Excellent performance. Not as dead silent as I would have like since my pc is ultra silent, but much better than a typical psu.
When you have psu sitting side ways, the fan makes a slight noise.
Overall very happy with the purchase. There was initial factory smell of VOC but that went away after 1 week.

Experience: 2 Months
 Verified Owner
Looks sharp
Nice sleeved cables with pouch to store extra cables
Silver Plus rating for effeciency
2 sets of motherboard power connectors. Perhaps redundent since only Very high end motherboards would be using both, at which point 850 watts may not be enough for the total rig.
Got this on a sale and read great things about it. I can't say that I have any problem with it. Great modular cables make for an easy set-up. A variety of types too, a couple just sata, a couple just 4 pin with good lengths too them. being sleeved makes for great cable management and it comes with an adjustable cable tie. I'd buy again.

Experience: 17 Days

Lots of power
This is a modular, highly efficient power supply. The price is pretty good for a 850W psu but it could be better. I bought it with a MIR so it'll take awhile before I know the actual cost of the power supply. Very good quality however, worth the cost.

Experience: 3 Weeks

lots of power
cord length
This provides great power for the price....very stable & plenty of veery nicely in the case & looks great

Experience: 4 Months

80 plus silver, easy to setup,
it easy to setup with plenty of cords for beginners to start a computer with. holds the right amount of power for any person building thier first computer.

Experience: 2 Weeks
 Verified Owner
Very powerful, has all and enough of the right connectors you'll need.
Wish it was all modular but hey for the price (price match best direct) it was gerat deal with the MIR. Got it for 129.99 - 40 Rebate = $90

Experience: 10 Days
 Verified Owner
Good value.
Powers my retired gaming machine with 1090T OC'd to 4Ghz 12GB ram, 4890 CrossfireX and 4 hdds. Although it maybe a little overkill for the computer, it's been working fine. Cable management is excellent. Improvement to the TX750 that was originally in there. Excellent purchase if you get it cheap.

Experience: 1 Years
- Lots of accessories
- Modular
- Wrapped cables
- None
Great PS! I used this on my Crosshair IV MB, in a HAF 932. All the cables reach were they need to go, so no worries there. PS looks sweet too, nice green with matte finish on the metal.

Top notch quality

Experience: 2 Months
 Verified Owner
Quiet operation, stable delivery of power to system and very nice colour scheme.
cables are somewhat short if you have a full tower case and power supply sits at the bottom of the case (like the Silverstone TJ07B).
Bought this for my new system build. I was looking for an very good power supply that will be able to give power to my system that I am planning to install multi video card and this fits the requirements. So far so good and can recommend this to people building my kind of setup.

Note: when I first got my PSU, there was a problem with it. Something was loose inside the PSU, RMAed it and NCIX even paid for the shipment to them which was very nice. They immediately ship me a new one without waiting for the defective one to come first.

Experience: 2 Months
seasonic made
modular interface
dead sexy box and accessory pouch and psu itself
Coil whine/squeal
Gotta say, I was amazed when i saw the box, it's like receiving a collector's item of some sort,
Has plenty of modular cables and interface, I was fairly iffy about the psu until i read couple of reviews and a lot of people vouching that this is seasonic rebranded psu, So i pulled the trigger, great choice over all. Love the pouch they include for all the modular cables, I like the color choice, green and grey/black
I have noticed annoying squeal/whine under heavy load or just when I'm folding but I've gotten used to it so i'll let it be.
if you are looking for a great psu for lower price, go for this

Comment: "The XFX Black Edition 850W power supply is an excellent unit that makes for an excellent freshman offering. The Black Edition maintains the excellent voltage regulation and efficiency of the M12D-850 it is based on and then one ups it in the DC Output Quality department."
Posted by: Homer Jay Simpson @07/01/10
Comment: Putting the 80 Plus Silver issues aside, the XFX Black Edition 850W performed admirably. The DC voltage load regulation was excellent, DC quality well within specification, and excellent efficiency of up to 89%. If you are in the market for a power supply to run any high end system with graphics car

Comment: SKYMTL previews XFX's first foray into the PSU market with the Seasonic-powered 850W Black Edition.
Posted by: Dead Things @11/18/09
Comment: In one swoop, XFX has run in and come up with a winner right out of the gate. The Black Edition 850W is solid, quiet, and once it hits the market in earnest the price should go down to the point nobody working for the competition will be able to sleep at nights. I'm still a little bit on the fen
