    How many Watt I need?

    Hi @ all.
    I have a little problem..I will make a power supply DC-DC for my car.
    This PS must keep active a pc like that.
    - P1@133 + fan
    - 1 Hd
    - 1 Sound Card
    - 1 Video Card
    - 1 Net Card
    - maybe a CdRom...

    How much Watt consume that computer?
    I found a PS (mk2.6) that provides 60W..It's enought?
    Otherwise I found another PS (mk3.5) but it's more difficult to make than mk2.6..
    Is there possible have other link?
    Thanks at all.

    Ps:- Sorry for my bad bad English..

    To calculate more precisely, search using terms "power calculators". You should find links to power calculators that will allow you to input your system and estimate the wattage.

    Any response?
    Is any simple schematic for a DC-DC over 70W?
    I see Mk3.5 it's a bit complex, but I didn't found how place component on it...

    I search, but all post I found, are too old and the link to schematics doesn't work.
    An example? w*w.sproggy.com
    Isn't possible have some link to some Dc-Dc converter a bit simple to build?
    Thanks and sorry for my bad English...Have patience..
