The rebate that was available by the manufacturer at this point and time was also making it a great deal for a 80+ Silver 850W modular PSU. Surely more and more 80+ Gold units are getting more affordable, but 2% efficiency difference will need more than 5 years of 24/7 operation @ 400W load to make up the $50 or so added initial investment - at least in the continental US were electricity is dirt cheap.
Building quality appears to be solid, and the cables were easy to tidy up in my CM 690 II. Keep in mind that the 8pin CPU cable (part of the non-modular bundle) was a tight fit in this case and a Asus P9X79 Pro motherboard. Users of bigger, full tower cases might have an issue with that an could require an extension)
Some people complain about semi-modular PSUs but I doubt that anybody will be likely doing without the 24pin motherboard connector or the 8pin CPU connector, while most cases can easily hide those behind the motherboard tray.
Unfortunately I was unlucky with my purchase, and got a defective unit. After experiencing weird ripple on the +5V (at least that's what my eye caught), I had the PC shutdown itself while under F@H load in the middle of the night. Seconds after my attempt to reboot it, a loud noise - probably from a capacitor blowing inside the unit - killed the PSU. I do believe I was unlucky, as there are numerous satisfied users of this line of XFX PSUs in enthusiast forums, yet having this happen to you on a unit that was out of the box for 4 days, and really working for around 20H, is something I wish to no-one. No other component was killed by this failure (CPU/Mobo/Wifi Card/RAM/GPU/SSD/HDD) all working fine.Read more ›
The only complaint I have is that the 8pin mobo cable is too short, had to extend it. Also the cables are kind of stiff, almost like they used solid cable instead of stranded in some cases.
Brand new PSU, will update after a few months. Also, to re-iterate, the PSU is SILENT.
I've added a pic with a few notes.
I had an issue with the mobo giving me the re-reboot whenever I turned on the PC and contacted XFX for some assistance to see if it could be their issue. They were very helpful and alway replied to my messages even after we identified the mobo was the issue so I'm very happy with their customer support.
Haven't tried it on full load and I've had it for about 2 months now.
