Sega Model 2 JAMMA power Question

Post by Glossectomy »

So I recently picked up Virtua Fighter 2 pcb. I verified that everything was working. I wired up a Model 2 to JAMMA loom and here's where I'm having issues. My power supply is 5v/15a. After powering everything up I'm only getting 4.6/4.7 at the JAMMA edge with the PSU as high as it goes. I get a screen saying that I need to turn up the power to 5v when I turn everything on.

I'm trying to figure out what options I have to get this working. I considered running 2 of the 5v/ground lines from a second power supply. But if there's another option I would be willing to listen to suggestions. I picked this up for $20, and mostly because there are other Model 2 games I would like to get.

Thanks in advance

Model 2 are power hungry, sounds like you need a stronger PSU.
I have to adjust my PSU to 5.2V for Zero gunner to run reliably without crashing.
Mine has 15A on the 5V rail. The wires I'm using are not that thick so I think you just need a stronger PSU.
