Quiet and does the job on my OC Devil's Canyon system

Summary: Power my system with No Noise. Trouble-free. I'm not stressing it, driving an ASUS 750 Ti, an ASUS Z97 Pro mobo, and a 4790K OC to 4.7G (about 140W for the CPU). This p.s. has a "hybrid" mode of cooling, where the fan doesn't spin if the temps are below a particular threshold. At idle, my system doesn't draw enough to turn the fans. At full load, the CPU cooling fans make more noise (not much, though) than any the p.s. might be making.
Summary: Great power supply. 850W is plenty to drive my EVGA GTX 980 FTW and i5 4690k with plenty of overhead for the rest of my system. I had to upgrade my previous 650W PSU which was a Kingwin because my PC was rebooting without warning during intense load. It's hard to know what effect a finely built PSU can have on a system but rest assured that the build quality and materials used in this PSU are great.
Summary: Ordered this to replace a Corsair power supply that had extreme coil whine problems when under certain types of load (SimCity 4 turned my PC into a headache machine but it was silent while running Skyrim with 50+ mods.) This power supply was a dream to install with its modular cable design, had way above average build quality and even came in a nicely built storage bag which holds the extra cables after install.
Summary: Awesome modular design. Awesome variable fan to keep the volume of the system low unless it's really working. Awesome power supply. I would buy this again without hesitation. In fact, I did when i built a friend's system recently.
Summary: I put a lot of research into this before purchasing a power supply. The Seasonic units are among the best. The unit was packaged wonderfully, plenty of connection cables for the motherboard, video card, and other items. Installed fine. I was so impressed I ordered a second unit later for my second PC build without hesitation.
Summary: First one failed shortly after a year; a capacitor just randomly blew up. Aside from it blowing up within a foot of me, the only thing I can complain about was that it suffered from coil whine. At that point, I was still willing to trust Seasonic for further PSU purchases. I filed for an RMA and received the replacement within a week. Wow. I figured, Seasonic must really care about its customers. Wrong. The replacement I received was a dud as well.
Summary: First time buyer of Seasonic and I'm very impressed. Works like advertised and I feel confident based on the observation of how well the unit looks and the quality of the contents included; the module cables even come with their own carrying case (minor, I know, but adds to value). I used this on a server setup with the non-hybrid option enabled.
Ferrari of the PSU world. Fantastic Ultra-silent Power Supply. Extremely high quality.

Summary: Replaced the PSU in my 6 yr old Alienware gaming PC because I got tired of how loud it was. Seasonic is completely silent. In HYBRID mode, the PSU will decide whether it needs to run the fan, which it rarely does on a system comprised entirely of SSDs. The impressive packaging tells you this is a high end part. Ample cabling and even comes with plastic ties to tidy things up (nice touch). I couldn't be more impressed with this beast.
