    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.

    Seriously, do you really think that $3 of regulators can do the same job as $60 of power supply. Seriously?

    no i do not think cheap parts from radio shack are going to do the same job as a $60 power supply. that is not what i'm asking.

    i do not need all the features of a psu either. i want the xbox to behave like a dumb electrical accessory that turns on when 12v are fed to it.

    i don't need a psu that shuts off when my battery drops to 10.4v.
    i don’t need a psu that waits 15 seconds after the ignition is off to power down the xbox/pc.
    i don’t need to ever use the xbox power button, ever.
    i also don’t need your sarcasm.

    i'm not an idiot, i just don’t have a degree in electrical engineering.

    i am asking if there is any way to wire a xbox by sending it 12v, 5v and 3.3v it will just turn on? if so, is there a way to create these voltages with cheap parts under $20? i was just saying $3 because i was looking for a cheap homebrew solution, and was thinking that I might not need a full featured dc-dc psu for over $50.

    No. Not at the currents you require.
    The expensive part of a power supply is not the shutdown controller. It is the regulators.

    you mentioned th 3.3v, 5v and 12v but how are you going to supply -5v and -12v using regulators.
