What PSU do I need for Cade Project.

Hi everyone,

I have a Tekken Tag Tournament Cabinet that I'd like to get up and running now that I have a little more free time. Heres my issue.

The monitor went on it some time ago, so I gutted most of the old electronics like the PSU and Monitor etc. The controls + original wire harness and the TTT Jamma board are all that remains. I have a PC ready to be up into the machine as well as a Jamma changer. So my question is I know i'd power a monitor and PC with but how am I powering the TTT Jamma board or the Jamma changer? What would I need to get that running?
