    Xbox run off 12v

    Can i just use regulators to feed the xbox 12v, 5v and 3.3v to always be on when it sees power?

    i do not want to use an interter, and i lost my opus 150 psu. i want the xbox to turn on like a dumb 12v accessory when a relay sees 12v. i also do not want to use the xbox power button or cd-rom, ever.

    SO, can i just go to radio shack this afternoon and spend $3 or do i really have to buy another dc-dc?

    i lost my opus 150 and dont want to buy another one. i also refuse to use an interter in my car. i want the xbox to just behave like a dumb 12v accessory.

    so no interter, no dc-dc psu, just a fused 12v line to regulators to the xbox at 12v, 5v and 3.3v

    possible?

    What do you think you're going to buy for $3 that will power an xbox?

    voltage regulators. maybe i'm thinking to simply, but the thing does run off 12v, 5v and 3.3v, right?

    I don't think you're going to achieve what you want to do with a handful of $3 regulators from Rat Shack.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    if the xbox sees 12v, 5v and 3.3v, why does it matter whether it comes from a psu or a few regulators knocking down 14v from a vehicle? if you look at a dc-dc power supply these days, it's VERY tiny. some are so small the board is built into the atx connector.

    small psus

    dc-dc psu's are nothing these days. so small the board fits in the end of the ATX connector.

    i just want to save 50 bucks and i dont want to wait a week for shipping.
    i think a few voltage regulators will work.

    Yes you are. What was the current rating of this $3 worth of regulators? How much current does your xbox require?

    Yes, I'm spoonfeeding you the questions you need to answer in order to realise that you are hugely mistaken if you think $3 woth of regulators is gonna solve your problem.
