I have a Corsair HX650 (the old one so its only 80+Bronze). It has 4 PCIe 6+2pin power connectors (2 are being used). I was planning to SLI in the next few months when GTX 700 comes out and the 660 Ti will drop its price... Can i run SLI using that power supply? Will it be sufficient?

I am not overclocking.

My system-
Intel 3770
Asus P8Z77 V Pro
Corsair 500R
Corsair HX650
Seagate 1TB HDD
8GB Corsair Vengeance
DVD Writer
Cooler Master Hyper 212 EVO

with a single GTX660ti, total system power while gaming won't break 320w. with two cards you will peak around 470w

a quality 650w PSU like the HX650 will do the job

PU: Intel Core i7-3960X @ 4.3GHz
Motherboard: EVGA X79 SLI
Chipset Drivers: Intel 9.​2.​3.​1022
Hard Disk: Samsung 470 (256GB)
Memory: G.Skill Ripjaws DDR3-1867 4 x 4GB (8-10-9-26)
