    WTF is the Tualatin? I had never heard of these chips... oh well...

    and in what way would this setup be better than say a shuttle or other mobo, with a P4 or celeron (or even a ITX P4 board), with a slimline DVDRW drive, and a large laptop HD (or 2) should be able to power it with an opus I'd think... or a keypower...

    And also, why do you want that much stuff in the car? Like the kickass graphics, is your display going to match that graphic card quality?

    those power calculators imo are full of *****. they kept reading anywhere from 210 to 250 watts for my system, yet the OEM psu its running quite happily on is rated for 160W max.

    dont forget to add the

    GeForce FX 5700
    the two sticks of ram and so on

    it has two hard drives but when using the calculator leave out one

    I get 155watts with just the CPU, video card, and hard drive

    it calculates peak wattage thats why it seems inflated.

    1) why are you stuck on that setup? Have you considered that you wont need gigabit ethernet, motherboard might be inneficient? what will you use your ubber-graphics card for in the car?

    I'm not against high-end machines in the car like some users are, but just when it becomes an issue of "so much power I absolutely need a huga-*** inverter and water cooling system" I think you can review the machine choice maybe...

    2) do check other calculators, and the ratings for the components themselves!!! This calculator is much inflated like I said (and vchat confirmed)...

    3) check out a calculator with separate rails if you can (there is a link in one of the recent threads) as you might be surprised that all your 200 watts are on 12v, and then even the PSU you are thinking about wont work... (I'm just giving an example)


    PS: as far as I can remember all calculators I've seen calculate peak (or almost there) wattage... but the 150w rating or 90w rating or whatever isnt always peak... so you need to match these...
