How do I power the HD 7950 with 4x4 pin?

[Mikoloco]

Like, I'm thinking about getting a VTX3d HD 7950 but I have 2 4x4 pin connector and I'm not sure of what I'm supposed to do to make it work.
Help appreciated.
My PSU is an LC Power 6600

you mean 4+4 pin? you want to plug in the 6 pin or 8 pin pcie connectors 4+4 pin is for the CPU power

But I have one of the 4x4 pin connected to my current gtx 650 TI

From the specs I think that PSU has just one 6+2 pin connector (you just leave the 2 pin off). You need two 6-pinners for that GPU. So you will need to buy a molex to 6 pin adapter (like one of these http://www.ebay.com/itm/New-Dual-4-Pin-Molex-To-6-Pin-PCI-Express-Adapter-Cable-/140393887955)

Any of these will do?
Is there any other type of requirement??
Thank you by the way

It may work like this but some PSUs don't supply enough juice to the standard Molex cables so you may see issues especially if the GPU is under full load. Most newer PSUs come with dedicated pins for the GPU that supply enough power when it needs it.

Many GPU's will have the amperage they deliver to each rail. Those molex adapters work fine in my experience (used them for many years on an older 450W PSU right up to an HD7950).
