I have a 400w inverter in my car right now. Is there a problem with buying a regular computer PSU and plugging it into my inverter? Then running everything as you normaly would? I don't need to computer to come on everytime I start my car...I still drive to school 5 days out of the week which takes me 2 mins max.

I would obviously need to hook up a shutdown controller some how but that shouldn't be too big of a deal. There's a thread around here somewhere that says how to hook up a shutdown controller with a inverter,(help finding it?). The motherboard I'm getting has the resume on power loss feature so start up isnt a problem. Thanks for answering my questions and providing any insight you have.

P.S. I was thinking about this PSU... HERE ...Maybe I dont need 450w PSU...Would it pull too much off my inverter? Should I use like a 300 or 350w PSU instead?
