would it be possible to run this setup on my Corsair 650w PSU? im thinking of getting this in the near future, just wanna make sure my psu is up to scratch. Also running q6600 @ 3ghz (proberly up it to 3.6ghz down the line) 1 500gb sata HD (proberly add two more in the future) 1 x DVD-RW and 4GB RAM. Thnx 
ps. would running this on my P7N 750i hinder sli performance? i think it runs it at x16/x8
id also add two molex to 6pin one on each card as the corsair 650w only has two 6pins. thnx again in advance.
