He's just stating the card's theoretical maximum...
8pin PCIe -> 12.5A @ 12V = 150W
6pin PCIe -> 6.25A @ 12V = 75W
PCIE 2.0 x16 lane -> 75W
8pin + PCIe 2.0 -> 225W max for the 9900gts
8pin + 6pin + PCIe 2.0 -> 300W max for the 9900gtx
There isn't enough data on the card to form an accurate
GeForce 9900GTX has 512-bit memory controller, 1GB GDDR3

A secondary source has told us some interesting bits about the upcoming GeForce 9900GTX, a card which will be based on the GT200 chip. We provided you with quite a lot of information last month, and the second source confirms pretty much all of it. The only real difference is that GT200 will be the heart of the GeFoce 9900 series, which was confirmed earlier. The source confirms 240 shader processors, 32 ROPS, and a 512-bit memory controller. This means that the high-end card will sport 1GB GDDR3 memory.
He also said that the card will require power from both a 6-pin and an 8-pin PCIe power connector, which is far from surprising as we're hearing that the chip has 240W TDP.
According to NH 240W TDP...
The 8800GTX had a max TDP of 177W (if I recall correctly) but in actuality consumed between 115-120W.
