Should a a 3A mini (smaller fuses than regular car ones)

I blew up the 3A fuse in my mini just a week ago : )

(came wrongly inserted on delivery -.- )

Hope this helps : )

I'm not talking about the one in back PSU, I mean the flat plastic one in my motherbaord (Motion control board?)

It says a 3 or E on it and is pink
