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?
