  • How's My Planning Look?

    After having read pages and pages and pages of this forum for months now I think I have come up with a quality set-up for a CarPC in my truck. But I would like some other opinions, being a newb and all, to see how my proposed set-up would work out.

    I've made a wiring diagram that if you wouldn't mind I would like for you to review and tell me of corrections I need to make. FYI, I know that I didn't include speaker wires or remote wires as I thought they would only be a waste of space on the diagram. Also FYI, the Grandtec 2000 oddly enough is powered by a USB port and I will be using it for future installation of headrest, visor, etc monitors. The Grandtec 2000 will accept one VGA input and output one VGA and one RCA, I will eventually use the RCA and a video amplifier if I do add the mentioned extra monitors. I plan on being very conservative on wire choice so I will be using 0 AWG wiring for the "Big Three Upgrade," and all power wiring up to the power block and ground wiring from the ground block to the ground location. I'll probably use 2 AWG to and from the power/ground block to/from the amps. Then I'll probably use 8 AWG to and from the M2-ATX PSU and the power/ground blocks. As I said I want to be very conservative with my wiring choices.

    Here is a list of components I will be using for the CarPC set-up with approximate prices.

    $45.00 Intel Pentium M 1.4GHz SL6F8
    $50.00 Biostar P4M80-M4 Motherboard
    $43.00 WINTEC 512Mb DDR400 PC3200
    $65.00 Hitachi 160Gb 7200RPM 8Mb Cache
    $100.00 Audigy 2 NX USB Sound Card
    $270.00 Lilliput 8" Touch Screen
    $90.00 M2-ATX 160W DC-DC PSU
    $60.00 Grandtec Ultimate 2000
    $80.00 Super Slim External DVD Writer
    $60.00 GlobalSat BR-355 GPS Reciever
    $25.00 USB Hub
    $30.00 USB 1Gb Pen Drive
    $30.00 USB Gamepad
    $35.00 Wireless Keyboard/Mouse
    $50.00 Lola RF Remote

    Totaling $1,033.00

    (Excluding random expenses I'm expecting... wiring, heat shrink wrap, electric tape, solder, materials to build my PC case, bondo and JB weld for the Lilliput in the dash, etc)

    I've also done some power calculations to make sure the PSU can handle all the stuff I'll be adding. Again I was conservative in these calculations (but once again, thats a good thing).

    I found out the M2-ATX PSU puts out
    8A (96W) = 12V Rail
    8A (26.4W) = 3.3V Rail
    8A (40W) = 5V Rail

    I looked up the maximum power draw for the major components that will be on my PSU.
    5V Rail
    DVD Burner (5VDc x 2A)=10W
    USB 7 Port Hub (5VDc x 3.5A)=17.5W
    Audigy 2 NX (5VDc x 1.5A)=7.5W
    Total 5V Rail = 35W (So I'm under by 5W)

    12V Rail
    Lilliput Touchscreen (12VDc x 0.83A)=10W
    Pentium M 1.4GHz SL6F8 (12VDc x 1.83A)=22W
    Total 12V Rail = 32W (So I'm under by 64W)

    Once again, those are worst case power draw numbers, if those are drawing all the power they can, so I'm not expecting to draw that much power but do you think that being under by 5W on the 5V rail and 64W on the 12V rail is enough?

    Here is the wiring diagram (click the thumbnail).


    To everyone that actually read all of this and responds helpfully thank you so very much, this forum has been a great help in my planning. I went from wanting to use an inverter to all of this planning.

    Looks like the planning paid off.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

      excellent work. There are a few newbies that could learn from you. Looks like you shouldn't have any problems.

        Thanks for looking over my plans for me. I really appreciate it, this forum has been a huge help. I've probably spent 3 or 4 months trolling the forums reading as much as possible. Now that school's out I can get a move on it and start buying the parts and building it.

        I actually just decided to make a revision to though, it will end up costing a little bit more, but I wanted a Turion Moible processor instead, different motherboard, and same hard drive but SATA instead of ATA. I found out that the Pentium M processors don't really like desktop motherboards, so AMD seemed like a better route to go. Especially since many websites have said that the Turion Mobile is quite a bit more desktop motherboard friendly, and it only uses 3W more.

        Revision
        $145.00 AMD Turion 64 Mobile MT-32 1.8GHz
        $55.00 Foxconn 760GXK8MC-RS AMD Motherboard

        $72.00 Hitachi 160Gb 7200RPM 8Mb Cache SATA
        $100.00 Audigy 2 NX USB Sound Card
        $270.00 Lilliput 8" Touch Screen

        12V Rail
        Lilliput Touchscreen (12VDc x 0.83A)=10W
        Turion 64 Mobile MT-32 1.8GHz (12Vdc/2.083A)=25W
        Total 12V Rail = 35W (So I'm under by 61W)

          Everything looks good. Only suggestion is going with a better brand MB and Nvidia 6100 chipset. I would suggest $55 Gigabyte GA-K8N51GMF (what I am using) or something from Asus.

            Looks like a good mother board... Just got done reading some good reviews of it, doesnt cost much more money, it has a lot better onboard video... I'm a customer.

            And I decided for hard drive compatibility with my home computer... I'm not going to use a SATA HD.
