the aib's will have multiple pin connectors. i think nvidia went with a higher price and single power connector on ref cards so as not to cannibalize aib sales.
I don't think it's gonna happen from what I've seen so far, all custom pcb's seem to have a single 8 pin connector atm but please do post here in the thread if you find any, fingers crossed I do hope they show up soon enough.
GPU's nowadays come with cables for people not having dedicated GPU plugs.
That was the point I was making, people with newer 500w+ PSU's need not worry, my comment was aimed at people with older PSU's.
GPU's come with molex to 6 pin power connectors for the peasants not 6 pin to 8 pin connectors because that isn't recommended by anyone at all.
And people who are going to buy the GTX 1070 for $379-$450 are surely gonna have or can afford a good PSU.
It's a high-end gpu here because it'll cost 10k more than in the US but it's still a gpu aimed at the mainstream segment.
If you already have a 3 year old gpu worth 5k you shouldn't have to upgrade it just because of the lack of an 8 pin connector when you have the necessary 12v rails to run the gpu with a 6pin + molex to 6 pin setup that can run the gpu comfortably.
Plus how will it bottleneck a gpu if it's more efficient than the one you are already using.
