Pros
Fully modular, less clutter with cables. Stable under load.
Cons
SATA power cables are too short for my case/mobo!
Summary
I have a Fractal Design Define R4 Black Pearl.

I have 6 SATA HD and two optical drives.
The SATA power cable with two connectors is too short altogether: if I use it for the optical drives, it's about 4 inches too short.
If I use the 4 connectors cable, one of the connectors becomes unusable because of the distance between the optical drives and the HD and I had to use the ATA cable with an adaptor to power my top optical drive.

I purchased a new PSU because I wanted to have a nice, clean and easy to maintain setup. Unfortunately, it won't happen with this case/mobo/psu...
Looked around for custom cables and the prices are crazy. Emailed XFX support and awaiting reply.

Pros
Looks nice?
Cons
stopped powering my motherboard, Coil whine
Summary
Bad experience with this psu, experienced coil whine which I couldn't stand, and shouldn't be an issue with a good quality psu.
Apparently Seasonic oem based psus have this problem often so I now avoid them.

I then turned the psu off and it would not power up my motherboard again after that. I reinstalled my old coolermaster psu and everything worked again.

NCIX refunded me with no problems.

I now have a BeQuiet powerzone psu and that is miles ahead of Seasonic.

Pros
Very efficient and good for the price
Cons
None
Summary
Very satisfied with this purchase. This will pretty much be able to support and dual gpu builds at the moment. This unit is also manufactured by Seasonic, one of the most reliable and reputable manufacturers for power supplies.

Pros
Fully Modular
80Plus Gold
Active or hybrid fan mode
Flat Cables
Cons
A minimal amount of coil wine-only audible when computer is asleep
Weird 24 Pin Motherboard connector (half of the 20 Pins in the top group, 4 Pins in the bottom group
Summary
This is a great power-supply.
With it having the active or hybrid fan mode (so when your computer is idling or doing minimal load, the fans off) it's a very nice and quiet PSU (can't be heard over over fans).
The cables are fully black (not sleeved black, the cable's plastic coating is black) and are flat.
The problem is that the 24 pin mother board connect is sleeved, and not flat, but it still uses the black cables which is nice.
Also, for some reason, 20 Pins of the main connector connect to the top row of connectors, yet the last four pins connect to the bottom row on the PSU. Weird
Each PCI-e connect has two 6+2 pin connectors on the ends, making it possible to run almost every card off a single cable.

All and all its a very nice power-supply that's quiet, flexible, and efficient. Plus, it's one of the cheapest power-supplies (in price, not quality) that is fully modular and 80 Plus Gold.

Pros
Outstanding Quality for a Seasonic KM3 Clone with what appears to be a Corsair Classed Casing and Painted Richly.

Really nice Ribbon Cables - Tad Stiff but no problem.

I think XFX has a Winner here with their BBEFX Series
Cons
NONE
Summary
I bought it last week on a NCIX Weekly Special for $119.49 - Thank you NCIX ;o)

Somewhat overpowered for my range but at that price the PSU will operate with Platinum Efficiency and provide me with the option to expand.

You can tell it has Quality just by the Weight and Finish.

I can't see spending $50 or $80 more for a KM3 Seasonic or Corsair when you get the Identical Unit from XFX with a 5 Year Warranty.

It doesn't come with the Velvet Bags but the Packaging is more then adequate.

I actually received my order before PayPal withdrew my payment from my Bank Account and the shipment was delayed one day due to a Winter Storm.
