After I've installed the motherboard into the case and turned it on - It did not turn on. I tried to check all connectors and all seemed fine.
I took a PSU tester and saw that the DC to DC PSU works. Then I took a regular ATX PSU and it did work with the mini itx board. I was puzzled !
Then I connected again the DC to DC PSU to the mini itx board and it worked !
I wonder why the DC to DC PSU didn't worked in the 1st place.The board did showed a green light (Which is a signal that it gets some kind of electricity from the PSU). This board doesn't have the cpu 4 pin psu connector on it. Is it possible that testing the DC to DC PSU with the PSU tester turned on some kind of logical switch in the PSU ? (like the 4 pin connector) ?
The system works for about 24 hours from yesterday. I turned it on and off several times and it looks ok, But I'm still puzzled....
