They are both Tier 2 PSUs, a good choice. I recommend the 850 watt. However, I cannot say for certain that it will be a perfect choice as I do not know the amperage requirements per connector of the R9 4xx series

Can't you try to find that for me on the web please? I tried with no luck but it seems you guys know just where to look!

The R9 490/x will be much better on power consumption. I expect them to be at GTX 970 consumption level and therefore either one will do fine. However, they seem to be the same price so get the higher wattage. (Evo)

Specs?

Well we would expect the specs of the 490x to be on par with the GTX 1080. Nothing regarding the performance of the 490/x has been released and therefore we just have to assume. I believe that the 490x will perform the same as the 1080 because the 390x was very close to the 980 and this year AMD have the advantage in their finFET architecture. It is also likely that the 490x will be better than the 1080, because AMD executives have indirectly stated that they are not impressed with the Geforce of this year.
AMD MAY hit a homerun this year, but that is only my own thinking.

I do not know how much the 490x will consume, but since they have made revolutionary improvements on power consumption, i feel very safe to buy myself a 490x with my 750w evga psu.
I hope this helps!
