    Issues with Power Supply and Wattage being Drawn

    Well guys, after being ignorant and thinking i had it under control on such a little time i've noticed i messed up. I bought a 200w Snap-On Miniature 12v DC Power Supply for $59.99 which now i see its a piece of **** but its already done. I was woundering if anyone know around how many watts would a carpc drop. If it matters on your components which i know it does, ill list them bellow and could someone be so kind to calcute the wattege therefore i know which power supply to get, i was thinking on the Opus 150 but then i read on a different thread that a carpc draws about 160watts??

    -8" Touch Screen Monitor
    -VIA EPIA 800 Mini-ITX Motherboard
    -SD-C2402 Laptop DVD-Rom Drive Sony Vaio PCG-FXA32
    -Slim Type CDROM/DVDROM/CDRW Adapter
    -Notebook HD to IDE Converter 2.5" to 3.5"
    -Laptop HD dont know what size yet
    -Lets say 512ram

    Or to make your life easier which power supply should i get to power my components?

    Or can i do anything to the 200w Snap-On Miniature 12v DC Power Supply to power safely my carputer?

    What would be ideal for my setup the Opus 150 or the M2-ATX 160W Intelligent DC-DC PSU??
    Please Note: I will start the carputer manually after the car has been turned on.
    Sorry if im asking stupid questions, i've read quite a bit and i might have missed something but i'd be awesome if someone with open knowledge could help a newbie.

    Greatly Apreciate your help in advance

    That PW200M should work fine with your setup, but you need regulated 12v power. There are power supplies that will give you the clean 12v you need to use the PW200M.

    Here's one by Carnetix that will do what you need: http://www.mp3car.com/store/product_...products_id=60
    Have you looked in the FAQ yet?
    How about the Wiki?

    DarquePervert,

    I'm buying the "M2-ATX 160W Intelligent DC-DC PSU" for my setup. Are you saying that I also need a power regulator with this unit or is it only the PW200M that also requires a regulator up front?

    All the PW-series PSUs need a regulator for 12v.
    The M-series, Opus units and DSATX have built-in regulators.
