Hi, can i use molex splitter to be paired with ( molex to 6pin PCI adapter) to power up my second GPU, as a adapter required 2 molex.I already use the 6pin PCI by the PSU to power up my first GPU.My PSU only have 3 molex and i need 4 molex to be paired with 2 adapter to convert into 2 x 6pin PCI.My GPU need 2 x 6pin PCI.Will the molex splitter provide enough power similar to 2 molex?Will it damage my GPU?

Its likely : PSU>molex>molex splitter>molex to 6pin PCI adapter>GPU

My PC Spec :
Intel Core i5 2500k
Asus P8P67 PRO Rev 3.1
G.Skill 8GB (2GBx4)
2 X Sapphire HD 7870 XT
FSP Raider 650 Watt PSU 80+ Silver
Seagate Barracuda 500GB

Please Help!!!

Hmm i see the new problem, only one molex cable. Try to find sata to 6pin pci-e like: http://www.amazon.com/Monoprice-108494-8-Inch-15-Pin-Express/dp/B009GUP6O0/ref=sr_1_1?ie=UTF8&qid=1392399769&sr=8-1&keywords=sata+to+6pin
Video1: 6 pin + molex to 6pin
Video2: 6pin + sata to six pin
I think that this combination has the most chances to work.
You can try only with molex but chances are very low.
And you do not need molex splitter, just attach only one molex in the converter cable - adding a splitter will not increase the available watts anyway - they all "come" through the same wire.
Hope this helps.

Better split the power so that each card has 1x6 pin PCI and 1x molex adapter cable. 1 molex cable for 1 card, Different molex cable for the second one.
But I read that 7870 XT uses almost the same power as 7950, and 750W is recommended for 7950 xfired.
It is 50/50 this to work. Be prepared for a PSU upgrade.
