hello, i just got my EVGA 650 GS 80+ , i unboxing , checked everything was on its place, but when i flip the psu it sounded like if something inside was loose,like a tiny screw or something, is it normal?

rma?
is not that i threw a screw by accident, i didnt even try to put it into my pc case,i havent turned it on, i just got the psu out frm the plastic bag, fliped it, and it made the sound of a screw loose inside, i dont wanna turn it on, what if i loose my pc,  im about to ensamble  my first gaming pc it, 5 month savings...

no i was wondering what if i use that test thing and something goes wrong :p, is still a valid warranty?

i checked and yes, its a screw, here are some pics, if i  remove the screw do you recommend to use it anyways? its is not supossed to be holding something?
