Atx Psu To XBox Adapter

Recommended Posts

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 :)

Just an hobbyist who likes the xbox :)

The infos for the atx adapter have been around for quite some time! Sickmods once sold similar adapters but there shop is closed so i couldn't buy one. 

Inspired by there design i drew up the shematic and layout around parts i already had here.

@Crazyembereks If you want one just PM me! They are for sale just haven't posted them in my for sale section. You just need to let me know which revision xbox you got!

This Adapter and the Xbox in general isn't too picky about the ATX PSU as the xbox doesn't draw more power than any pc. Any ATX PSU even the smaller ones for office PCs should be sufficient.

The minimum specs are: (Taken from a 240v V1.4 Foxlink PSU)

96Watt power output

+5V with a rating off 13.2A

+12V with a rating off 1.2A

+3.3V with a rating off 4.8A

+3.3VSB with a rating off 0.045A

 

If you are unsure if your PSU is sufficent just let me know the brand and model so i can take a look at it!

For the 3.3vsb you are looking at 5Vsb on the ATX psu the adapter does do the conversion to a 3.3Vsb voltage! So don't get confused you won't find 3.3vsb on an ATX PSU :)

      Hello,
      I've got an xbox to which I've performed the trace corrosion repair on the past, as the buttons did not shut down the console properly (it only turned on after i applied power to the unit). I've ran it just with the power button working, until now, when I decided to go ahead and try to fix both buttons. But now it went bad or something, because no matter how hard I jump wires to traces A, B and D (C is fine on my board, and I can't find E) Please login or register to see this link. , the console simply refuses to turn on anymore.the wires are just fine and they give me continuity when soldered, but that's that. I know for sure that the power supply is perfectly fine (it never really failed). Even with only traces A and B soldered properly I can't get the console to boot anymore, and the right hand side of C7P8 has continunity to the solder pad in trace D (just saying because i'm not sure if this is how it should be, I hope nothing shorted ).
       
      Is there any other way to wire the power to the board so it'll work again? It would be really bad to have to throw it away over something like this.... I really hope someone can help me. 
      Thanks in advance.

      I'm not sure if this is the correct forum but here goes...
       
      What's the best way to clone a 2TB SATA Xbox HDD to another 2TB drive?
       
      I have an Inateck FD2002 that is a dual SATA USB 3.0 dock, that has an offline cloning feature, but every time I try to clone my 2TB Xbox SATA HDD using the offline cloning feature, I initiate the clone function, then it briefly starts the process, but the dock restarts itself. The USB cable is not plugged into it.
       
      Any help is appreciated.
       
      Thanks!

      Hey all!
      I recently completed and posted on a few Facebook groups a little project which I recently finished and one of your members recommend me come here and share it with you all, so here goes!
      The whole thing started when I decided I wanted to build a PC into an Xbox. I've done a little bit of modding here and there in the past, but nothing to this extent. Sadly I didn't make a build log as I went along, but here is the finished product for you to enjoy!
      The spec:
      Intel i5-7400 Processor running at 3.0 GHz  Zotac 4GB 1050 Ti Graphics Card 16GB DDR4 Crucial Memory running at 2400 MHz  MSi H110i PRO LGA1151 Mini-ITX Motherboard 250GB Samsung NVMe SSD 2TB Seagate Barracude Storage HDD 300w Game Max Power Supply It's got a custom water cooled loop in there too, and boots to Windows desktop in 13 seconds!
      Enjoy!
      shoe.
