Hello all,
Up until recently I had an old PC running Windows in my cab off an ATX PSU. The hard drive broke about a year ago and I've just got round to sorting it. I've replaced the faulty monitor and the PC with an LCD and a Pi4 and got shut of the ATX PSU. So far so good.
I have an issue with the arcade PSU also currently in the cab, at the moment it powers the coin mech and the marquee light and here is my issue; It won't ever be used as a jamma cab again or with a CRT so should I get rid of the PSU and the transformer and replace it with a more simple power setup for the coin mech or, as it's still working, can I use this PSU to run some LEDs for the marquee and an amp for the speakers?
There doesn't seem to be any rhyme or reason to the colour of the cabling from the cab PSU and there's a good few snipped ends on the whole thing so I'd rather not go poking around and zap myself. I'd be happy to muck about with an ATX PSU as I'm used to that but the cab PSU is another story.
Is it possible to just run the 12v required for the amp and the 5v for the lights directly off the terminals on the cab PSU?
Sorry if this is an obvious question!

No sense in abandoning something that works if it puts out the voltages you need.
I'm not really familiar with jamma but isn't the wiring coloring standardized?
If you post a picture and have a tester I bet it can be sorted out with a bit of help.

Check out part 3 of my for dummies series on YouTube. I get into simplifying the wiring connections using a DC to DC converter

It is easily possible to run coin door and amp from ATX PSU. Just make sure it is a decent PSU with enough power "headroom" to do all that as well as PC and anything else.
There is also no harm in leaving the arcade DC power supply in there. May as well as it has all the connectors and everything all setup and just there. Just make sure you don't get the grounds mixed up between power supplies.
