Today on 0084 A battery powered 486DX2/66 setup and a 386 motherboard with a fancy BIOS I learned about PicoRC: PicoPSU on Retro Computers and also ATX4VC: ATX Power on Retro Computers.

Fuse access
I rewired my ATX power supply breakout board so that I would have ready access to the fuses. Probably gonna blow a few of those! The fuses are 5A 250V fast blow (F5A250V) so I can’t draw more than 60 Watts (at 12V). You can see in the previous post and the picture at the bottom of this post that the terminals used to be connected above the fuses, impeding access.
The ATX power supply breakout board is a Geekcreit® XH-M229 Desktop Computer Chassis Power Supply Module ATX Transfer Board Power Output Terminal Module.
This is the new setup:
This is the old setup:
ATX power
I made three power cables today. Blue for 3.3V, Red for 5V, and Yellow for 12V. I used 4mm lugs and bolted them to my ATX power supply breakout board. So now I have some handy power rails on my bench powered from an old computer power supply.
v1.0-v1.1 motherboard power connector
So I’m fishing for an answer to the type of power connector used on the v1.0 and v1.1 Xbox motherboards: v1.0-v1.1 motherboard power connector so hopefully someone knows and can help me. It’s some type of “ATX” thing I’m sure but what I really need is a DigiKey part number. :P
Diagnosing non-functional RD6006W
So I have a Geekcreit® XH-M229 Desktop Computer Chassis Power Supply Module ATX Transfer Board Power Output Terminal Module which I’ve plugged into an old ATX power supply. I’m using that to power a RD RD6006 RD6006W USB WiFi DC DC Voltage current Step-down bench Power Supply module buck adjustable converter multimeter 60V 6A. When I assembled my RD6006W and powered it up, “nothing happened”. I wasn’t sure where the fault was, but I used my new OWON XDM1041 Digital Multimeter and my TENMA 72-10505 Bench Power Supply to narrow down the problem: I’ve blown the fuse for the 12 volt line on my ATX power supply. So gonna replace that soon. In the mean time I’ve been testing my RD6006W by powering it off the 5 volt line. So far so good.
Molex power cable
I’m getting a RD6006W USB/WiFi DC voltage bench power supply with the S12D case. I’m gonna power it off an old ATX power supply. So I needed a molex to banana plugs cable, and I made one:
I threw a DC barrel power jack on the 5 volt line. Finished with heat shrink tubing, my new favourite thing.
