400-5198-01 PSU in NAC, Mvs 4 slot/Naomi?

[TMallu]

This is my PSU in Sega NAC, does it have enought juice to run mvs 4-slot? or Naomi with Capcom IO?



thanks.

It should do. Have you measured the output voltages?

[TMallu]

Ok, thanks. No I haven't.

guess you still don't trust your multimeter, am I right?

It is labeled so very nicely. How much juice to you need?

It should handle a MVS 4-Slot without any issues, but unless you are running the Naomi with the separate JVS power supply it is not going to power it up through the Capcom I/O board.

My power supply board blew out and I modded in a standard Happ PS to replace it (without cutting the cabs wiring). It doubled the current on the +5 volt. Here is how I did it : http://forums.arcade-museum.com/showthread.php?t=258326". The modification instructions are at the bottom of the thread.

If you turn the +5V adjustment screw all the way up you might get some life. The adjustment is on the top of the PS in a little hole, right above the wire connectors. Mine wouldn't, but it doesn't hurt to try it.

Just don't be surprised when you only get a black screen. :p

I have a NAC with the same power supply. My naomi works fine through a capcom I/0 board with carts.
I also have a Net Dimm and had to convert an ATX PC power supply with some JST plugs and that works great to.

Carts only you should be fine

Is this PSU sufficient to run CPS-3 with cd-drive?
