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) to 3.3V.
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.
