Are you trying to crossfire with another 5850, 5870 or 5970?

If you would crossfire two 5850s then you could but with molex connectors. But for a 5970 your psu doesnt have enough power. I am basing this off the wattage and you only have 50amp total off you two 12volt rails.

"650 Watt or greater power supply one 75W 6-pin and one 150W 8-pin PCI Express power connectors recommended (850 Watt with two 75W 6-pin and two 150W 8-pin connectors for ATI CrossFireX technology in dual mode)" - New egg (5970)

Not necessarily bad, just not as power efficient as PCI express connectors. That's why they make PCIe connectors, or else they would just give you the option to put molex connectors on everything.
