Even more so because it's for tracer rounds.
Here ya go: http://www.mp3car.com/vbulletin/advf...iew&advfaqid=6Power - This is where I'm undecided. I'd like to go with the M2-ATX, but I've been reading the Prescott P4 I've chosen will kill it, so I'm still searching what to do here. Suggestions? I will not be running an inverter. Maybe a basic 200W DC-DC power supply with a relay to energize the circuit after the vehicle is already started? Then I don't have to worry about crank survival, correct? Not worried about sleep/hibernate either.
Yeah, you're definitely pushing it power-wise with an M2. You might look into a DSATX or Opus 320w.
That or choose a less power-hungry CPU.
