Title: Power requirements for a Jamma test rig
Post by: Hurray Banana on January 20, 2006, 10:15:01 am

I'm going to build a jamma testing rig following the instructions on the cps2shock site.

I've got an old AT power supply rated at 90W, will this be enough for a jamma testing rig?

Likely.  It depends on the board, of course, but it should run okay.

What is the amperage rating on it?

Overall wattage isn't so important as how much current is put out on each voltage.

In general, most gameboards will be fine with these minimum power supply ratings:

+5 volts, 12 amps

+12 volts, 2 amps

-5 volts, 1 amp

Other voltages like -12 volts are not used on JAMMA system boards.

Thanks for the info Peale & Ken.

The PSU is at work I'll check it out on Monday.
