    Atom board in Car PC.

    Hi All,

    I am Hareen and I am seeing the forums related to CAR PC from last one month. As per my understudying there are two options to install a PC in CAR first one is a laptop/notebook and the other is a desktop board and processor. I found some disadvantages in desktop board related to power consumption & heat generation (especially with p4) in forums, I am thinking to install an atom board is this idea is ok or any concerns related to atom board?

    Suggest me the power supply for the atom board not laptop. (It would be better if the self-preparation guide provided).

    Thanks.

    Hey Hareen,

    Atom boards are pretty powerful boards while having great energy efficiency. Depending on your goals, I would recommend an Atom+Nvidia Ion board setup. The following website has alot of boards to choose from, personally I love the Asus, and Zotac boards but they are all great.

    This page has all of mini powersupplies:

    The power supply here is great for an atom board as long as you're not running too many peripherals:

    I think the Atom board is the way to go. Worked great for me.

    Hi, last year I studied this carefully and decided to go with one of the most powerful an Atom based chips/boards the Intel D525MW.

    Here are the key factors that drove my decision:
    -- Are powerful graphics important? (e.g. 1080p video, games and Win7 Aero)
    -- Does your car have enough juice (amps) to run a 30-50+ Watt TDP board?
    -- In your install location, will heat and space be an issue?
    -- Tiebreaker: non-Atom boards are around 30-75% more expensive - is the difference worth the gain given there is a new generation of boards every 18-24 months.

    How I made the call:
    -- I looked at the ratio of power consumption to benchmark score. I considered the new AMD low power platform but the performance is not there yet.
    -- I eliminated non-Atom processors due to the high power consumption and heat.
    -- The D525 uses 13 Watts TDP. It runs Windows7 very quickly and nicely - its snappy....as long as you turn off all the Win7 aero stuff. The weakness of the Intel's D525 based board (D525MW) is the graphics. It will not run DVDs at 1080p, 720p is all it can manage.

    Finally: As MumbleFish notes, get one with an ION graphics processor if you are wanting Win7 Aero and are going to do anything more than basic DVD 1080p; e.g. games.

    I went with the Intel board because I had poor luck previously with Jetway's board quality and because graphics were not a top priority. I've been extremely happy.


    Hope this helps,
    John

    it really depends on your usage.

    i have run both a atom board and a pentium dual core. i also run audio processing-- which is very cpu intensive..

    some other members have found the atom boards to be a little slow even with standard usage.

    also, something to keep in mind is that centrafuse fe does not use any graphic processing, so the ion chipset is useless in that regard.

    the atom boards are a great start to a carpc-- they are cheap, and low power, but like everything, if you start adding tons of features, that cheap/low power quickly becomes a negative instead of a positive.

    careful with those. those need a different type of power supply-- one that can supply 18.5-19v through a small barrel connector. the common brands for this are the carnetix 1900/2140, or the dc-dc-usb.

    Mini ITX boards are great and offer a lot of goodies, but if you want something smaller, 3.5" Single Board Computers such as this one are a good bet.

    Mini ITX: 6.7" x 6.7"
    SBC: 5.7" x 4" - and that's with the RAM and hard drive installed. The entire board with RAM and HDD is the size of a 3.5" desktop hard drive.

    I think the current draw for my board and LCD monitor is less than 36 watts.

    IMO, Mini ITX boards and enclosures are too big for the car environment. When you consider that cabling adds yet another 1.5-2" to one dimension, where do you stick it all?

    I had mine in the trunk, next to my amp. That's where I'm putting it again, when I complete my remodel and upgrades.
