PCI-e connector and graphics card

[blackbke]

Hi,

I have a Coolermaster Silent Pro Gold 800w PSU. It has 3 seperate cables with each a PCI-e 6-pin and PCI-e 6+2 pin. Now I'm a bit confused, can I use one cable to connect my AMD 7950 card (two 6-pin connections needed), or do I need to use 2 seperate cables?

I would say I can use only 1 cable, but on the instruction card for the graphics card it's explicitly stated 2 seperate cables should be used instead of 1 cable with 2 split PCI-e connectors. But then I also read that it's ok to use a split PCI-e cable if your PSU has a single rail 12v with enough amperage, which this Coolermaster definitely has.

Someone kill my confusion. Thank you

You're correct.

I think they have to take into account a 'worst case scenario' in which that might be true which could happen with a low end, budget PSU that has multiple current limited 12V rails.
