I have a couple of thoughts:
1. since you have no price on the ram, I presume you own the 2 x 8gb kit of 2133 speed.
That is fine, there is little advantage of 2400 speed in terms of fps or real app performance.

You are good.
2. The amp! card is a very heavily overclocked card and requires some 150w more than the normal GTX1080.
The card itself can consume up to 375w.
I am doubtful that 600w is sufficient and the corsair builder series is not considered good quality.
Tier 4, I think.

Try to buy a tier 1 or 2 unit if you can.
Seasonic is always good.
Seasonic S12II 620w would be my minimum, and really, you should go stronger like 750w.
I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
3. The noctua NH-D15 is about the best air cooler around. Probably more than you need.
I would buy the newer s variant which costs the same.
It is redesigned to clear tall ram heat spreaders(not a problem for you).
More importantly, it is slightly offset to clear graphics cards with backplates mounted in the usual first pcie x16 slot.
