I don't think you'll have any issue with that set of hardware. If you've never done water cooling before then you'll be very happy with your H80i purchase. I have a Corsair Hydro H100i in both my Linux and Windows boxes and absolutely love them. I'll never do anything but CPU water cooling anymore. Also I would recommend the 850 Evo vs the 850 Pro. The pro's are typically more expensive and only offer slightly better write performance [1]. I've bought over 10 850 Evo's over the last few years and never been dissatisfied with any of them. Just my personal opinion, but thought I would mention it.
Thanks,
