Complete Idiot's Guide To Building A Naomi ATX PSU/Adapter

[OldFoo]

To provide another possible alternative for people, I made this one in about an hour.



I bought the 20-pin female connector from newegg for $4, the naomi pins/plugs from segashed. The wire came from a busted power supply. The red connector sleeves and on/off button are from wal-mart. There are fancier on/off buttons, but that was the cheapest one, and I like cheap.



I also made a gd-rom adapter, forgot to take a pic of it, but its nothing special, just a modded molex adapter.



With a little time, a decent stripping/crimping tool, and research/testing (really have to stress that like the original post does), there aren't too hard to make.



Hope this helps.

hi, i want to use an atx psu to power my naomi 1 and GD rom, but i only have Y cable with the 8 pin JST and the GD rom connector(the GD rom power harness), i'm not shure if this goes well, or i need a 8 and 6 pin JST connector cable plus the GD rom connnector...



can anyone tell me if i must buy it?



if i have to, there is someone who will sell me it ?



thank you

You have this?



If so, you can cut off the female receptacle and add (crimp or solder) an ATX connector and run mobo+gdrom drive. Of course, having a 6-pin connector besides the 8-pin would be better as it would help reduce voltage drops but even with just the 8-pin one it should be OK.



But if you want to save yourself the trouble I have fully wired ATX adapters for mobo and gdrom drive ready to ship:

Considering paypal fee's are extremely high for a small transaction etc.



Anyway I got no min order, so it works out cheaper here for people in the UK.

ok thank you.



MKL, hai PM!

This was my first chance getting to solder something and I found making the adapter was quite easy this way.

Is it just me or was the gd-rom's power pinout not mentioned? Luckily I found it over at this topic: http://www.sega-naomi.com/forum/viewtopic.php?t=127

I think its also worth noting that after you solder wire to the JST pins, it's a good idea to crimp the two inner flaps closest the the pinheads down. I left the larger outer two sticking up though.

I have an ATX supply running my mame cab. Could I split off the correct voltages to run off into the naomi but still keep the atx supply available to use for the mame pc ?



Obviously I would never run both at the same time I know that won't work, but if say the Naomi power cable was unplugged could i make the pc still turn on ?

edit: looking about also would it not be possible to use a sata power port to power up the naomi, it has the 3.3v 12v and 5v lines. Then I could have both powered up at once ??
