Yeah, but that doesn't test your PSU, only the PC hardware.

Hmmm, DP, I'm not sure I understand how you mean it "doesn't test your psu".

12v battery to the dsatx and she fires up and shuts down with a connection simulating acc. Seems that would be a better test of the DC-DC psu as that's what it'll be running off in the car.

But yes, I use the atx power supply when I want to do extended testing on the os or a complete reload in the house. Just seems more conveineint to me.

I guess I just don't see the point of hacking up an atx supply to get what you would from a battery which would be more realistic of a test.

Different strokes I 'spose..............

Maybe I'm missing something here?

well i tried this out today and it fired up perfecty fine for the first time in my build.

i used a battery charger i have in my garage.

this is the one: here

NEG and POS off my m2-atx to the proper clamps on to the battery charger. On the ACC line i wired in a switch and then connected it to the POS on the charger also.

i tried it on the 5amp setting first but it wouldnt start up. it would try but then turn off. i switched it to the 15amp and it fired up fine. i started/shutdown using the switch 3 times with no problem.

Connecting the ATX power supply right to the motherboard of your carPC doesn't test your DC-DC PSU.
I should have been more clear.


Not everyone has a battery charger at their disposal, but yours is a good idea.
You can also use a spare car battery. Again, not everyone has a spare car battery.
Some have 12v power supplies that put out enough amperage to power their vehicle computer. Again, it's something that not everyone has.
Granted, not everyone has a spare ATX PSU lying around either...
Most PC geeks (like myself and many others on this forum) tend to have PC parts about, including a PSU.

Understand that this FAQ was written up as a CHEAP way to power your PC inside. It's also a cheap way to do it using stuff that some people may already have.

Using the Old ATX supply laying around, and following Darqu and Vlads posts's, I did this in all of 3 minutes, and it workded great! Thanks...

This is an amazing "how to" took me about 10 mins to set up (and that included finding wires and connectors in the toolbox!)

Thanks guys.

I have a radio shack AC to DC converter. Will that work It only has a - and + Termnial. Can provide a constant 25amps if needed and provides 13.8v.
Will that work. Its been to run car amps in my home before?

Rob Withey

yes.
