The HX series are good PSUs (I have a HX750W in my current case) but they are semi-modular; full modular is easier to work with. Also, the AX series (not the ones with the i on the end) has a switch that lets one choose between letting the PSU fan run all the time or having it run only when the PSU temperature and/or load increases to a certain point.
You'll never wish for anything else once purchased.

The semi-modular doesn't bother me with the HX850-80 as the one cable that's not removable is the one I'm always going to need and that will always run the same way. OK if that cable dies I have to replace the whole unit but that's very, very unlikely. The HX850-80's fan only runs when required as standard so I don't mind missing the switch either.
I have the Gigabyte G1 Sniper 5.
Anyway if you get that board (B85 Gigabyte G1.Sniper B5), make sure it has the correct BIOS to accommodate the i7-4790K processor. For the Sniper 5, it's F9. For that board it should be at least F6, depending on the revision - GIGABYTE - Motherboard - Socket 1150 - G1.Sniper B5 (rev. 1.x). If it's rev 1.2 you should be safe. Remember these boards came out before the 4790 processors so check the BIOS, especially if it's rev 1.x.
BTW this is a great thread for anything dealing with those boards - [OFFICIAL] Gigabyte G1. Sniper 5/M5/B5 Owners Thread/Club
Good luck with the new build.
Peace
