so i found a dc to dc power supply to hook up my mac up to now i need to do the same for my xbox. has anyone ever done that.? i have a heavily modded xbox and everythin that comes out of the power supply is 12v. so in theory i could just use another dc to dc converter correct? my xbox is worth more than my (insert big expensive thing here) and i dont want ot blow it up. thx.

Most people will just hard wire in a Power Inverter via a relay. But I've read many a posts of people complaining about interferance / noise. The reason is that the Xbox being basically a computer, is very sensitive to voltage potential difference. You end up having to take it apart to ground the chassis and other components internally. To get a perfect audio / video signal. Furthermore, I've heard you need a heavier inverter due to the initial spike in current when first powering up the console.
Many people have taken thier PS2's apart and built a voltage regulator on a PCB. I've never seen this done with Xbox but here is a link to one done with Playstation. I'm not sure of the difference between the two systems, but the Xbox should have +/- 12v and +/-5v.

Someone else may be able to give you more details.
Good Luck
