    Question How many amps needed to power carputer?

    I have stored my car for the winter so I have my carputer back at my place. I want to be able to hook up the carputer inside so I can set everything up the way I like it for the spring.

    I tried connecting my opus 90w to a power inverter which gave out 12v and 2.0 amps. Obviously that wasn't enough amps. How many amps would I need from an inverter for this to work? Or, how do you guys connect your carputer outsde of your car?

    I have:
    m10000
    40gb laptop drive
    512mb ram
    opus 90w
    audigy 2 zs (on a riser card)

    Thanks,
    Joe

    Get a ac/dc PSU and jumpstart it and plug it into a 12v line.

    You need to find a 13.8v power supply that gives at least 5-7 amps continuous from an electrinics shop.

    Thats what I use indoors, aand I find my setup draws about 5 amps to start and then settles down at 3-4 amps depending on what its doing..

    90/12V = 7.5Amps. So I would get a a powersupply that supplies anywhere between 12-14V to the opus at 10 amps. Ofcourse, thats assuming your maxing out the Opus.

    Why not just spend $25 and buy a regular power supply?

    I found a power supply that was for an old pair of my multimedia speakers. It has an output of 12vac and 3000mA. I'm not familiar with mA. Will this work or would it be too much/too little power? If it the right amount of power, I would just cut off the end and splice it into the opus 90w.
