Experience: 1 Years
None really
The quality seems very good. I have heard Seasonic is one of the best psu manufacturers and actually builds them for other brands. It comes with plenty of cables, much more than I need.

Experience: 3 Days

Nice design. This is the first Power Supply with seperate/independant cables. You only install the cables that you need.
Maybe the wire bundles could be FLAT. It would make the RIGHT side panel, in my case, easier to close.

Nice mid-range power output
Sweet modular cables!
A bit expensive
No real instruction booklet
It was bought for my first build, and I am very satisfied with it. 620 W is a nice mid-range power output, meaning I can add pretty much anything that's not too video-intensive and it should have enough power to keep it going.

Modular cables are sweet, but being new to building my own computer, I had to research a bit to know where to plug each cable.

works, got it comboed with a hydro cooler, modular
the 4/8-pin power cable is a bit short. unable to route through the back of the case
i m very happy with this. initially i installed it upside down, because the instruction book wasnt too clear. But i guess any psu is installed the same way, so it didn't even bother to explain that.

Lots of power and Seasonic has a good reputation for high-end PSUs. Price.
Modular cabling is of little benefit. Some unused cables are not modular. Heatshrink would have made for more pleasant feel and cleaner look of the cables.
I bought the modular version thinking that it would cut down on clutter, but I found the modular cables more trouble than normal cabling as with 2 hdds, 1 cdrom, a PCIe graphics card (2 plugs) and a system fan that requires a 4 pin molex, I used most of the cables anyway. And there are cables that are not modular that are unused.

Quality Built
What is there to say, it's a PSU. The modular cables are really nice. It is my first modular PSU. When you get your hands on it, you can tell immediately that this is a quality component. Much nicer than any PSU I've ever owned. Let's hope this one lasts a while. My only regret is that I payed full price. I wish I could have bought it on sale.

Stable power supply. Really quite, no problems with it what so ever
Provides stable power to my PC and is semi-modular which is a nice feature. Fits perfectly in my Cooler Master HAF 912.

Powers my: i5-3570k, GTX 660TI, Z77-D3H.

-Virtually silent
-Solidly built
-Seems to be on back order most of the time
Seasonic is one of those brands I keep hearing about that everyone seems to love and no one has had a bad experience with. I've only owned this power supply for a month now but I have no reason to argue. It does it's job silently, has given me no trouble, and has sleeved modular cables that are easy to work with. You can tell by the weight and feel of the power supply itself that it has a good built quality, and I'm expecting this piece of equipment to last me a long time. Lets hope it does.

Great power supply
Fairly power effecient
I've had this for 6 months running in two machines. Works great. Modular really helps with the cable management. Sufficiently powers both i7 Systems. Was on a budget or otherwise would have got at least a gold level PSU.

- Semi-Modular (24-pin power & 4+4 & 8-pin are attached)
- Type of modular interface between PSU and cable-end connector
- Cables are quite flexible
- 8-pin cable reached 8-pin power socket on motherboard (NOTE: would need an extension if going with a full ATX case and LGA2011 ATX board, as the 8-pin power socket is further forward on the LGA2011 mainboards), when routing thorugh the back of the case
- Well arranged SATA power cables; 3 per cable
- All the power cables/harnesses are a joy to attach
- None, and I hope it will stay that way
Like the previous reviewer said; why go with Corsair when you can go with the company that makes the top-end Corsair PSU's - SeaSonic.

Comment: The Seasonic M12II-620Bronze is a new midrange power supply from Seasonic that has most all of the characteristics we have come to expect from Seasonic. The unit features a large single overhead fan that is quiet, has good efficiency values, a semi-modular design, and enough power and connectors to
