MotherBoard with 8-Pin and 6-pin CPU power

My Motherboard has a 8-pin power and a 6-pin for a gfx card., do i need the 6-pin connector or just the 8-pin, i will be using a r9 270x by sapphire. the board is the MSI 990FXA-GD65 (http://www.scan.co.uk/products/msi-990fxa-gd65-amd-990fx-s-am3plus-ddr3-sata-iii-6gb-s-raid-sata-pcie-20-%28x16%29-atx)(http://uk.msi.com/product/mb/990FXAGD65.html#hero-overview)

Thanks

Your board only has an 8 pin CPU power... where can you see a 6 pin?

(6 pin ones are used for GPU power)

Link doesn't work, but afaik there isn't such a thing as a 6 pin CPU power connector. I assume it's a additional PCI-E Power Connector that you should use if you plug in many PCI-Cards.

Now it makes more sense :) Yes you will have to plug in the 6 pin to the GPU as well as 8 pin for the CPU as the GPU can't get enough power through the PCIe slot

But that is only true if you put like 3 VGAs in it. Normally the 24-pin delivers enough power to the board to feed to the GPUs, but if you run a three way SLI or something it would have to deliver 3 times the 75W per slot. Therefore you should use the additional PCI-E connector.

The six pin socket on the motherboard is for if you are putting more than 2 graphics cards in the system

You all seem to have misread. Apart from @Hyrikan

 

With a single 270X, you don't need to worry about the 6 pin connector on the board, you'd only need that for something like 3x 290s.

Funny thing about this board is: It only has two VGA slots, so I really don't get why MSI put a additional connector there anyway.

Well you could put 6 graphics card with PCI-e risers...
