This is my Namco 2x6 power supply, there are many others like it, but this one is mine. After spending too much time dealing with power issues off the JAMMA connection I opted to use an ATX power supply for my Naomi hardware and then adapt it to the Namco systems. ~150 Watt using an 8AMP 12v power brick. Added an inline power switch since the ATX adapter has the power on pins shorted.
