You will need to get yourself a DC power supply for your vehicle.

This completely replaces the PC supply.

If you were hoping to use a standard 400w or 600w inverter, no dice. Well unless you pump out some serious money on a 'TRUE SINE WAVE' inverter. not "modified" or other such 'marketing worded' stuff.

here is a 300w car DC supply.. under $100us:

Also look into the pre-made CarPuter set ups. they have some nice stuff, for cheap, that is built to stand the rigors of automobile life. Bumps and bangs, crazy voltage changes and spikes, and temperature. Gets to +130deg F in a car on a hot day.

$251 with Powersupply.

For a carputer, those new ATOM boards will be very sufficient, and they have power supplies (DC to DC) available to directly power off of a car battery....

I have a Shuttle SD30G2 in my truck and I ended up having to use a 700Watt inverter to power it..... I am looking into replacing it with an ATOM board and their new DC to DC power supply.
