I need to bench-test my M3 PSU before going through the tedious work of installing it in my car...help!!! I have a Via M10000 mobo, and all attempts at a DC-DC solution have failed to power this thing. Just got a brand new M3...same thing. Only the standard AC-DC PSU works on this board so far. I have my whole audio/video system working like a dream except for my PC(can't find a way to power it in the car that works). Any idea why???
