GeForce GTX 670 Ti has 300W board power design

The chaps over at VR-Zone are displaying a diagram based on the (what they claim to be) NVIDIA GeForce Kepler 104 (GK104) ASIC, which rpesumably is going to be the GeForce GTX 670 Ti. Apprantly that diagram is showing a 5 NVVDD phase power supply (VRM) design that draws power from 6-pin and 8-pin power connectors.

Up you accumulate that then logic assumes that the board power can peak towards 300W of power as 75W + 150W + 75W from the PCIe connector = 300W That's quite a bit. Phase 1 and 3 will be wired to the 6-pin connector; phase 2, 4, and 5 to the 8-pin connector. NVVDD phases 2, 4, and 5 feed power to the GPU, while phases 1 and 3 power the GDDR5 memory and other components on the board.

Nothing much can be taken from this though, as the boards design power says nothing yet about TDP. Have a peek at the screenshot, courtesy of vr-zone.
