PSU for SEGA JVS cab

[nonosto]

Hello

I use a 6-Way Single-Board JAMMA Switcher and 2 meters JVS cable for my arcade set like this:

So I have lot of power loose due the circuit lenght. I try with 2 SEGA PSU model:

For example 4.60V for my multi cps2 in fourth position.

Do you know a powerful PSU with 5V pots please?

NB: I tried with external PSU but the no common ground does lot of trouble.

Voltage drop happens in cables, relays, and connectors. Cranking up the 5V rail to compensate isn't ideal, because if you tweak it for the CPS-2 and then switch to a PCB that doesn't need much juice, like the MVS, the voltage could go over 5.4V.
