Well, that is one possibility. If it is truely the faulty of the GTX 780Ti, and that it tried to draw too much power through the PCI-E connector, I would guess that it had something to do with nVidia's new "Power Balancing" feature, which is supposed to balance power requirements between the 6-pin, the 8-pin, and the PCI-E slot.
However, it is very possible that it could have been a failure on the Asus motherboard or when they installed the card (maybe some conductive schmutz fell in the slot), don't know.
Heck, it could be a manufacturing defect too. Having one card fail doesn't concern me much.
But, from an engineering point of view intrigues me.
By the looks of it, it looks like the cause was MAYBE on the pin 4&5 of the B side, and/or pins 3,4 & 5 on the A side.
That corresponds to +12V, Ground, Ground, TCK, and SMCLK.
Honestly, if I thought it was the failure on the part of the new "Power Balancing" circuit, I'd expect a lot more burn on the pins 1, 2, and 3 part of that connector and not more in the 3,4, and 5 area. But that is what people who have access to the card and designed it will have to figure out.
