Summary: Works well and quiet. Never hear the fan. Mounted unit in the top of a modified case with vent holes for best heat dispersion. Six months and no problems. Sata connectors are hard to install into drives, but I hear other units have the same fit.
BIOS shows actual 12v value is 12.614v (more than 5% difference)

Summary: Fan fan is noticeable, and there's sort of bzz sound (my system takes only 150w so it's not stressed). The 12v is wayyy too high, which's a risk - you don't expect such value from a quality PSU. My cheap Chieftec had much better value 12.13v which's on the safe side.
Summary: This unit installed very easily into my fractal design r4 case. It's quiet and provides the appropriate amount of power. Seasonic also included a few large velcro ties in addition to the standard plastic zip-ties for cable management. The only possible downside is that has just 2 PCI-E expansion slots. This was fine for me since I was only using a single graphics card, but anyone trying to run lots of expansion cards will be disappointed.
Summary: Pro: Great and reliable power deliver. Quiet fan. Modular. Con: Coil whine. It is not that bad, and is inaudible over my quiet case fans when my tower is under the desk; however, if you were looking for a truly silent or close to silent system, look elsewhere.
Summary: I am using this in a media computer and a quiet fan is a must. The first unit I received from Amazon had its fan stuck on high, but I returned it with no problem and replaced it with another that works properly. The unit is very quiet. The modular design really helped the cable management in a small case and the price is very reasonable for a 80 Plus Gold unit from a quality manufacturer. Overall I'm satisfied.
Summary: I choose this PSU because: 1. It was a well rated Gold certified unit made by a trusted company. I used [...] to interpolate the efficiency of this model. 2. It is a modular design. 3. It is more than enough for me to grow my PC into.
Excerpt: Po zapojení do nového pc musím říci, že ventilátor na zdroji je extrémně hlučný. Možná mi přišel vadný kus (nevím), ale každopádně ho vrátím. Toto bych nikomu nepřál poslouchat. Samotný zdroj je jistě kvalitní.
