    well, the powersupply for that computer (from what i can find) is 220watts, so ur already pulling a lot, and thats for the computer itself, no screens or anything else

    so you'd either need the DSATX, or a couple of power supplies in there

    theoretically it should work, but hte power supply mobo connector looks ATX, so i dont know why you'd have to rewire?

    I'm not sue if i have to tbh. Some dells have what appear to be standard atx power supplys, but the wiring is NOT atx standard, afaik there isn't a list of models that are normal atx instead of dell atx. Only way to know is to try it i geuss. I also dont need much more than it requires. Theres not a whole lot that be done to expand it. I'm gonna add a low-profile pci video card, and thats about it. The screen and such will have thier own power supply and what not in the dash.

    It should work if you get all the wire correctly.
    And use the meter to check for all wires while the PC is on and when off as well. The only thing it wouldn't work is probably the power good signal.

    The problem with some Dell motherboards is that the power connector is not made to the ATX standard. I don't know if yours is or is not.
    For those units, a Carnetix PSU (like the P1900) is likley to meet your needs.

    If your unit connects with a "power brick", read the rating on it, and we can tell you whether it will work or not.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Mine does not use a brick, ill double check when i get home (im at work) but i believe it has a 20 or 24pin plug and the 4pin p4 connector.

    I suggest taking the safe route and determining the pinout of the Dell's PSU (and/or motherboard) and comparing it tot he pinout on a standard ATX PSU to make sure they jive.
    Dell has been known to use proprietary hardware that doesn't conform to any specification except their own.

    Yes, dell and their annoying proprietary powersupplies. Had this problem with a dimension 8100 I wanted to convert into a CarPC. My solution: found a cheap, new motherboard on ebay.

    Good luck
