Pros

80+ silver
850W
Cons
Annoying coil whine
A lot of non-modular cables, can take up space and get in the way
Summary
I picked up this power supply to replace an old 470w. Seasonic supplies are typically well reviewed, however upon installing mine I immediately noticed a high pitch "coil whine" emanating from it. I RMA'd the power supply and the replacement I received still made the same "coil whine", although it was less noticeable. At this point, I've decided to just live with it for now.

Pros

-Quiet
-80+ silver
-850W
-nice and heavy
-sheathed cables
-made by seasonic (what more is there to say)
Cons
-the cables are a tad short
-not really sure if its 70A on a single rail or 40A on dual rails
Summary
I bought this to replace two power supplies I had in my gaming pc. Finally I got away from running dual PSUs to a good single PSU. My one real complaint is that the cables are a bit short. The 24pin power was too short to be run behind the mobo tray in my antec 1200 (full tower atx). However it still reached just fine when not behind the motherboard.

Pros

Very Long Cable, Very quiet for a 850W, 80 PLUS SYLVER,
Cons
Not realy a weaknesse, just lots of cable, Power Supply was build for Mother board use as server, to many for a hardcore gamer. Could be hard to put Cable away on a mid size tower.
Summary
I will recommend these Power Supply to anybody, Was a very good price when bought it, very quiet, very efficient, cable are longer then normal Power Supply, a very good choice for hardcore gamers

Pros

Powerful enough for any home system
quiet
stable powr
Cons
expensive unless bought on sale
Summary
I bought this ps for my sons gaming pc after some trouble starting the pc with an antec 420. His system consits of an ovrclocked amd2 cpu, Nvidia chip based mobo and a 4870 gfx card, 500 gig sata wd hd and a few large fans in an icute case. This seasonic ps slipped in easily and offers more connectors than he'll ever need, His system started up first push of the button and has no problems since. system runs stable overclocked and is cooler to boot!
excellent power supply with expandability in the future

Pros

More then enough power for most everyone's needs, Very Quiet, Nice and cool, Solid construction, Enough SATA and PCIE connectors for most needs.
Cons
Large amount of non-modular cables can make cable routing a challange.
Summary
I'm very impressed with Seasonic's PSU. I've been using Enermax for the past 3 PSU purchases, and I have a pretty high expectation from my PSUs. I'm impressed with the quality of this unit. I was running into trouble with my old 450w supply and my Radeon 4890, so I bought this one on sale. Needless to say, unless you have a very small case, I recommend this one highly. It has lots of overhead for overclocking.
There are a lot of fixed cables, so you might want to look at a modular PSU if you have a shortage of space, or like to reduce cable clutter. But for the price, you can't beat the quality.

Comment: With new graphics cards on the market from ATI and upcoming units from NVIDIA, the GPU industry isn’t the only one that is flourishing. While these new cards are more efficient than ever, better multi-card scaling means the insatiable need for more power hasn’t stopped and if anything it has increas

Comment: The power supply is the most important peice of computer hardware we will ever purchase. Having too little of a power supply in our computers, can give us lower performance levels, overheating, lock ups, crashes, to all out torching of our most valued computer components.

Comment: Seasonic touts the S12D-850 as a power supply that should be used in conjunction with power-hungry multi-core processors and dual-GPU videocards, and given this PSU's 850W capacity, PCSTATS is inclined to agree.

Comment: Stable, quiet, rock-solid power supply. Only drawback is the non-modular design.
