So i unboxed my motherboard and right after i unboxed my Corsair 350D. When i touched the box i got zapped (I didn't have my motherboard in my hand). Do guys think it's dead? My CPU will first arrive on monday. This is my first pc build.
No it will be fine ☺
You did not discharge your self on the motherboard, but on the case.
As mistery said, you're good to go. Unless the shock happens directly onto the hardware device (i.e. directl on the motherboard) it will not damage your components.
I don't usually wear an ESD device since I know how to maintain a proper ground (I made that sound hard, all you do is constantly touch a metal part of your chassis) but I like to during unboxing of components.
