Running other things off the PC power supply. Where do you draw the line?

Sounds as simple as wiring a DC socket to a yellow and black wire. If I figure correctly, I wouldn't need to buy a smart strip either if I have nothing else that would plug into an AC outlet.

I've been running a 12" touchscreen monitor off an old 250w AT power supply for a year or two and it's been fine.
(it's also running a megatouch board and IDE/compact flash drive)

I'm telling you, nothing says "authentic" like a real arcade power supply!  ;D

Like others have said they are pretty cheap on ebay or if you have some old PCs laying around you could pull the power supplies out of them.

Yeah, it's not about the money or the modding.  It's that I'd get a certain amount of satisfaction from the simplicity of running everything off a single supply. I was even looking at line filters (which would cost more than a power supply), but don't know enough about these things to be confident that the PC would be safe.

The actuator is only drawing around 1A with no weight on it, so I'll probably end up running it off a laptop block.
I'll most likely mount it to the bracket that I'm building the rotating mechanism onto.
That way, the rotating mechanism/monitor mount will be a self contained unit with just a power plug and signal plug to connect inside the cab.

I plan to sit down and carefully read your build thread before getting too far into this.  :cheers:

I hear you, I gave up on simplicity once DaOld Man talked me into automating all these things  ;D. I think I'm just being overly cautious by using so many. It is entirely possible on my cabinet to have the 3 actuators and both rotating motors all running at the same time. I probably don't need a separate power supply for the servos but I thought it was a good idea to isolate them from everything else. I have plenty of room in my cabinet, I might as well fill it up  :laugh:
