I purchased a Thermaltake W0116RU 750W PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817153038 for $80 but wanna run 2 evga geforce 260 in sli. They require 2 6 pin PCIe EACH. so 4 6 pin would be needed. PSU only comes with 2. Is there a way to make this work and if so how? I would like to keep this PSU because is was so cheap and seems like a good deal for the money but at the same time i need a capable PSU so i'll get a new one if need be. any advice?
