    Default SLI / XFIRE Power Connector

    Hello,

    As the title says, does anybody knew about this SLI / XFIRE power connector? I've been reading through the manual of my ASRock Extreme 6GB and it say's

    " It is not necessary to use this connector, but please connect it with a hard disk power connector when two graphics card are plugged to this motherboard".

    which obviously applies to me, I have 2 graphics card in SLI connected to this motherboard and bit confuse of what significant improvement it may result to the performance of my PC if i were to connect hard disk power cable?

    really appreciate if somebody can enlightened me on this.


    thank you,

    Connecting an additional psu power cable to the appropriate motherboard connecter provides an additional power circuit that can often help to stabilize a multi-gpu setup. This additional power circuit will lower the electrical loads on the existing pci-e power circuits. The overall electrical load on your power supply will remain the same, and all of the pci-e power circuits should be more stable. This is most important when you are running demanding games or encoding videos, especially when you have overclocked your video cards.
