Okay, first post here, a little background on what I'm doing:
I'm doing my first full PC build. I've done a little tinkering in the past with upgrading components here and there, but not a ground-up build. My son had a Radeon XFX HD 6950 graphics card laying around that he wasn't using, so I incorporated it into my build.

My power supply is a Corsair CX600 modular. Okay, here's where the fun starts. My PSU has three 6-pin PCI-E connections and one 8-pin PCI-E. I have two free 6-pin receptacles open and one 8-pin. The graphics card requires two 6+2 PCI-E connectors. I can find 8-pin PCI-E to 6+2 PCI -E (F-to-F) cables, no problem. I cannot, however, find a cable that has a 6-pin PCI-E to a 6+2 PCI (female-female). I have scoured google to no avail.

My PSU came with a splitter cable (8-pin PCI-E to 2 @ 6+2 PCI-E), but it sounds as if this is not an acceptable way to hook it up.

I'm hoping someone will respond here with a simple solution and make me look like a dummy.

Thanks!!

The card uses 2 connectors and if the PSU provides two cables to connect it fine if not it will work fine if both connectors come on the same cable since it is a single +12 volt rail PSU.

The PSU only supplied the 8-pin PCI-E to (2) 6+2 PCI-E splitter cable. I was fully prepared to use this setup, but AMD "recommends" using to individual cables rather than the splitter cable. This would require having a 6-pin PCI-E X 6+2 PCI-E (female-female) and I just can't seem to find such an animal.

If the splitter setup would work, that would be awesome. AMD says (2) separate 75W PCI-E connections. I'm just not smart enough to figure what I'd be pulling per connection through that splitter setup.

The splitter cable will work no problem since it is a single +12 volt rail PSU! The cable can easily carry the 150watts.

6pin PCIe power delivers 75watts and an 8pin 150watt as specified in the PCIe std.
