Asian website fbykj.com have leaked a picture of a mysterious PCB which
closely resembles the GTX 480 PCB. The notable changes are in respect to
the power components.
While Nvidia's official TDP for the GTX 480 is 250W, that figure is more indicative of a "typical power consumption" than a maximum possible. We have seen several reviews showing the GTX 480 consuming about 300W in stress applications. While these applications aren't realistic for everyday usage, they do represent the "worst case scenario". It is clear that the GTX 480 is right up to the limit of the PCI SIG standard of 300W and 6 pin + 8 pin power configuration.
The most logical explanation for this PCB is that it is a non-reference overclocked version of the GTX 480. By sporting 2x8-pin PCI-e connectors and 8 phase power, the PCB pictured above extends the power consumption capability to 375W. It is most likely a non-official non-reference PCB from one of Nvidia's AICs.
Of course, it is also possible that this is the rumoured GTX 485 with all of GF100's 16 SMs and 512 SP / 64 TMU enabled. However, it is doubtful whether Nvidia will release an official product that is not PCI SIG compliant.
