So I'm getting the GTX 670 MSI Power edition which requires x2 6 Pin PCI-e cables to be connected to it to power it. My power supply only has 1 PCI-e 6pin cable, so all I want to know if I get this

http://www.amazon.co.uk/Startech-com-Express-Power-Splitter-Cable/dp/B004NNTVT6/ref=sr_1_1?ie=UTF8&qid=1370292866&sr=8-1&keywords=pci+6pin+splitter

and put the 6pin cable I have now into it so then I have 2 6pin PCI-e cables will it work?

My power supply can handle the card ect so I know it will work with the card.

Yup, perfect solution, provided your card has enough Amps on the 12V line feeding that single 6-pin of yours.

Cable splitters are a perfectly legit way to deal with newer hardware requirements. Best of luck.

Yes that would work but the question is will the PSU you have be good enough to run the card. What make/model PSU do you have because if it only has one PCI-E power cable you may not have enough amps/watts to really power that GTX 670 at full load.

I have got the same problem and my PSU is a Coolermaster rs-500-pcar-i3

So can I do that cable splitting as outlined above with that PSU and my GTX670?

It should be fine. But the PSU is a bit under the advertised 500W. On the PSU, it says that the +3.3V, +5V, +12V1, and +12V2 combined cannot exceed 431.5W. So if I add that to the -12V and +5VSB, it's only a 450W PSU. But the combined +12V rails provide 30A current rating so that's more than sufficient since the GPU requires 15A. But that's just the GPU. You have to account for all other parts of your build because the PSU powers them all, not just the GPU.
