I have a Dell XPS 720. I just purchased a Gigabyte GTX 960 and it has a 6 pin connector and an 8 pin connector. I have two 6 pin connectors free and a molex. The card came with a 6 pin to 2 molex, and a 8 pin to 2 molex cables. PSU has 750w, so I am not looking to upgrade unless I have to. This is the first time I've purchased a card that you had to do more than just plug it in. Thanks for the answers.
