Introduzione

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.

  1. Remove rubber boots Remove T10 Screws Remove T10 Screws
    • Remove rubber boots

    • Remove T10 Screws

  2. 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
    • 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"

  3. Remove PH2 screws Remove PH1 screws Removal unnecessary
    • Remove PH2 screws

    • Remove PH1 screws

    • Removal unnecessary

    • Disconnect cooling fan plug

    • Pull wire through

  4. 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
    • 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

  5. Fan model info in case you need to search out new parts

  6. 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.

  7. Remove PCB from lower shell and place face down
    • 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

Conclusione

To reassemble your device, follow these instructions in reverse order.
