I believe you can make a NAOMI PSU with a standard PC 200W PSU.

Any need for the separate voltages 3,3V, 5V and 12V? How can I make this? Or maybe better: where can I buy one?

This will work, right?

I've got a spare NAOMI PS.

$50 shipped in the US.

LMK if you are interested

Thanks

I live in Europe, so shipping will be expensive.

@maxchainsplendid: I'd love to make a NAOMI PSU. How many Watt do I need? 250W enough?

Where can I buy the correct Molex connectors?

Yeah man, 250w is fine - for the JST connectors, I suppose you could salvage the ones from your Astro PSU, no? And for the female ATX CN, I just desolder them from old PC mobos :]

Here's a link to the PC ATX pinout: http://pinouts.ru/Power/atxpower_pinout.shtml

And you can find the Naomi mobo pinout here (at the bottom of the page):

The Astro PSU doesn't have JST connector for NAOMI on it. I need to buy it. But which connector do you mean from an old mobo? I only need one power connector for NAOMI without GD-rom I think? Only the 8pin JST connector.

One other thing I was thinking about. My PSU from my New Astro also lights up the lamp on top of the cabinet. Maybe I can remove this from the PSU and the NAOMI has enough power. Is this a scenario that could work?

Double checked and no JST NAOMI connector in my cab. It's an Astro City PSU, which doesnt have those connectors.

So I need a 3,3v and 5v capable PSU and 1 JST NAOMI connector?
