For that computer I would go for an 5820K, because I don't think paying what the Z170s cost is profitable.
And for that ssd I would get a m.2 2280, with 4x4gb 3200 and that graphics card is now a toy. I would go for what Espinbeteenbolas says: 480 or 1060 if there are no bitches and a 1070 if you can stretch.
Power supply considering the consumption these micros and graphics cards have now you are more than enough: we are talking about about 200w in motherboard and micro and other things, and 200w from the graphics card.
