    M1 to power....

    Hi,

    I've my carputer ready to fit, consisting of :
    Intel P3 833MHz motherboard, not sure what make
    Seagate 7200rpm 40 gig
    264MB RAM
    DVD/CD-RW drive
    Tiny processor fan and 13cm case fan


    Would the M1-ATX 90w be enough to power this load in car?

    the DVD may be a problem, go for an external USB device with external power source if possible

    ho, it's only a regulator, you also need a power supply to run your pc
    M1 atx will easily be overloaded powering a standard HDD and DVD, it will be overloaded if you also run your LCD

    where did you find 264 mb of ram?

    Anyway, a M1-ATX has 90 W, but you can't just look at what you are powering and say OH, I need 70 Watts so I'll be fine. That is wrong. If you look at the specs, each line has a maximum Amperage that it can carry. http://www.mp3car.com/products/M1-ATX/M1-ATX-specs.pdf
    So what I'm saying is there are 3 lines that I will talk about the 12V, 5V, and the 3.3V line.

    First you should know voltage times aperage = Watts (power)
    The 12V line can do 2 Amps= 24 Watts (a single 7200 RPM HD can demand up to 30 Watts!!!(Thats only a peak measurement tho(yay for parenthetical expressions!!!)))
    5V line has 10 A = 50 watts
    and 3.3 V outputs 10 Amps = 33 watts
    So actually if you add that up you get 107 watts of power. But you can also see that if you want to run a CPU and A motherboard that primarily ge their power from the 12V line you are screwed. mini-box even says that this is designed for low power systems that are powered off of the 5V line.

    Check out this website: http://www.ohmygodmyarmfelloff.com/MP3Car/PSUpower.asp
    for the rail breakdown of whatever system you are trying to set up.

    BTW an LCD is about 6-7 Watts (i think) all of it on the 12 V line so that will add a .5 Amp draw on you power supply.

    I learned all of this the hard way after burning up 2 m1-Atx. Now I'm modding a M!-ATX and Carnetix P1260 to work together so i can have a big 12 V line

    Anyway good luck and let me know if you have more questions?

    Should I turn this post into a FAQ?

    opus is definitly easier to setup. I am poor so i went with the m1-atx, but in the end i only saved a few pennies. the common theory is that you end up buying the opus so you might as well buy it first and save yourself the frustration
