Card? You mean the 770? Yes. Both the PCI-E power connectors from the PSU are plugged in, and the fans are running on the ACX cooler the 770 comes with. The SSD is plugged in to the MB via a SATA cable and to the PSU via the power cable that fits the plug (lol). I didn't forget to put the RAM in either
Edit: The motherboard has a long connector from the PSU plugged into it, with 2 rows of pins. As far as I know, that is the only MB power connector.
