I am already running Sapphire 6870 Toxic a factory OC card with my overclock at just over 1GHz with 9% over stock voltage.
This PSU has 2 8-Pin PCIe connectors [6+2] and my current GPU needs 2 6-pin to run : (
My oc Gpu is performing better then i expected; frame rates are fantastic with the new Crysis 2 hardcore gpu settings over 80 fps at 1080p but i'm not so sure my psu can handle a real sandy bridge OC, please Help : (
P.S. All the sata Power ports are busy with my RAID 5 config + 4 fans + 2 optical drive Blu-Ray n DVD RW
