How would I power a Namco System 246 board without a cabinet?

Read my old tutorial: http://www.sega-naomi.com/forum/viewtopic.php?t=5104&highlight=

Don't use the MOLEX connector for the powering up but the ATX motherboard connector. The Molexes don't always give enough juice out

 

I am using a jamma I/O board for my 246. Sould I connect the correct voltages from the 24pin to the 3 wires on the jamma harness?

Edit: Thanks for the help everyone, I now can play my 246 system without any problems. As for the solution. I used a 24 to 20 pin adapter for the power supply. Spliced the green and black so it stays on (there is an on/off switch on the power supply), and connected the red, yellow and black to the jamma harness. After doing that it would get all the way to the point of playing gameplay but not render any 3d graphics. Once I connected one of the Molex plugs directly to the dvd drive it finally worked like a charm. I will have to try my original board and see if it works now.

Just wondering, does anyone know an easy way to wire controls for tekken 4 since it doesnt support the ps2 controller?

 

Hi,

I just got a System246 Box and I get a black screen nothing else. The green WARNING led lights all the time (not blinking) and I noticed that the DVD Drive won do anything (Even opening the tray or turn on the green LED) if the Data cable is plugged.

I'm powering it with a 350W PC PSU + MAK/Supergun.

Any ideas, where to start from?

EDIT: I just plugged it in my cabinet and I get the same, so it shouldn't be a power related ISSUE.

 

Thanks
