While these are most likely counterfeit, a user on the XtremeSystem's forum has posted a picture of what is described as a "mechanical drawing" of two 9900 cards (GT200).

The poster of the thread on Xtreme Systems claims that the screenhots show the upcoming "D10U" products, one board codenamed P651 and the other P65x. If these pictures display an engineering drawing of the actual product, then we now know that both the GTX and GTS versions have support for triple-SLI. This featurerequires one 8-pin power connector to work, translating into a maximum power consumption of 225 watts for the 9900 GTS (75 watts + 150 watts). According to these drawings, the 9900 GTX could be looking at up 300 watts (75 watts + 75 watts + 150 watts). Of course, we don’t expect either card to actually consume quite so much, but we believe that the engineers have created enough headroom simply to ensure a stable operation of the card. What looks rather strange is the presence of NVIO chip. After the "we do not support HDCP at 2560x1600" fiasco, would indicate that these pictures are fake. NordicHardware ran two stories (here and here) disclosing alleged details of the cards. Reading over those details, we would agree that these pictures fit the bill, at least as far as power consumption and most specs go.
