More about bridges needed crossfire
  1. Best answer
    Crossfire requires one bridge (between the 2 cards); there are 2 sets of bridge connectors on AMD GPUs to allow tri-fire. Your power supply is more than adequate.
  2. Some cards require 2x connections.

    both my 5870 & friends 5830's both need 2 crossfire bridge cables in order to enable Xfire.

    if both cards have 2x CFX connectors you will need 2 cables.
  3. 2 way CF = 1 bridge

    3 way CF = 2 bridge

    4 way CF = 3 bridge

    Same goes for SLI

    Most the time, people don't have issues, but sometimes it will cause weird problems. It's best to leave it off.
