    stupid noob here and need some help

    okay i picked this computer up off ebay:
    http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5157476522
    i bought a 7 inch touch screen monitor too. I know how to do all the audio hook up to the computer and touch screen crap.

    my main question is what do i need to power this computer? like i read about power inverotrs and such, also automatic shutdown/power up, and power supplies. is there something i can buy that has basically all these components built into one? Thanks.

    Now, now. We're all newbies at some point.

    I'm not going to put a "search" graphic in this post, since you've probably already got the idea.

    As for an all-in-one DC-DC PSU/startup controller, I recommend the M1-ATX. I've got one hooked up to my M10k, and it works a treat. Compare its wattage supply w/your requirements, and see if it'll work.

    Failing the M1-ATX, you *will* need a DC-DC PSU that pust out +12v, +5v, and (I think) +3.3v, as well as some negative voltages as well (again, I think...). Check out the various PSUs available at the mp3car.com store, and find one that'll supply the power you need.

    You'll also probably want to get a startup/shutdown controller, like an ITPS or some such like, but I haven't used them, since that functionality is already on my M1-ATX.

    Check out the "Power Supplies" forum for the latest info.

    Best of luck on your new (and expensive, if you hadn't noticed already!) endeavour.

    i kow what the search button is and i know how to use it. ANd i did look in the store... instead of lecturing me on that you could have helped.

    anyways you said the all in one piece that costs 75 bucks? Basically i am still confused...

    all i want is something that will do the auto start up and shut down feature for the computer i showed in the link. Which components do i NEED to have for automatic start up/shutdown. Does those things include what is needed for a 12v battery power source?

    I have read through everythign but i am a complete noob when it comes to this stuff and i can read for another couple hours but i jsut dont really understand what i should buy/get? Any help would be greatly appreciated. Thanks.

    orzech: I too am a noob at this but fortunately I have an understanding of some of this stuff

    You will need a PSU that has DC-DC. Opus are probably the most common ones. I currently have an OPUS 150watt power supply.

    This unit connects to the cars ground, permanent live and ignition live (ACC). When you start the car, the ignition live goes high, the opus picks this up and switches the computer on.

    When you turn off the car, the ignition live goes low and the opus shuts down the PC. This can be a timer set by jumpers on the board.

    The link that rubicon posted is a perfectly sufficient psu as long as your power requirements are not above 90w.

    Have fun

    oh no - isnt that guy he got his PC from the guy who was banned for hacking the mp3car site???

    I have not read past the 1st line of your post but you will find some details on powering your PC on this forum somewhere.

    I have my fingers crossed your PC is ok! and finally.....

    Given that the PC you got is 1Ghz celeron you would probably be alright with a 90w power supply. You will just end up replacing the power supply that is already in that computer with a DC/DC power supply.


    Basically you want something with a startup and shutdown conrtoller and something that will survive cranking your engine when you start the car. The OPUS models are great, but do not have the startup/shutdown controllers in them, the M1-ATX is probably your best bet for an all in one just dont add to many extra USB devices and you should be fine with power consumption, or you could go with a different route of getting a CarNetix ($100 for 80w) which is basically a regulator with a shutdown/startup controller and the ability to survive a crank and pair it with a small cheap ($30-40) PS for your computer. These cheaper PS's won't work by themselves all that great because they arent all that tolerant of the wide range of voltages your car can produce, nor do they have all the bells and whistles, and since you would be providing them with stready 12v they will work great.

    Any way you go just make sure to have a nice heavy wire running up to your battery. Figure out how many watts you are going to use @ peak, divide by 12 to get amps then look at this chart to find out what wire you should use!

    If you'll read the post again, you'll see that I did help. Would you rather that I held you hand and said, "Buy this. Its what you need."? If thats the case, then there's this bridge I'd like to sell you...

    And if you *had* done any reading on PSUs prior to posting your initial question, you'd have found the answer right quickly - as I, and I'm sure many others, have done. But you didn't, and you asked for help. Fine. But when help was given, you went special ed on me.

    So good luck with your project and the confusion. I recommend you get used to the way folks interact here, otherwise you might get your feelings hurt, and the last thing anybody here wants to do is hurt the feelings of a noob.
