looks good to me, I'd replace the H80 for a big air cooler (Nocua DH perhaps), and you don't need a 1000W PSU at all. a 500-600W Is all you need for your build
I'll suggest the SeaSonic S12 II 520W model.
Someone told me that more power equals better performance which is why I chose 1000w. Is that not true?
And isnt water cooling better than air cooling?
