It will work, I have used one in my Offroad trailer to power lights and 12V fans, works great. I used a 500 Watt for my applacation because it has more 12V outputs which I needed.

How much power do the standard AC-DC power supplies in the computers require?

IIRC, there are many who have done similar things but on other forums. Guys, wasn't there a website like MP3.com or something similar that had a forum where you could discuss this in more detail with folks who focus on it? I recall they were doing things like using custom OS interfaces & modified touchscreens in custom cases/physical installs to make their car-puter easier to use.

Alternatively you may be able to get by with using a inexpensive 12vDC to 110vAC power converter. Yes I know it's pretty inefficient going from 12v DC to 110v AC back down to 5/3v DC but it may ultimately be simpler and easier to support versus using a modified power supply that if it goes bad isn't necessarily as simple to fix/replace.

I went through a similar exercise with my netbook. I spend a few days looking for a 12vDC to 19.5vDC converter with sufficient current ratings to support my netbook. Ended up being more expensive to buy than a $50 12vDC to 110vAC power converter that fits nicely under my passenger seat and can easily be replaced should it fail (one already has after ~ a year of use).

I don't mean to discourage you but do want to offer other ways to make it happen in case the modified power supply idea falls through.

Either way, I look forward to seeing the results.

Would you be a dear and do a write-up? <img src="/forums/images/graemlins/cheers.gif" alt="" />

Thanks

Dear? WTH is that?
