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?

Aren't the 8 pins actually 6+2 pins ? Just leave the last 2 dangling if so.

well not my my case, but the psu came with an 8pin to 6pin which is currently in use by my 660ti. I need more connectors since I am adding a SECOND 660ti

What PSU do you have?

Most decent 750w have at least 4 PCIE connections.

I know that, I just want to know if there are any issues with using 2 adapters to run a gpu. Will 2 molex connectors be able to provide enough power without melting?

Yes it should be able to power it thru molex.
