PCI Power Confusion

[Fergy007]

I have recently been contemplating getting another Msi 7950 to xfire with my current one. I have a CM 700W silent pro PSU, i'm sure the 700w will be enough.

 

My PSU has two PCI power cables which have a 6+2 pin and a 6 pin plug on each, daisy chained.

 

Since a 6+2 / 8 pin cable can give 150w of power then surly I can use both 6 pin plugs on the daisy chain which give 75w each for one GPU???

 

This would allow me to power both GPU's with just the PCI power cables.

 

Can anyone tell me if my theory's are correct?

 

Thanks

assuming the other cards using 2 6 pins which i believe 7950 does, It'll work.

Yes.

unless you find yourself with 2 7950 that require 2 8pin cables you'll be fine =D.

 

Check the manufacturer's webpage and see how many 6pin connectors do they use.
