    M2-atx 160w

    Is it possible to use a brick with this supply?
    I need to run off the batts when I'm mobile, But we I'm
    stationary can I remove the batts and run a brick?
    Also if this can be done, what size brick would I need
    so I don't damage the power supply?
    Thanks

    I may have found my answer in the form of a Radio Shack power supply.
    Has anyone tried this setup for temporary power solution?

    There aren't many power bricks that put out the amperage needed for the M2.
    I believe you're going to need around 13-15A.
    Good luck findng a power brick with that output.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    ...... 13 to 15A sounds like alot. I'll research this more, but I have my M2-ATX hooked up to a laboratory DC poer supply, and it maxes out at 4 amps. Haven't even had it get to 3.5A @13.5 VDC yet. Of course I'm running a D945GCLF with only 1 PCI video card, and only 6 USB devices...... low W for healthy car batts

    Any cheap 12vdc/4A (depending on your rig)power supply "should" work.........

    That's the same board I'm setting up.
    I just need to run the ITX, Hard Drive and 2 usb devices when running off the brick.
    I just hate to buy 2 PS's if I could use 1 Ps with a brick.

    I will let you guys know what happens tomorrow! I Just bought the D945GCLF and m2-atx with a voompc-2 case. I bought everything from mini-box.com as well as an 8.5a power brick.

    Everything should be delivered tomorrow, I should have everything setup by tomorrow night.

    I am. My Morex 3777 came with a power brick and I'm using that to run my M2-ATX-HV/Little Falls combo. If you load the PS to the full 160-watt rating at 12 volts, you'll draw a little over 13 amps. But few applications will do that, and if they did, the PS would not be big enough--a continuous draw that high would stress that PS excessively.

    My box also has a 2.5" HDD, an IDE compact flash adapter, and a slim CD drive, that may possibly come on together at the same time once in a while. I suspect it's running at maybe 40 watts except for the occasional brief peak. When I add the monitor, it will be 50 watts. The brick that came with the 3777 is rated at 80 watts.

    I'm also leaving the coaxial plug in place, and will protect it with a diode to prevent reverse current, and will provide battery connections using a power cord with Anderson Powerpoles. That way, I can plug in the brick before unplugging the batteries to keep from having to shut the box down.

    Rick,
    I'd like to see how you wire your setup.
    I need power both ways.
    Thanks for the tip on the Anderson plugs
