Antec EA650 to crossfire two 5850

I have one Asus EAH5850 DirectCU which uses a 6 pin and 8 pin power connector:

I also have an Antec EA650 psu which states that it is crossfire ready:

My question is that since i am using the only available 8 pin and 6 pin connectors for one gpu, how will i be able to crossfire a second 5850 with this psu? Do i have to use both the 8 and 6 pin for one gpu or do i simply use the 8 pin for one and the 6 pin for another? Or are there sata-to-pci adapters i can install?

Thanks for any responses :D

  1. The PSU has the power to drive the cards but you would need to use 4 of your 4pin molex and adapt them to PCIe 6 pin and 8 pin respectively. I would use the two original PCIe connectors on separate cards + one adapter for each.
