Pros: Near silent operation. I upgraded from a 650w BFG psu and a couple of 120mm nexus fans and the difference is night and day. My tivo's hard drive 10ft away is now louder than my whole computer! When I walk into the room I have to sit down and wait ten seconds to let my ears adjust to the room before I can tell if my computer is on or not. This thing bottoms out my Tenma DB meter!
Cons: 1. The 20+4 pin mobo connector could have been done better. On my BFG the +4 pin could slide and snap into the 20 pin connector to make it a one piece. This one just has a little ledge the the +4 pin can teeter on and it takes two hands to install.
2. Also the cable management leaves alot to be desired. There are a couple unremovable cables like the 2nd sli cable that just take up space if you don't need it. Additionally, the cables you can add on only come in 3's, so if you only need one molex connection you have to install a cable with three connectors.
3. I hesitate to even call this a con, but the only sound I can hear is an almost silent high pitched noise, like someone is using a shop vac 10 miles away. I hesitate to even say this as it is unnoticeable if your not listening for it, and I'm not even sure it's coming from the psu.
Other Thoughts: As to the previous reviewer, I'm not sure its right to blame the PSU for your house wiring. I ran a test: on a 15 amp circuit I have 2 bedrooms and a hall. I turned on all the lights, a 27" sharp lcd, a 32" sharp lcd (my monitor), a 52" sharp lcd, a directv tivo, a sony 6 dvd changer, a printer, 2 external hard drives, a 52 inch ceiling fan on high, an IQair air purifier on high, AND a dyson 7 vacuum. I then hit the power button on my oced 4.2ghz rig and saw no signs of dimming lights or power fluctuation.

Other Thoughts: Just purchased my second Nexus 850 watt power supply and wanted to pass along the readings I obtained from an Antec PSU tester:
+5V = 5.1 +12V1 = 12.2 +3.3V = 3.4 -12V = 12.0 +12V2 = 12.2 5VSB = 5.2 Power Good Signal (PG) = 340 ms
From the BIOS of a P6T Deluxe V2 mobo:
CPU = 1.152 3.3V = 3.328 5V = 4.998 12V = 12.081

Quite possibly the best PSU on the market

Pros: Solid construction, 135 mm bottom mounted fan, professional looking, sleeved modular cables, completely quiet.
I checked-out the voltages using an Antec PSU voltage tester and they were all within tolerances.
When mounted in the case the PSU writing is actually right-side up as opposed to upside down with PC Power & Cooling (OCZ) PSU's.
Cons: Draws a lot of start-up current.
When I power-on my computer the overhead lights flicker in my house and it causes a fairly significant power sag on all equipment connected to the same circuit. My other computer's UPS's kick-in when I turn on my computer or when it comes out of standby.
Requires a large (i.e. 1500 KVA) UPS if you intend to draw close to the 850 watt maximum power draw. This is not really a con but more of an observation if you intend to push this PSU to its limit.
The SATA power cables are designed in reverse. What I mean by this is that you will find when you plug-in the SATA power cables you will be forced to route from the bottom of the case up as opposed from the top to the bottom. This is a minor annoyance but it is reverse from what I am used to with other power supplies.
Other Thoughts: I've been a PC Power & Cooling PSU user for over a decade now. After discovering this power supply I will finally abandon PC Power & Cooling (OCZ) PSU's and go with Nexus from this point forward.
You can tell a lot of engineering and thought went into the design of this PSU. From the larger 135 mm bottom mounted fan to the solid look and feel. When you turn on the power supply you literally cannot hear the PSU fan rotate even outside of the case. I don't think I've heard a more quiet fan.
Be careful when sizing a UPS for this PSU. With 80% efficiency this means that you get up to 20% power loss. Therefore, if you are drawing 850 watts from the PSU the PSU will be drawing 1062 watts from the outlet (850/.80). Therefore, you need a very large UPS to handle this kind of wattage. I am using a APC 1500 KVA UPS but I am only pulling 170 or so idle watts and 230 watts maximum with a Core i7 system.
Would have given 5 eggs if it weren't for the SATA power cables being designed in rev
