    Best way to power a non-atx/itx motherboard?

    The power connector on my motherboard is very simple, consisting of +5 +12 and ground leads. Right now I have it hooked up to a regular AT power supply plugged into my wall, but I have no idea how to power this thing from my car other than with an inverter or something like that. How should I do this?

    Here's a picture:

    those voltages will be on any itx power suply... might be simplest just to get a 'mainstream' dc-dc and do some hacking.

    Oh wow, I learn new things all the time here. Neat. So what sort of DC-DC device is reccomended? I'll be powering:
    • pci 802.11b card
    • 1 60mm fan
    • lilliput 619 w/ ts (powered separately?)
    • fuji laptop hd
    • slimline cd/dvd
    • usb keyboard
    • usb "gps mouse."

    Also, do any of these fancy shutdown-controlling devices that I see around here work with a non-atx mobo?

    Edit: Would something like this work? It appears to be cheap and tiny.

    I don't have any experience with that power supply. The trouble with AT based systems is they don't have anywhere to hook up something for a shutdown command. I was just reading somewhere in here where you can use the UPS shutdown feature by inputting 5 volts into one of the serial port pins. There's also a neat little program in here somewhere to shut down the system bu shorting 2 pins on the serial port together.

    When I found this place I was up until 3am a few nights just looking at all the awesome information in here. Some of the things I found in here were absoloutely brilliant.
