Power Supply Pinout (Xbox Original)
For more details on the pinouts (provided below) you can also checkout https://xboxdevwiki.net/Power_Supplyīģŋ
The power supplies for the Xbox all work in the same way.
- Output a standby voltage of 3.3V for v1.0 to v1.5 / 5V for v1.6
- Listen out for the SMC sending the Power ON (white wire) low (from 3.3V or 5V) when power button pressed.
- Enable 3.3V, 5V and 12V rails, and send Power OK (blue wire) to 3.3V.
- SMC should listen for this Power OK voltage and then reset/start console.
To identify which version you might have before opening you can check the date on the serial number on the bottom of the console.
Manufacturer Date | Model Revision |
|---|---|
2001 -> 2002-07 | 1.0 |
2002-08-18 -> 2003-01-25 | 1.1 |
2002-12-01 -> 2004-03-15 | 1.2 |
2003-03-02 -> 2003-07-26 | 1.3 |
2003-07-20 -> 2004-04-10 | 1.4, 1.5 |
2004-03-14 -> 2004-09-06 | 1.6 |

NOTE: Colors of the wires can change between revisions but the positions will always be the same.
For example some v1.6 power supplies have the 5V standby wires as orange, others as red.
