M-ITX P4 3.06 Ghz and PSU troubles...
I'v tried searching, but couldn't find an answer to this problem.
Here's the setup we're using:
Car = 2005 Mustang GT
Minit-ITX P4 845GVD (link
P4 3.06Ghz s478 cpu w/HT
Low profile heatsink + fan (12v @ .15A)
1Gb PC2700 DDR
1 2.5" 60Gb hard drive
120W PSU that came with this case.
Desktop P4 400W ATX PSU.
The problem we're having is that when powered by the 400w ATX PSU in the house, everything works fine. However, when we move the PC to the car and use the PW200V (the P200M died), the lights turn on, fans spin, but doesn't POST. No beep codes or anything. We've tried everything we can think of including using one PSU to power the Motherboard and one to power the CPU (for a combined total of 320W)...but that didn't work either.
Anyone have any insight on this? The power is run straight from the battery from a 8gauge wire which feeds a 4-channel 60w amp and the PC. Would running an entirely seperate 8 (or larger for that matter) gauge wire solve anything?
