Solved 660ti with 2 6pin adaptors from psu Tags: Power Supplies Graphics Cards Components Last response: August 15, 2013 8:36 AM in Components Share oczdude8 a b ) Power supply a b U Graphics card August 15, 2013 7:26:53 AM Hi, I want to know if anyone has had any luck with using a 2 molex to 6 pin adapter to run a power hungry gpu (660ti in my case) I have a good 750W psu but it only has 1 6pin and 1 8pin which is not enough, since I want to add an extra 660ti in sli, (strangely enough, it is sli certified....) Would it be okay to use 2x molex to 6 pin adapters like this:http://www.amazon.ca/HDE-Pci-Express-Pin-Molex/dp/B004V... From what I know, a 6 pin connector has 3 12v lines an 2 grounds, while using a 2 molex adapter will only yield 2 12v lines an 4 grounds to my gpu. Would this be okay? I have about 4 molex connectors free from my psu, so each 6pin would get 2 dedicated molex connections. Anyone know what gauge the cables usually are and what they are rated for?
