We are pleased to announce the distributor for these is Highway Entertainment. http://www.highway.net.au/news/introducing-the-sega-to-atx-power-supply-adapter-kit/450.html
Over the last few months I have been working on a adapter board to allow Sega power supplies such as the Model 1 and Model 3 PSU, be replaced with a generic ATX power supply without needing to modify the wiring loom. These power supplies, which are no longer available, used to cost over $400 USD from Sega.
This kit will include these two boards and a 30cm IEC C13 to C14 cable. It is expected that these will be available for sale around the beginning of August 2015.
These power supplies were used in games such as Virtua Racing, Star Wars Arcade, Virtua Fighter, Wing War, Sega VR-1, Dennoo Senki Net Merc, Virtua Fighter 2, Manx TT Superbikes, Sega Rally Championship, Sega Rally Pro Drivin', Sky Target, Virtua Cop 2, Dead or Alive, Dynamite Baseball, Dynamite Cop, Pilot Kids, Virtua Fighter 2.1, Motor Raid, Zero Gunner, Boat Race GP, Virtua Fighter 3, Virtua Fighter 3tb, Sega Bass Fishing/Get Bass, Scud Race, Le Mans 24, Scud Race Plus, Harley Davidson & L.A. Riders, Fighting Vipers 2, Sega Rally 2, Ski Champ, Daytona USA 2, Daytona USA 2: Power Edition, Dirt Devils, L.A. Machineguns, Spike Out, The Lost World: Jurassic Park, The Lost World: Jurassic Park Special, Virtua Striker 2, Virtua Striker 2 Version '98, Virtual-On Oratorio Tangram, Star Wars Trilogy Arcade, The Ocean Hunter, Emergency Call Ambulance, Magical Truck Adventure, Spikeout Final Edition etc etc...
After lots of effort things are finally coming together and the boards should be available sometime in the next couple of months.
The DC Board has indicator led's for the presence of 3.3v, 5v and 12v.
I have added a connector labelled Astro to the board for the Service, Test, AF+ and AF- for Astro City.
Below is a picture of an early prototype on the right and the final finished board on the left.
The kit will include 2 boards. One board will accept the existing 110V plug in, and will have an IEC female output to go to the ATX PSU. The second board will take the 20 or 24 pin ATX plug and present the same connectors as you get on the original power supply. There are quite a few power supplies that can be replaced with this kit.
Power supplies like those pictured below can be replaced.
Note: Some power supplies do not have a 3.3v connector. If that is the case then the connector is simply not used.

This unit is common in Astro cabinets and has a couple of extra wires which we have also included on the replacement board.

The circuit boards arrived from the manufacturer, and they look fantastic. This board has been made with a thicker substrate than normal (2mm) and also has heavier 4oz copper to handle the high current required.
The board powered with a 20pin ATX psu. The board will work with 20 pin and 24 pin ATX Power supplies.
Green Led = 3.3v, Red Led = 5v and Yellow Led = 12v

The finished product. The AC board has some transparent heat shrink over it to provide a little bit of protection from it being put on top of a metal case, or someone touching it while its live.
Below are some photo's from the an installation by Aaron in New Zealand who was kind enough to send these photo's back.
