NVIDIA GT300 TDP just over 225W

BSN claims NVIDIA's upcoming GT300 will have a TDP of just over 225W. In case of upcoming high-memory configurations nVidia Tesla, Quadro and GeForce cards, the company had to install a 6-pin and an 8-pin connector, getting 300W of power to play with. However, this was a precautionary measure. According to information we have at hand, the GT300 board barely missed 225W cut-off for the 6+6 pin if the board comes with 6GB of GDDR5 memory.

nVidia could have gotten 6+6-pin configuration and still ship 6GB version, but the margin of efficiency would be just too low [even with digital PWM, boards cannot be 100% power efficient] to qualify inside OEM systems. The decision was thus made and the 6GB cards come with 300W of available power.
