Naomi set up question with a Capcom I/O

[guinness1701]

Evening,

I am getting a new setup together. I plan on using a PC ATX power supply to power a Naomi 1, Net DImm, and Capcom I?O. If I use the atx harness to power both ports on the Naomi. Do I have to still power the capcom I/O through the jamma cable?

Originally the Capcom IO passed power from JAMMA to the NAOMI. If you power the NAOMI directly as is advised for your target setup, then yes, JAMMA power must be present for the CAPCOM IO itself. Leave the power output from it alone/unused.
