The verdict
If you're running a top-end graphics card and want plenty of headroom, the HXi gives you 1200W or 1500W with Platinum-level efficiency.
HWBusters and Tom's Hardware both found it very quiet and well built, with strong power delivery. HWBusters likes the USB-C monitoring, while Tom's Hardware calls it gimmicky.
Check your case first. Tom's Hardware notes it's 200mm long, which some cases won't take. HWBusters also wants better transient response at very high loads.
