I think I know the answer already but would like to know is it possible to bypass the original XBOX 360's PSU and power the console directly from the JAMMA edge connector.
From a quick look the 360 requires a 12v, 5v and a Ground input. So the JAMMA PSU supplies the correct voltages.
But am I right thinking as the JAMMA PSU only outputs ~2.5A on the 12v and as the 360 brick supplies 14.2A that the JAMMA PSU isn't supplying anywhere near enough current to do the job?
