60 in 1 na dremoved it from an old PC. Question is, now that it's removed how do I turn it on once it's plugged in? Do i need to connect a switch to a set of wires and if so, which ones? Thanks in advance, have already learned a lot by trolling previous posts...

Short green wire to black wire or you can insert a switch between them but its not really necessary if your supply has a switch on it already.

Thaniks. Looking at the power supply I don't have a single green wire coming off of it. There are two wire bundles - one with two black, an orange and a yellow that leads to two four-hole molex adapters (p4 and p5) and another smaller four hole connection (p3). The second larger bundle that leads to another 4 hole Molex (p6) and a 20 hole (p1) and 12 hole (p2). Again, no green wires, grrrrr. Thanks again.

OK Here is a pic.  On your 20 pin connector you want to connect ps_on to a com.

OK. Not to be too dense but the one indicated by green should be hooked up to what exactly?

Am I correct that the 4 hole Molex would connect directly to the 60 in 1 board? I have the PCB connected to an LCD screen and a Jamma harness to run to the control panel, sound and marquee lights. If I hook the board to the PC power supply this way all I need to do is get it switch on right??? Is there anything else that needs to be hooked up?

Again, sorry to be so simple, any help is appreciated...

PS On is connected to a COM or Common (One of the black wires).  The 4 pin molex plugs into the PCB. Make sure the dip switch on the board is switched to select VGA output.  You will have to put in a coin before the menu will allow you to select a game or put it on free play.  You also need to have a test switch working to go to the software dip setup.

That should do it. Thanks a ton!

So, still no luck. I did learn that pinout from my power source is a bit different as it is an older Dell that did things a little differently for some reason 
Here's the pinout of the unit I have: http://pinouts.ru/Power/dell_atxpower_pinout.shtml I ran the orange to a black ground and still got nothing...

Oh god...those old Dell power supplies.  "Let's change the pinout so much that it could BLOW THINGS UP if you hook it up to a standard motherboard, but we'll keep the connector the same, and the new pinout isn't any better than the standard one".  Idiots.  At least they don't do that, anymore.

If you don't have much hooked up to the supply, be aware that PC supplies require a minimal load to start up.  I usually just hook up a hard drive.  A really tiny load like a few LEDs is often not enough for them to safely run, so they just shut down.

Also, you want the gray PS_ON line, not the orange power good line.
