help identifying SMD component marked N1

Hi there,

I am trying to repair an SMPS (PS3) an I have a component which reads differently when compared to a working PSU.

It's only labelled N1 and it says Q304 on the PCB - so maybe a transistor?

Does the N1 tell me anything about the specific item?

Thanks!
