No argument -- seems very reasonable.
My thought is this.
CrossFireX and SLI use 2, 3, or 4 cards. For each of those GPU cards (up to 4 on a big motherboard), the limit is 75W off the PCIE bus (cards other than GPU have different limits).
If a person is only using one GPU, how bad is it to use say 100 PCIe watts on a bus that supports 2, 3, or 4 x 75 (150, 225, or 300W)? Likewise, if one is using 2 GPU in CrossFireX, how bad is it if those two cards use the power of 3 cards.
Just wondering if this concept is why no-one has reported problems using one of the "over powered" PCIe Bus powered GPUs. That is, there is actually "room to spare" -- particularly if a person only has one or two GPUs plugged into the PCIe Bus.
