Is there a power connector that needs plugging into the LB?

Is there a power connector that needs plugging into the LB?
Or does all the power come from the PCIe bus.

Mac Pro early 2008 3,1.

Thanks ... Ken

    Yes. The 5770 needs one extra power cable (included with the upgrade kit) and the 5870 requires two (both included with the kit).

  • Yes, the ATI Radeon HD5870 requires additional power. You will need to plug 2 6-pin power connector cables from the card to the Mac Pro logic board. The Radeon HD5770 card only requires 1 6-pin power connection cable. Apple includes the necessary cables in the upgrade kit.
