Since I have an enclosed Dell XPS 8930, I got the standard Radeon with the blower out the back so the case stays cooler. If you google Radeon 580 power connector you will see that it's an 8-pin connector. If your PS does not have one, you can get adapters. The 1660 GTX runs on less watts than the 580 if that is an issue.
