Atx Psu To XBox Adapter

Recommended Posts

N64 freak    16

Finally found the time to test the Adapter PCBs i built to use an ATX Psu to power an Xbox.

They are plug and play to easily switch between the original psu and an atx-psu.Might be usable for casemods or laptop builds.

The adapter is built around the following basic schematic.



It properly convert the Standby voltage from 5v to 3,3v and also shifts the power_ok and power_good signals to the correct levels.

Also built a small version that can be used to build an extension cord style adapter to save some more space.

Just let me know if you have any questions about them :)

      Hello everyone,
      I recently bought an Xbox and on the first day I turned it on and it booted up fine. Days later I am now trying to turn it on again and nothing.
      No lights, no sounds. I have another Xbox and the cable works fine. 
      What do I need to do to fix this issue!

      Alright guys. The time has come.
      Here I'm gonna be adding an internal WiFi adapter to my OG Xbox because, lets face it, Wires are ugly, they get chewed by your dogs and people trip over them. and come on WiFi in an OG Xbox!!
      Heres a list of Tools and Materials you'll need
      Torx T20
      Torx T10
      Soldering Iron
      Drill with assorted bits
      Wire Cutters
      Heatshrink or Electrical Tape
      Dremel with cutting disc or small hand saw.
      Assorted files or sand paper
      Wireless bridge gaming adapter
      RP-SMA Female to Male Pigtail
      Rj45(Ethernet) Female to Male adapter
      some Motherboard standoffs with matching screws

      I got the idea from the youtube user "Thewheelman282"
      Link to video https://www.youtube.com/watch?v=3zG8DQ3Omfk

      To start you'll need to pull apart your console.
      I'm not gonna explain how to because there are Many sources for this elsewhere.

      Next you need to figure out where you want to mount the adapter.
      again I'm doing what he did in the video and mounting it to the bottom of the DVD drive.
      If doing the same you'll need to pull apart your DVD drive too.
      Every drive is different, mine is a Samsung with 4 screws on the bottom.

      Once you have the bottom half of your drive,
      You'll want to Pull apart your adapter and mark out your mounting holes.
      Now use your drill to drill them out.
      Start small, you can always make the hole bigger if you need to.

      Time to add the MoBo standoffs, I used 6 of them and cut the screw part off the ones that go inside the drive.
      Now you can mount your adapter and put your drive back together.

      Now its time to start cutting wires.
      Get your multi-meter and determine what wires you need to splice into.
      Since my adapter uses 5v I used Pin 01(Ground) and Pin 08(5V)
      Heres the Pinout for the Drive side of the DVD plug

      Next your gonna need to figure out where you want your adapters Ethernet port to be.
      I used the same location as in the video for simplicity.
      Now your gonna want to get your RJ45(Ethernet) Male to Female converter/Extension and see if it will fit. (Mine did not so i had to trim it down)

      In the process of trimming it, I nicked a few wires so I had to pull it completely apart to trace each pin with a multi-meter and solder each wire back into place.
      (Dont make the same mistake I did and take your time!!) I was impatient and rushing.

      now you can Take your dremel and start cutting the hole for your RJ45 port,
      Once cut it should look something like this.(Again I was rushing, So its not as clean as Id like it to be)

      you'll want to test fit the plug, then clean up the cuts with a file or sand paper.
      Then mount your new port to the top of the existing one. I used a few drops of Super glue to accomplish this.

      Now you'll need to drill a hole for your RP-SMA Pigtail. (Antenna extension wire)
      I chose to put it beside the Ethernet ports.
      ignore the hole by the Ethernet port. Thats for my USB ports.
      I put a piece of heatshrink around the metal antenna connector so it doesnt cause any shorts or problems once its put back together

      Its a tight sqeez but everything fits inside nicely, just be patient while your putting things back where they go.
      Now you can put it all back together so you can Admire all your hard work and enjoy your now Wireless Xbox.


      Let me know what you guys think. This is my FIRST Tutorial/Write up.
      Tried to give clear info, If you need any additional info ill be glad to help out.

      As there might be a couple people out there who want to own an Xbox Alpha Development kit but don’t want to spend the Cash they cost I thought I just write up a guide how to build one yourself with off the shelf parts!
      This is not the first guide about this topic out there but hopefully the most detailed and helpfull!
      I’m going to do this as a picture supported step-by-step guide so it should be easy to follow for anybody.
      Let’s start with the parts used in the Alpha2 Console:
      -Intel VC820 Desktop Board                                            
      -128MB RD Ram (Kingston KVR800X 18-8/128)
      -733Mhz Slot 1 CPU  (Part number SL3XN)
      -250Watt ATX PSU (ATNG Model: PS-250S)
      -20GB IDE HDD (Fujitsu MPF3204AT)
      -3,5” FDD (Sony MPF920-C)
      -DVD Drive (Hitachi GD-7000)
      -64MB Geforce3 (180-P0050-0000-A05)
      -Network Card (Intel Pro/100)
      -Soundcard (Wolfson Micronics WM9707_AMR_EV1_Rev2)
      -USB Card (Xircom Portgear PGPCI2 )
      Now on to the parts you need to buy for a basic bootable setup:
      -Intel VC820 Desktop Board
      -128MB RD Ram
      -733Mhz Slot1 CPU
      -Any ATX PSU 250Watt or more
      -IDE HDD 20GB or bigger
      -Any DVD Drive that reads self-burned CD-r
      -64mb Geforce 3 NV20 Video Card ->more details a bit later!
      -Intel Pro/100 Network Card
      That’s the minimum that is needed to get the alpha to boot the recovery CD. If you want to be able to do anything except looking at the Recovery Screen you need some more parts:
      -2 Port USB Card that uses an Opti Firelink 82C861 Chipset
      -Xbox Controller to USB Adapter +Xbox Controller
      -Wolfson Micronics Soundcard (or the recreated Version)
      That’s how my stack off parts for the alpha looks like:

      Once you have all the parts together let’s start by putting it together!
      Guess I don’t have to cover how to install the CPU, Ram, Video Card, PSU, Network card, Audio Card and the Drives.
      The end result should look like this. It’s not important in which pci port the usb and lan card are installed. BUT it is important that the lan card is installed as the Alpha won’t boot otherwise!!!

      When it’s all put together turn it on and check that it properly posts and there are no errors or whatever before continuing!
      Now on to burning a recovery CD!
      (Thanks to Borman for releasing the May2001 Alpha2 recovery! All credit goes to him for the release!) You can find the files in the download section and can simply download them.
      Here's a direct link to the files on an external Server: Alpha Recoveries and VGA Bios
      Once downloaded just use ImgBurn (or any other iso burning software) to write the May2001 recovery to a cd-r disc.
      Pop that disc into the DVD drive off your alpha and you should see the Xbox animation and should be greated by this recovery Screen afterwards:

      Now (if you haven’t done it earlier) plug in the Controller using the matching adapter and Press any button to start the recovery. The progress bar should show how far the progress is. It shouldn’t take any longer than 5 Minutes to finish and you will see this screen. Then remove the recovery disc from the drive and reboot.

      You should then be greeted by the following screen where you can set a name for your alpha console.

      Congratulations your Alpha Development kit is now fully working and ready to be used!

      I recreated the Soundcard to build a completely working alpha kit for myself as the original Alpha soundcards are as rare as the original alphas. If you need one for your build just drop me a message and I can build a couple more!

      Graphics Card:
      The video card is an important part of this build so here’s a little extra information about that part.
      The Card needs to be an NV20 Core Card with 64mb. 32MB cards might also work but we want to be as close as possible so buy a 64mb card to not get into trouble!
      I successfully tested 2 card from 2 different vendors:
      -Medion MS-8838 Geforce3 200ti
      -MVGA-NVG3T2A 64MB
      Many other NV20 core cards should work and I gladly extend that list if you used another card on your build! J
      Flashing the engineering Bios is NOT needed it is only a cosmeticall detail you might enjoy.
      The motherboard does also not need to be on a special Bios version or anything.
      You Get a blinking black cursor and no Xbox boot animation?
      ->You might have forgotten to install the Lan card, got a wrong one or your Nvidia Card is not supported!
      Your DVD-drive doesn’t spin up and you end up with an intel Network card boot/bios Screen?
      ->Something might have gone wrong with the CD you burned or your drive can’t read the cd-r!
      Could also be a problem with the boot order!  Check that in the Bios the dvd drive should be the first boot device!
      If you have any questions about the build or anything just drop me a PM!
