Hello all,
I am buying parts to build for my gaming computer, my knowledge is pretty limited so was hoping someone could help me out.

Regarding the HD 5970 video card and power supply.

I've read that the card req's 1x 6-pin 75w and 1x 8-pin 150w, however can 2x6+2pins run the card without any problems?

That PSU will run it with ease.

an 8 pin is essentially a 6+2 pin, every PSU I have seen has used that format.

Regarding this thread and the responses from "Notty22":
http://www.tomshardware.com/forum/300306-33-sapphire-59...

To summarize, in that thread the user had this PSU:
http://www.newegg.com/Product/ImageGallery.aspx?CurImag...

And was finding that his system was shutting down due to heating problems from the psu.

The PSU he used has 4 12v+ rails with 20A each, and notty said to use either PCI-E cords 1+3 or 2+4 to provide supplement amps. Notty said not to use pci-e cords 1+2 as that would do the opposite.

Now regarding the PSU that I posted above, I see on the back of the PSU, that it only has 2x 12V+ and - rails, one w/ 60a and one with .08a. They are alternating amps, but since they are alternate amps would it still apply to what notty said about not using "1+2" of the pci-e cords? I dont think I could use the other pci-e cords of the corsair power supply I listed in my OP as those are 3.3v rails and lower.

Of course I may be completely wrong in my conclusions from that thread and this one , as I literally have no knowledge when it comes to PSU's and graphic cards, I just wanted to make sure that the PSU will work, and how I should be hooking up the PCI-E cords as there are only two 12v rails on the PSU I suggested.

thanks again

Don't worry about the -12v rail. Any Corsair PSU uses a single rail for maximum stability and reliability. Hence, their higher price tag.
