This looks like a good power converter. It has solid output current at the main rails, good current on the secondary rails, and tight voltage regulation across wide loads for all rails. It includes a number of connectors, all of which look reasonably well constructed, and things fit together nicely.

Unhappily, the Platinum-860 ATX that I received is not the model advertised here. Yes, it is still a Seasonic Platinum-860 ATX, but there is a tiny (might look like a printing error if you need glasses) additional character in the model number. Instead of an SS-860XP, it is an SS-860XP(2) -- the (2) is actually superscript, and about a third the size of the other characters.

The difference between the SS-860XP and the SS-860XP(2)? The SS-860XP(2) includes the expected system board connector, 1 * 8-pin CPU connector, 1 * 8-pin or 4-pin CPU connector, 4 * PCIe 8-pin or 6-pin connectors, but instead of the expected 8 * peripheral 4-pin Molex connectors, 11 * SATA connectors, and 2 * floppy power adapter, it only includes 5 * peripheral 4-pin Molex connectors, 10 * SATA connectors, and 1 * floppy power adapter. In addition, the SS-860XP can be mounted with the fan either way, so it can go either on the 'top' or 'bottom' of a chassis (with the fan toward the system board), while the SS-860XP(2) can only be mounted with the fan 'up', so it will not ventilate as effectively on the 'top' of a chassis (if you have a desktop or rack chassis, substitute 'left side' for 'top' and 'right side' for 'bottom' when looking at the back). In both cases, the 'y-adapter' floppy adapters are not 'y' but pass-through, which means they consume the 4-pin Molex to which they are connected (a 'y-adapter' would split that into another 4-pin Molex *and* provide the floppy connector).

Originally bought a Corsair 750-TX (a very highly rated PSU) for my recent computer build. First couple of shakedown runs had a coil whine issue - where the unit produces a very high-pitched vibration noise. Returned it for a second one, which had the same problem. Performed several tests to ensure that it was the power supply, at least within my setup (i5-3570k OC'd and GTX 670).

Anyway, I returned that one as well and simply went with buying this Seasonic. Coil whine issue went away- and I have a much better power supply for it.

This one is fully modular: all the cables can be plugged in to the PSU, so you use only as many as you need. Cable management heaven.
The fan has a "Hybrid" mode, which, as I understand it, adjusts the fan speed of the PSU to an appropriate level. This is great for reducing fan noise under lode.
Platinum 80+ certified: this is one of the most efficient power supplies you can find. Savings from this level means that the difference of this PSU to a lower end one will pay for itself after a year (if you sue it as much as I do- which, if you're looking at this power supply, I would imagine you do).
Seasonic is actually the company behind many other power supply brands. Still, they'll save the best for their own brand. I have read some reviews by some more technically-competent individualsthan I who praise the soldering and wiring work of Seasonic units, saying their often the best quality units around.

Highly recommended power supply; easy to install, operates great, and will pay for itself in energy savings eventually.

If you build Computers and you need a PSU there are several brands that go to the head of the
list, Seasonic is one of them. My computers run 24/7 so getting the best efficiency WILL save me money.
This Unit is as quiet as it gets and the power is clean and abundant, if your Tri SLI w/Nividia you may want to
go to the 1000Watt but I did NOT need that kind of power so I save a bit going for the 860watt. You can not go wrong
with this PSU. It us boxed well, has plenty of cables and velcro ties and just is a great PSU.

I love Seasonic (the #1 PSU maker in the world) and this PSU - but I have two issues with this purchase.

First, and this is more of an Amazon issue than a Seasonic one, is that I needed it quick for a new build, and paid extra for two day shipping. It came really quick in like a day and half, but when I opened the Amazon box....WOW. The Seasonic box inside was not sealed and was actually partially opened. The cardboard flaps were open and the contents looked like they had been removed and then stuffed back into the box haphazardly. In fact, the Seasonic box's cardboard was even slightly ripped, and one corner was smashed like it had been dropped. Shame on you Amazon for shipping a premium $200 PSU out like this. It really looked like they sent me a returned/opened item and not a brand new one like I ordered.

Secondly is about the PSU itself. Like I said, I really needed this for a new build - so I went ahead and used it. I had to. The actual PSU looked undamaged and after completing the build - everything powered up and was running fine, with one caveat: I have yet to see this PSUs fan spin. I know it has a hybrid fan system and stays off until under load, but I have stress tested over and over and tried to put the system under heavy load to check for stability issues (unfortunately my office stays really cool, so it never heats up no matter what I do). The computer is great and has had no crashes or BSODs, but again, the PSU fan has never spun once. I've tried the little switch on this unit in both modes "Hybrid" and "Normal." It makes no difference. The fan never spins no matter what. Is this normal? Also - shouldn't the PSU's fan spin for a few seconds when I first turn on the computer. It doesn't.
