Should tell you in your graphics cards user manual, To me it looks like a 2 pin fan header, but im not sure to be honest.

BTW your question is very hard to understand.

Indeed... we need more info..
Can u show us the pic or the link of your card?

See the white connector, I think thats what hes talking about.

Wow, i never know it before... (thx omg)  
Not sure what to do with that connector...
Yeah, it should be on the manual, just check it...

SPDIF connector (?)
If so, it's used to run digital audio from your audio card to your graphics card and then pass it through, say, a HDMI cable to your HDMI compatable monitor with speakers or TV with speakers.
