I set up my new build today and while I was connecting the mains power cables on the motherboard, I heard I shortage electric sound, I immediately pulled the plug out!
How can I know if my mobo is dead or good?
I surely have to change the psu, but can the mobo be saved?
So frustrated over this

I managed to power it on just for a second, after it was going off.

Now when I plug it I see the light on my keyboard but it doesn't power on even for a sec just the way it was doing it

I managed to get back to the point I was in the beginning. It powers on for a sec and then it goes off. If I press again the power button it loops on that. Do you think I need an alternate psu?
All fans, drives, CPU cooler power on during that sec.
Can it be that the psu is not sufficient enough for this built?
