Photos show Nvidia GeForce GTX 1080 . circuit board

Photos have emerged showing the circuit board of the Nvidia GeForce GTX 1080. The exact name of the GPU can also be seen on the video card: it is the GP104-400-A1. The pcb has 5+1 phases and seems to have pins for an extra 8pin plug.

Although Nvidia has unveiled the GeForce GTX 1080, the manufacturer has not yet revealed all the details. For example, the exact model number of the GPU was not yet known officially. Photos of the chip, published by Videocardz, now prove that it is indeed the GP104, or GP104-400-A1 to be complete.

Photos have also appeared showing the entire circuit board of the reference design. It shows that the GTX 1080 has 5+1 phases, five for the GPU and one for the memory. That’s more than the GTX 980, which has 4+1 phases, but less than the GeForce GTX 980 Ti with 6+2 phases. The PCB is similar in layout to that of the GTX 980, with eight memory modules on each side of the PCB.

Nvidia uses one 8pin connector on its Founders Edition, or the reference design. That connection is good for 150 watts and another 75 watts can be drawn from the PCIe slot. The video card has a TDP of 180 watts. Additional pins are present on the PCB, possibly a second 8-pin connector. However, it is at right angles to the other connector, or whether these pins are intended for adding a second power connector is not entirely clear. Manufacturers could add an extra power connection to GTX 1080 video cards that are equipped with a significant overclock.

The first pictures of the GeForce GTX 1080 with a custom design have also surfaced. It is a video card from Galax, which appears to be equipped with a simple and cheap blower cooler. It is likely that other manufacturers will opt for multi-fan coolers, just like the current GTX 980 and 980 Ti cards.
