    you can use an inverter...but it would be better to go with a DC/DC power supply if possible.
    Inverters tend to be less efficient and create noise.

    yes you can convert and existing ATX power supply. It has been done, but the details are very sketchy. Unless you are really good with electronics, I would suggest that you not try this and just buy and existing DC-DC PSU. There are many to choose from.

    Have a look here: http://www.mp3car.com/vbulletin/advfaq.php This will give you a ton of info on what your options are.
    Never let the truth get in the way of a good story

    Well....you tell us what you think. The second entry in the faq link that Meddler sent was "How to pick a power supply". What conclusions do you draw after reading it?

    Also, what kind of monitor will you be using in the car?

    That doesn't tell anyone anything.
    All sorts of screens will all manner of compatibility are sold on Ebay each and every day.

    i wanted to go with the dc-dc power supply but i just don't think it has enjough juice for this computer.
    I suggest doing some actual calculations rather than making blanket assumptions.
    And there is not "the dc-dc power supply". There are several models available with different functionality.

    the radio i got also has touch screen i wanted to use the touch screen on the radio compatible with the computer but everyone ive talked to has said it can't be done
    It's possible.
    However, it's highly impractical and out of the budget for the vast majority of us, so "impossible" may not be technically accurate, but it might as well be....

    i have three amps with two 8 inch subs 800watts plus 2 12 inch subs around 3000watt for both basically i have a killer syster thats why im so worried about how much power my computer will need i will post pics *** soon as i get all the info to put it all together and if you have all guessed im a newbie and love doing my own thing i ask research and ask again so its all right and you guys are everytime all right
    I'm more worried about your hideous walls of text.
    Please use some capitalization, punctuation and sentence/paragraph structure to separate and organize your thoughts and ideas. It will make others more willing to lend assistance.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Start doing some research.
    Find out if the motherboard in your Dell model is TRULY ATX compliant. Dell has this habit of using the same connectors but ot wiring them to meet the standard.
    Some quality google-time and poking around Dell's support site should yield that answer.

    If the motherboard is truly ATX compliant, then you've narrowed down your DC-DC options to ATX compliant PSUs.

    Then calculate the power draw for all your hardware. There are instructions in the FAQs.


    Sure, I could tell you what power supply would work well.
    But I think you'll be far better off choosing one based on the power draw of your system. You know you chose correctly and get a warm & fuzzy feeling of accomplishment.
