    This makes no sense to me. Maybe it's because I've only had one cup of coffee this morning.

    The M2-ATX already outputs stable 5v, so I don't understand what you're looking for.
    Are you expecting to get stable 5v straight from the car battery, bypassing the M2ATX? The car battery outputs 10.5-18v (depending on battery and how well it's charged and such).

    If you're overloading the 5v rail on your M2ATX, perhaps a point-of-load power supply to power 5v devices is what you need. Opus makes one that's sold int he store here.
    Have you looked in the FAQ yet?
    How about the Wiki?

    i don't know if my m2-atx (160w) is enought for this:
    athlon xp 2000+
    mb audio/video onboard
    3.5 hdd 40gb
    tv/radio card
    gps usb
    bluetooth

    and so i'm thinking to use the 5v directly from the car battery...

    another question:
    it's possible to use 2 m2-atx? i have two of this psu

    Yes you can.
    Get a stable 5V and use it to power HD/DVD drives. Look for 5V POL (Point of Load) in the forum's store.
    That is how my Sproggy 4.5a was built. 2 Separate 5V (15A and 5A) rails and 2 separate 12V (5A each) rails. Each of the the 5A is totally isolated (output side) and use it to power the HD and DVD ROM.
    If you are using AMD CPU, the CPU get it power from 5V rail and M2 may not be able to power it.

    Have you even considered how you're going to get 5v from the car battery?
    Again, there are products that will give you 5v for devices that require it.

    another question:

    Don't know. I'd ask the the folks at mini-box, who design and distribute this PSU. It's a new product, so I doubt that anyone has even attempted it yet.

    This is usually true (for older boards), but not always. If the mobo has a 12v square connector, there is a good chance it runs off the 12v rail.

    While the M2-ATX is rated 8A on the 5V rail, it can actually do about 15A (tested this in the lab). The only problem is that it will get hot-hot.
    If you blow some air over it, you should be able to remove some heat.

    I doubt that your setup will consuime more than 6-7A on the 5V rail....
