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.

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

Pros Nice mid-range power output Sweet modular cables!
Cons A bit expensive No real instruction booklet
Summary 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.
Pros works, got it comboed with a hydro cooler, modular
Cons the 4/8-pin power cable is a bit short. unable to route through the back of the case
Summary 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.
Pros Lots of power and Seasonic has a good reputation for high-end PSUs. Price.
Cons 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.
Summary 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.
Summary 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.
Summary 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.
Summary 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.
Pros - 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
Cons - None, and I hope it will stay that way
Summary 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. PSU used in: Case: CM 690 II Basic Mobo: ASUS M5A99X Evo Memo: Corsair Vengence 2x4GB 1866 HSnk: CM 212 Evo This review was modfied by poster a 05-20-12 01:08 AM

Summary This is some really good PSU ! Its modular and easy to do the cable management ! Buying from Seasonic is often cheaper than buying from Corsair and it does the same excellent job.
Summary after more than 20 pc built, I learn you can never cheap on a PSU, my Antec 500W can not handle my new upgrade-- GTX 570 with a I7 960, so I`m either getting this or the Corsair(made by seasonic), with this price I would say its well built,really quite, cables are long enough for my Antec p192 case,I`m very happy with it
Pros Easy and fast setup Modular design makes cable clutter non-existent So quiet, pins dropping are louder
Cons Slightly large for my case
Summary Had to upgrade my power supply to support a PNY GeForce 560 Ti video card, seeing as my stock power supply was 300W. Went with this based on reviews and a PSU calculator. Quite simply, it's the best bang for the buck, dead simple to set up and work with, and AMAZINGLY quiet. You won't regret it.
My only complaint is that it's slightly large for my case, but that is really something minor and no reason for Seasonic to lose points. Will definitely be investing in more Seasonic PSUs in the future.
Cons Price is a little high but you get what you pay for.
Summary Seasonic is one of those products you buy and never worry about. I have always purchased their power supplies and never had problems. Will continue to buy again.
Pros Good price, a lot of room for power, 2x8pin for dual cpu
Cons Not 4x 6pin PCIE is kind of a deception since a 600W PSU can easily handle dual GPU
Summary Running a x4 925 (AMD) at 3.4GHz and 2x5850 without problem. The psu is one of the best for the price, not gold but wouldn't have advantage to have a gold over this one any way. A lot cheaper than the corsair it's in my opinion the best brand so I don't see the point buying another psu except for higher power. Silent as death and immortal definitely a must buy for anyone having a system requiring power, was using a M12II 430W before and it was enough before the crossfire.
Pros stable, attractive, mostly modular, quiet at moderate loads
Cons a bit loud when under stress
Summary Over all, this has been a very strong PSU for the three months I've owned it. It has lots of cables with decent length and the sleeving isn't too bad either. The unit is also aesthetically appealing--no Michael Bay Transformers look for this component; it's simple yet refined and also seems solidly constructed. My voltage readings (according to HW monitor) never vary beyond spec even under heavy loads.
Regarding noise levels: The fan is silent 99% of the time even though I've got the unit installed in a case with somewhat restricted airflow. However, when I loaded my PC (OCed 940BE and a slightly OCed 6870) to the max with OCCT GPU test and Prime95 at the same time, the fan did noticeable noise. I'm not sure how much juice the system was drawing at this point, but I'd guess around 400 watts.
Overall, I'm pleased with this purchase. Will buy Seasonic products again for sure.
Pros Good quality, nicely packaged, good length cables for a mATX case, lots of SATA connectors, two 6 pin PCIe connections (one with additional plugs for 8 pin), quiet, 5 year warranty
Cons PSU is longer than the specs state (W150xL160xH86 mm)
Summary This was bought to replace a failing Silverstone ST-50EF-SC (short cable) in a Dell Studio 540. It arrived this morning (thanks NCIX - you guys rock!) and was nicely packaged.
First issue I had was that I was expecting the dimensions to be 150x140x86 and in fact the 620W version is 150x160x86 - so anyone wanting a short PSU be aware. This is not listed on the Seasonic website either!
In my case, the Studio 540 case has 2 metal lugs just behind the PSU, built into the frame, designed to hold the PSU in place. They are 140mm back from the rear screws which is why I was after a 140mm PSU. With that said, and a little brute force, the PSU went in really easily and the notches have not caused any issues for the PSU or the mounting (sweet!).
For a "normal" ATX power supply the cable lengths are actually fairly short - somewhere in between my old Tagan 580W (long) and the ST50-EF-SC (very short). I was easily able to route the ATX 12V lead between the motherboard and PSU and the main power ribbon lead behind the HDD. The main cable bundled (ATX12v and the ribbon) are not modular and are permanently wired - however it is wired to the far side of the PSU so in my case (mounted at the top), the tethered cables are away from the modular part which makes it slightly easier to work with. The PSU has an actual on/off switch too.
All cables are sleeved (and come in a neat little draw-string bag), but only the Molex power connectors have the "easy swap" feature. There are 2 PCIe power leads and one has a 2-pin adaptor. You can either have 2 6 pin PCIe or 1 6 pin and 1 8 pin. You should be good for pretty much any single card on the market - unless it needs 2x8 pin PCIe connectors.
There are lots of SATA connectors and there is a good distance between each one. I am using only a single SATA power lead to connect to both the single HDD and the DVD drive in my system.
All in all, I am so far very pleased with it. It is extremely quiet and seems to be pretty stable for voltage based on some very rudimentary initial checks. It took a little effort to route the cables because they are new and not immediately flexible. For an mATX case it works great as the cables are not too long and leave lots of room for air-flow. If you have a very large tower you might have issues though as the cables are not extra-length, so be sure to check what lengths you need first.
Summary After trying cheaper options as well as more known brands which all failed, I decided to do my research and everyone seemed to praised Seasonic so gave it a try and was pleased. Do not be fooled! This PSU has solid performance is quiet and handles a heavy load very efficiently. You cannot go wrong with this one. Seasonic is the only way to go for PSUs! Yeah, they are pricier but you get what you pay for. I rarely write reviews but in this case I felt the need to spread the word.

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
