I have a V1.4 box and the PSU died so i bought a 1.6 because i was under the impression that 1.2-1.6 used the same type. I see now that this is wrong in reading around here it looks like they changed a wire from 5v to 3.3v is this true? What versions of PSU can i use? also if you please have one that will work please let me know i have a request in the BST right now thanks for all your help

You can use the power supply from version 1.2 to 1.5 Xboxes.

Thanks, is there a way to convert a 1.6 to work?
