the inverter you are talking about takes 12v dc, makes it into 230v ac(or 110), and the psu converts it into 12,5,3 and all the voltages a pc uses.
a DC-DC supply takes the 12vdc and converts direcly.

What is it and how does it work?
Ok so maybe that was too general. I do understand that you can power the computer thru a normal ATX psu and an inverter. This was the route I was planning on going but I hear sooo much of the DC-DC action that I want to get in on it.
The only real question is how do you implement this into your system? Do I just wire the accessory line directly into the PSU? So it's getting direct power from the car and not thru the inverter.
Also the wattage always seems so low. I see a connector for the mobo and perhaps one other power connector for just one other device (the hard drive). Why only one connector? what if you need to power a DVD/CD-ROM drive? Or you want to provide 5V or 12V to your LCD/Controller/etc...how do you do this when the PSU only provides one power connector?
My system will be a Shuttle FV25 with a Cel P3
20GB laptop drive
Sharp 10.4" LCD with Datalux controller
How do I power the DVD drive and the LCD with the DC-DC? Even if the DC-DC provided 2 power connectors that wouldn't be enough to assist on powering the controller for the LCD.
Let me know what my best option would be!
