So I need to bridge white to black, think it's a 1.6v

But do I also need to bridge blue to black to keep it powered on? It's going to power one fan for a 3D printer using the molex connector

I would suggest you use a 12 volt plug back (Wall Wart)type supply over a Xbox supply it's safer.

To make a Xbox supply turn on you need to supply a 3.3 volt signal to the PowOn pin, On a version 1.2-1.4 Delta supply you would connect the White (PowON) and Gray (3.3. Standby) and a foxlink connect the Green (PowON) and the purple (3.3 volt standby)

The PowOk is from the main board of the Xbox so unless it's connected to a Xbox it will be 0 volt

Do not connect the Black to any other wires

Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

I have like an external molex PSU for powering hard drives, but it refuses to supply power with fans unless it's broken.

Also threw away all my old PC power supplies, so the extra xbox is coming in handy.

Guess it's very not standard then, since on a normal ATX PSU you just have to bridge green with ground?

It's powering a PC fan controller so I can easily change the speed of the fan.

And it's 100% a 1.6, as it's missing the 4 wires in the middle.

Looks like it's white/blue for the 1.6 PSU then?

Yes on a PC PSU you ground the PowON wire and a Xbox you power it.

I have not tested a 1.6 PSU out of the Xbox but you could try at your own risk linking one of the 4 orange wires (5 volt standby) to the PowON (White) and that will turn on the 4 pin molex connector.

I am not sure if the PSU will like the 5 volt to the PowON instead of 3.3 volt.

      It has literally been over 10 years since I've played it. One of the bootup screens says "Xecutor2" at the bottom, so that tells me that much at least.
      My main question is the three (3) dip switches on the front of the console. Someone else installed it for me, and I forget what each of them does.
      I think that the left-most one controls whether or not the modchip is active; you wanted to toggle that one off if you ever went onto XBox Live, I think.
      Can anyone help?

      A friend gave this modded Xbox but didn't know much about it.  I've had soft modded ones. but don't know much about the hard ones myself either.
      It has a larger hard drive.  When you turn it on it gives the 09 error and ring flashes red and yellow.  Someone told me that button should be held on the controller when you turn on the Xbox but isn't sure which ones.  Would that cause the 09 error?  
      Thanks for any help.

      In the Build v1.1.8\Extras Disc\Documents folder their is a txt file that says:
      You can run the "Xbox Softmodding Tool Extras Disc.iso" from the Xbox HDD.
      What happens if I run the virtual image and wish to restore xbox to factory using that image.  Will it corrupt the drive as the image is being read off the same drive?  Or being a virtual image it is stored in a temporary location and once the xbox is restored it is deleted and won't interfere when restoring.
