Xbox 360 S PSU Disassembly

Introduction

This guide can be used for repair/refurbishing purposes

DO NOT work on the power supply while it is plugged in or while the white/orange indicator light is on. High voltage capacitors, while charged, can seriously injure or kill you. Exercise caution during this repair.

      • Remove the top shell, flip it over, and place next to lower shell

      • The two halves are connected together via the cooling fan wire. BE GENTLE when separating them

      • In typical Microsoft fashion, they've made it complicated to remove the fan wire. Not only is it wedged between two transistors it's also adhered with an epoxy like substance.

      • Using a craft knife, carefully cut through the epoxy to get the cable free. Work slowly and carefully. The thick substance and awkward angles make this a slightly tedious process

      • Be VERY CAREFUL. You can easily cut the cable here accidentally. If you cut your red/black wires you'll have to patch them. "Slow is smooth, smooth is fast"

      • Remove tape in order to remove fan from its housing unit. This also uncovers a hidden screw.

      • Remove 4 PH0 screws

      • Tape will need to be replaced during reassembly. Electrical or kaptom tape will suffice

      • Take note of the amount of filth collected on this fan. Inadequate cooling could kill your supply, or worse, become a fire hazard

      • Remove fan upper housing plate

      • Gently lift the fan up and over the post

      • The fans +/- wires are covered by a thin protective sleeve.

      • Apply some electrical or kaptom tape to patch it if necessary.

      • Initially I tried to use shrink tubing here but the smallest diameter I could get around the plug was a 3/8" tube which will not properly seal around the cable when heated

      • If you accidentally cut through the entire cable (+/- wires) you'll have to resolder them together and cover with shrink tubing.

    8. Xbox 360 S PSU Disassembly, Underside Of PCB: step 7, image 1 of 1

      • Remove PCB from lower shell and place face down

      • The metal shield must be removed in order to expose the bottom of the power supply PCB

      • To quickly and safely remove I suggest using ChipQuik on the 2 single sided through holes. Alternatively you can use solder wick

If anyone else is wondering how to turn on the 12V supply, you short the 2 small center pins together. The outer rings are ground, and the inner rings are the +12V. The two small pins are the +5Vsb and the 12V enable pin, which turns on the 12V when pulled up to 5V

Greetings, friend. Hey, I have an Xbox 360 Slim power supply that outputs 16V at 12V. Any suggestions? The power supply is an A10-120N1A board, A120R001L.
