My 3rd seasonic 860 platinum

Absolute joy and efficient PSU. As surprising as it might sound for people, the precision of this unit actually helped me get more stable Overclock on my 3930k in the last 5. Never had any issue from my 3 units. Clever hybrid fan option. very quiet and modular.

Experience: 7 Weeks


-Ultra-high, 80 Plus Platinum rated efficiency.
-Delivers the closest to advertised wattage of any power supply I've ever used.
-When set to Hybrid Mode, the fans rarely spin, even under high load.
-When the fans do operate, they are whisper quiet.
-Huge selection of modular cables that allow connection of any mix of components.
-7 year warranty.
-While the warranty is great, Seasonic's RMA process is a hassle and expensive.
I've been building computers for 20+ years. People often underestimate how vital a quality power supply is and I always buy high-end when I can. This is far and away the best power supply I've ever used. It's so high efficiency that the fans almost never need to turn and when they do, you basically can't hear them. Most power supplies are not able to deliver the maximum wattage they advertise but this one pretty much does in all the tests I've run. The modular cables are vast and a snap to use. It even looks nice and sleek if you have a system that has a windowed case.

My only complaint is that while it has a ridiculous warranty, Seasonic's RMA process leaves a lot to be desired. I had to send another unit in for repair that was damaged by a power surge. You create  an RMA online, then have to send it to the middle of California at your expense (there is no advanced replacement option), wait at least 2 weeks with no way to track the status and if they can't find a problem, you have to pay them a $25US fee before they'll ship it back to you. The chances of you needing RMA service are very small but given the price of these units, it's ridiculous that they don't offer better service than this.

I can't recommend Seasonic enough. They're pricey but the quality and features are the best in their class. If you're building a powerful system, get one.

Experience: 7 Days


Super efficient
packaged great
ample power
very quiet (as in can't hear it)
None except maybe price, but you get what you pay for (stick with none)
I was hesitant for a few reasons, price and worry about coil whine.
I am glad I purchased this unit. Build quality is exceptional and this thing doesn't even make a sound. I have no coil whine or maybe my old ears just can't hear it. One guy reviewed it whining about the cables were to stiff to bend to attach. Really??
Buy this PSU and you wont be disappointed.

Experience: 30 Days


Quiet, Modular, plenty of cables
Installed easily. The wrapped modular cables were long enough to easily route through the case's cable paths (Fractal Design Define R2 XL). PSU runs silently even when powering 2 GTX 680's.

And the Velvet Bag it comes with can hold your oversized D&D dice.

Experience: 3 Months


Quiet, power to spare for my usage.
none found yet
It works! And it's quiet! Seriously packaging is overkill but someone could say they don't mess with their finish.

Experience: 7 Days


Sleek, fully modular, easy to install, silent
Some cables were a tad too short, and I couldn't route them behind the mobo tray
From the reviews on the Internet, this is one of the best consumer power supplies you can buy, and I can see why. Not a single problem or complaint from it since I installed it for my new build. 860 watts also provides plenty of headroom for a decent future upgrade.

Experience: 1 Months


80+ Platinum, Quiet, Seasonic!
I love this PSU... I've used some Corsair and Seasonic gold PSUs, and this is definitely a little step up. Quiet, reliable, with fully modular cables and enough power for a beefy system. Huge Seasonic warranty in there as well. Would definitely buy again!

Experience: 2 Days


I don't hear it! at all! :D
7 year warranty.
Excellent quality
Snap connectors.
Good looking with sleeved cables, also nicely long.
Cool case sticker.
None so far...
Maybe a bit pricey but it's worth it
I may have more to say in some years, we'll see.

Experience: 2 Weeks


Elegant neutral coloring adds nice aesthetics
Fan modes for noise options

Not Cheap
Seasonic is already known for making some very top-notch power supplies but this one has done it. The platinum rating means that the power supply is the best power/dollar around.

The fan controller definitely keeps me happy. It's "hybrid" option is sweet and I never have any problems with it. With the case fans off, The only thing I can hear in my room is the tiny buzzing sound from the monitor/router (whichever one it is).

Love Seasonic and this power supply is a must for any high-end PC.
