Something really interesting happened to me during these days while repairing a PC that came to my place. It was an M2N-E motherboard, AM2+ which i saved from a burnt PSU (not literally, but the fuse was burnt because the owner connected it with the wrong AC volt input line; the PSU was repaired later), but when i tried it with a Coolermaster RS-700-PCAA-E3 psu i had random shutdowns for almost a day. On next day after searching for burnt components on the board and not finding anything, the system just turned on and it worked with no failures for almost 20 hs. The next day i had the same issue again (constant random shutdowns), which made me test the board again, but i didn't want to take all the capacitors out trying to find a little failure; so i decided to test a lower 300W psu and it worked. It boot up with no problem so it made me think that the PSU could be the problem; but after testing it with my motherboards (all of them better and newer than the M2N-E) i found that the PSU was working fine, the voltage reading were fine, the ripple was not high, and no sign of instability. I had an issue with this psu one month ago testing an old 754 unit with instant shutdown and no video showing on screen, but i really didn't care that much, because those old units could have problems, even when those worked with an old 100W PSU, but now i don't know what to think about it.
Somebody have any idea why did that happen? I think about many possibilities, but i'm sure for none of them.
