Crosshair V Formula Z: 3x XFX 290X Crossfire with Missing GPU
I have 3x XFX 290X and one of my cards does not appear in the Device Manager or the Bios PCIe info.
I have a Rosewill 1600W PSU and have connected all of the power connectors but this one near the board.
The user guide/manual does not specify that it has to be connected for Trifire. I only found one post that references the connector.
Would this prevent the card from appearing in the bios?

FYI: All 3 cards worked fine individually on a Sabretooth Rev 1.0 990FX as I am upgrading from a 2x configuration.
