Hyper 212 EVO is a crappy CPU cooler and if you get i7-7700K, it won't be enough to cool your hot running CPU. I'd go with Be Quiet! Dark Rock Pro 3 or any other big-sized CPU air cooler,

I have Arctic Freezer i32 cooling my i5-6600K, which is 2nd best mid-sized CPU cooler. And i don't think that my Freezer i32 would be enough to cool i7-7700K CPU, even when i run in push-pull configuration with 2 fans installed (as i'm currently running it on my Skylake build, full specs in my sig).
Though, for i5-7600K, the Arctic Freezer i32 in push-pull configuration would be a good choice,

Btw, i love the case you have. Not because it has great build quality but because how fancy it's looking.
As far as your PSU goes, i need to know which dedicated GPU you're planning to go with. If you're planning to go with RX 480, GTX 1060 or GTX 1070, the 600W PSU will do. But if you're planning to go with RX 580, GTX 1080 or GTX 1080 Ti, 650W PSU would be better choice.
Though, when to be honest, your new system is high-end rig and i wouldn't use the mediocre quality (Tier three) Antec VP series PSU in it. The lowest build quality i'd be comfortable using in such a high-end rig would be good quality (Tier two) PSU,

That being said and after looking around in Amazon India, i suggest you go for Seasonic M12II-750 EVO PSU,

Seasonic M12II EVO series PSU is good quality, fully modular, 80+ Bronze certified PSU that comes with 5 years of warranty from Seasonic. 750W is more than enough for any single dedicated GPU you're planning to go with.
All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic. Got PRIME series in Skylake, M12II EVO series in Haswell and S12II series in AMD.
