    J9 and J8 dead

    Hi! As many others, I wasn't aware that the J8 connector had polarity. Now both switches are dead and the U5 component is fried. The component part is NC7SZ384P5X if anyone was wondering.

    Other than that, the PSU works normally, the only problem is that i have to start it and turn it off manually.

    Is anyone aware of any alternative way of auto startup/shutdown?

    Welcome to the forum! Did you end up replacing the component? Looks like it would be easy and only .75ea, shipping will be the problem. Good luck SNO

    Unfortunately no, i still didn't order the component, and don't know how will I manage to solder it, as it is only 1.25mm wide. Allot of the problems with the m2-atx on the forum are related to that component. (pc starting and shutting down after 5 seconds because the pins are permanently shorted)

    The other problem is, even if I manage to solder it, how can I find the correct polarity? That's why I'm after a different solution Tnx!

    I have ordered 30 pieces of NC7SZ384P5X from aliexpress They will hopefully arrive in about 60 days! In the meantime I have managed to make the pc start automatically when I switch the ignition. In BIOS - Restore on AC/Power Loss I set it to Power on. Now I just have to find a way to shutdown the pc when I pull out the key. Found out a way to do it with the com cable and pin 8, bud didn't manage to make it work
