[m1337]

ok so i just got the card and it has 6 PIN power to 2 molex conectors

do i still have to use them if my PSU already have PSI E connector ?
or they are just incase my psu dont have PSI E conector

and i also got this little metal thingy looks like a guitar pick what is the purpose of it ?

If your PSU has the 6pin built in to the wiring then you don't need to use the one that comes with the GPU as the the little pick shaped thing not to side unless it has the company's name printed on it if that's the case its a case badge to say you own a "evga or what ever brand GPU"
