I would strongly recommend using the supplemental power if using 2 GPUs, and advise anyone using 3 or more to use it. The 6pin connector prevents the PCIE lane from over-drawing from the CPU or 24 pin connector, and can prevent damage to your motherboard. As bdary mentioned, this first became apparent in the X58 series, and we've included the supplemental power ever since.
