Well I figured that I would go the simple and cheap route buy buying an inverter. (despite what I have read)
I purchased a brand new whistler 400W continuous 800W peak inverter from walmart.com for $30. The inverter works fine and powers everything EXCEPT my PC. The PC will not go passed the Compaq screen. (I have an IPAQ shuttle P3 1 GHz)

So apparently my PC does not like the modified sign wave. I know the inverter is producing enough power because the overload buzzer does not turn on and I have it wired directly to the battery with 8 gauge wire. So unless there is something I am unaware of it has to be the unstable AC power. The PC boots just fine when plugged into a normal outlet. The power supply on the PC requires 3 Amps (300 watts) so 400 should be plenty.

I did not buy a dc-dc power supply because
1: it was more expensive
2: my PC needs a special 10 pin connector for the motherboard
3: I was too lazy to make an adapter for the mother board.

Now it seems that this is what I have to do....


Any suggestions on how to make the inverter work and to stop that horrible whinning noise it makes when the computer is plugged into the speakers (I have a ground loop isolator, doesn't help much)?

Can you get a DC-DC power adapter for around $30?

Any suggestions welcome?
