ATX to jvs power splitter?
And what else?
adjustable 3.3?

I don’t know but I’ll take 3!

With a switch?
Winner, winner, chicken dinner!
So yeah, I've crimped a NAOMI to ATX power adapter before and it is not the business. Also, I have crimped a volt meter to a JVS power supply before. That isn't the business either.
Just before the pandemic hit, I got a little proficient with PCB design software. Many ideas were brewing before then, I just didn't have the skills or even knew where to start. @Frank_fjs turned that all around for me and a lot of others with his opensource projects. Anyhooooo, one of those ideas was why not combine both of those crimpin' functions together in one simple PCB? Because you know, crimpin' ain't easy.
But yeah, for those that want a voltmeter on your JVS PSU, there is a 3P3T switch that allows for metering all three voltages on a JVS PSU using only one meter. You can also use it to power your Naomi with an ATX PSU. Sun PSU's are harder and harder to find these days. And crimping an adapter is no bueno. Simplest possible PCB to make. Any interest for it from anyone?

I can do that. But someone point me out to the Viewlix connector information and pinout. I don't want to fall to the darkside looking up Viewlix info like @jassin000 has 
.
Two copper pour planes. One for GND and the other for +5vdc. Will probably panelize this 4:1 for good measure.

I’m down for 3
Nice work
Nice work
down like a clown charlie brown. for 2 of them.

Brown = 3.3vI don't want to fall to the darkside looking up Viewlix info like @jassin000 has
Black = DC Ground
Red = 5v
Yellow = 12v
These are the wires/positions populated by the stock VLX JVS harness.

The VLX & AWSD cabs use a 5-pin JST VH for AC power input (no earth ground, only L/N).
The harness I showed above is two (1x12pin, 1x8pin) molex mini-fit jr on one side, needed for this harness to connect with the Wei Ya PSU.

Right. I don't need AC power however. I need the DC connector series.
Need the connector series that connects into whatever connector is pinched between your fore and middle finger in that pic you posted earlier. That is the connector we would want to plug into this adapter PCB.

JST VLs on JVS I believe (I've never actually crimped one).
*Update*
Yup JST VL 8P and JST VL 6P, so say the Naomi manual.
1: NC
2: 3.3v
3: 5v
4: 12v
5, 6, 7, 8: DC Ground
1: NC
2: 3.3v
3: 5v
4, 5, 6: DC Ground
FYI, you may want to include some type of single DC ground wire connector.
Whatever cab you install the JVS PSU inside should have its DC ground bridged with the cabs internal PSU (see B1 on the VLX harness).
