Quiet, modular
I installed this in the Fractal Design Define R2 XL Titanium E-ATX. The one molex that has 4 connectors that goes into the mobo couldn't reach through the back of the case and then in again. So I had to route it the old school way, in the front. The rest manage to stay in the back and hidden. I'm running 6x140's including the heat sink ones, sli 670 gtx 4 gig, 16 gigs ram, 27 inch monitor, ssd, and 2 hdd's. On hybrid it doesn't even ramp up the fan playing games maxed. Still quiet. Actually I cant hear it. Very stable voltages. I would buy it again. I would wait to get it on sale though.

Came packaged really well, even wrapped in a velvet custom bag, and all the cables are neat and tidy in their own little carry case.80 plus platinum - and the hybrid fan mode is awesome, it only really turns on under load, and even then I can't hear it.
Nice front grill covering the fan.
Very cheap sleeve job on the cables, each end of the cable shows about 1.5 inches of un-sleeved cable, the material is cheap as well, like a cheap plastic. I should say I am very very picky with the esthetics of my new rig.
Besides being disappointed with the poorly sleeved cables, it's a great PSU so far, and it's Seasonic, can't really go wrong there.

I was going to purchase all individual sleeved cables anyways, so I can't really complain.

This is All you could ask for in a SeaSonic Platinum 1000w PSU. Powers my dual 680's, i7 980 j4.2ghz, Intel 520 SSD 120GB, 600GB Velociraptor with ease. This is a huge step up from my Cooler Masters 850 Bronze PSU. Love the Hybrid switching to fanless cooling. Fully Modular too. No Complaints
None at all!!!
Best PSU i've ever boughten so far...

Experience: 5 Days
-almost silent under loads
-silent when not in loads
-very efficient
-shorter cables
IF you need 1000w and great efficiency, pick this unit up. Seasonic also makes the xfx version of this and the antec version of this from what i remember so if those are cheap, get those instead since you are basically getting the same unit, but with a different fan

Reliable, 7-Year Warranty, 80+ Platinum, Silent Hybrid fan mode.
There's only 3 Platinum 1000 Watt PSU's out there, and this is the one to get. Compared to the XFX, and ANTEC, it offers Seasonic reliability which is at the time of this review, the best PSU manufacturer out there. However, it doesn't mean the other manufacturer is bad, it's just not up to par with Seasonic; so you should always do a little research to see if you can save a few bucks for your needs from hardware reviewers. In the meanwhile however, I feel that I can use this PSU for years to come, my hope is that I can use it for 10 years at least. For those who's worried about the Power output for over the edge high end system, the power requirement for PC components will only get smaller as technology evolves. So give it a serious thought before you buy a 1200W 80+ Gold PSU

Very quiet and excellent power delivery. High quality construction and lots of accessories.
-Motherboard power cable is a bit on the short side for a full tower case with cable management.
Overall this unit delivers on what it promises. It delivers loads of power while making little to no noise. Seasonic provides a plethora of cables for every type of connection available. Lots of SATA connectors for multiple drives in different locations. The only thing I can possibly nitpick about is that the motherboard cable is a bit short to run through cable management on a full tower case, it still reaches, but the PSU had to be locked in place with the cable attached first.

Quality. Period.
The tears of joy it brought to my eyes got my keyboard wet.
I usually buy Silverstone or Corsair PSUs, and I have found both to be decent. I always wondered why the Seasonics were so much more money. I finally broke down and bought one after my Silverstone packed it in (I was lucky, it didn't hurt my mobo or i7-980 when it went). Now I see why they are so pricey. This thing oozes quality, is super quiet, and I am sure come summer time it will dispense Ice Cream Sundaes. Well maybe not the last one, but I am glad I bought it - it's nice to know I don't have to worry about that aspect of my system for a long time to come.

No coil noise, no hissing.
Quiet. You can even run it fanless (with auto on on heavy load)!
And of course, low heat. Thank you 92% efficiency!
I went to find a good power supply after mine started hissing with my new video cards. I thought first it was the cards but after close inspection I saw that the hissing came from the PS.

I upgrade to this power supply after I read JonnyGuru's review. Basically the best power supply he has tested yet (he has over 230 units tested so far).

No more hissing.

This 1000W PS is smaller than my older 750W. Neat! And way quieter.

tons of cables included, nice little screwdriver, clearly excellent build quality. Very quiet, even on normal fan setting.
price, i suppose.
Best PSU on the market, short of something industrial.

Experience: 1 Weeks
Quiet, powerful, lots of cables, adjustable fan speed profile
Not much to say really, it's a great PSU and makes no coil whine or fan noises. I have this powering a Tri-Fire 6990+6970 build. Just put it in your case and you'll never have to worry about it again.

Comment: Sure, there are higher powered units on the market. Sure, there are a few units that can match this power supplies DC output quality. Sure, there are a few units that are built as well as this unit; OK most of those are Seasonic units too. However, there really aren’t any power supplies with as good
Posted by: Black_ice-Dragon @12/15/12
Comment: Summary Was the long wait for this unit to hit the marketplace worth it? Yes. Have I seen a unit outperform this one for voltage stability? No. There's only one more question that needs to be asked, people: how fast can you buy one? The Good: Extremely good voltage stability - best
Posted by: Paul_T @12/05/11
Comment: Seasonic did it again. Their new Platinum units, judging of course from the sample I have in my hands, are outstanding and definitely worth every dollar (or euro) of their high prices.
