Max power consumption varies depending on which core you have. Intel lists "typical power consumption", unlike AMD which lists max. Still, you have to read between the lines for certain processors.
Here are the 2 Intels:
Intel Pentium 4 A 2400 MHz Prescott (89 Watts)
Intel Pentium 4 C 2400 MHz Northwood (66.2 Watts)
So you have to increase the wattage a little to get the max. Figure 100w for the Prescott and 75-80w for the Northwood. Now under normal CarPC usage your not going to be pushing the CPU very hard so it will be running cooler.
The new 90nm AMD Sempron, for comparison, maxes out at about 30w. This is the 3000+ model.
I know the AMD's pull their CPU voltage from the 12v rail, but I think the Intels get their voltage from the 5v rail.
