We recommend that you provide sufficient power when running CrossFireX™ or SLI™ mode.

Connect a chassis fan to the motherboard connector labeled CHA_FAN1-4 when using multiple graphics cards for better thermal environment.

We recommend you connect an EATX 12V_1 cable when running CrossFireX and

SLI.
