ITX DC-DC power troubles

**lessthanchris1** · 05-23-2005, 10:10 PM

Hi, while I am new to this forum, I've had my first generation car pc for a few years. It ran on a regular ATX power supply, powered by an inverter. This time around, ive opted for a small mini-itx board, with a DC-DC power supply. so here is the problem:

When i try to boot the pc from the dc-dc supply, the cpu fan turns, but nothing else. the drive and board do not boot. However when i plug this into a regular ATX supply, it works perfectly.

My hardware:
100W DC-DC power supply
200W DC-DC supply (from mini-box.com)
Western digital 40GB drive (~25 Watts consumption)
PIII-933 chip (~23 Watts consumption)
FX815ELT socket 370 board (~10? Watts)

Any ideas, suggestions, would be greatly appreciated!
Thanks!
Chris

so yea..... turns out my car cigg adapter had a fuse in it.... ".5A"

LOL, whats the quick fix? (until its hard wired, of course) DENTYNE ICE GUM WRAPPER wrapped around the fuse. provided enough current to power that sucker right up!

Thanks to all who emailed me and helped out!

Big red works better!

Edit: BTW I am almost positive you mean a 5A fuse... because that is very common, and .5A would only be like 6 watts! 5A is still only 70 watts, which isn't enough either.
