Question about Gigabyte GTX 750 TI

[Mrex19985]

Hello!
I have bought a new Gigabyte GTX 750 TI,My PSU doesn't have a 6 pin power cable, So i will use the 6 pin power adapter that came with the GPU,
But the power adapter has a duel power connectors.

My question is should i connect the tow cables or one is OK?

Sorry i know my question is stupid, But i like to be sure about everything!

Sorry for my bad English! ^_^

You need to connect both; one alone won't supply enough power to your graphics card.
