I am trying to install a GTX 980 FTW into a Dell XPS 8900 Special edition. The card has (1) 6-pin and (1) 8-pin female connectors. This machine has a cable leading from a 460W power supply that splits into (2) 6-pin male connectors. The kit includes two adapters: one that has (2) female 6-pin and one male 8-pin, and one that has (2) unidentified female connectors (old school IDE hard drive power connectors?) and a 6-pin male connector.
Any friendly advice on how to connect power to this card with this configuration and adapter options?
