ocz powerstream 520 sli

ok my new ocz power supply will be here tomorrow, i have a quick questiong. it says it has 2 vga/hdd connectors that are supposed to be optimized for more stable voltage. now right now i am running 1 7800gt but am getting a 2nd next week. should i use those 2 connectors for the 1 7800 now or just use the one 6 pin pci-e connector. the powerstream i ordered has the 2 pci-e connectors. how should i set it up. i have 2 hdd's

The PCI-E cables are shielded just like VGA/HDD molex cables. Just use the shielded molexes for your harddrives then.
