80 PLUS Platinum, clean, stable power
Complete Digital Control
The revolutionary AX1200i is the first desktop PC power supply to use digital (DSP) control and CORSAIR iCUE to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX1200i makes on-the-fly adjustments for incredibly tight voltage regulation.
Real-time monitoring and control with CORSAIR iCUE
Put the AX1200i under your control by connecting it directly to a USB header on your motherboard with the included cable, or to a CORSAIR Commander (available separately). Then, download the free CORSAIR iCUE Dashboard software for unrivaled power supply monitoring and control options.
Stable and reliable power delivery
DSP-controlled, real-time voltage regulation helps ensure that your valuable components receive clean, stable power.
Less heat and lower operating cost
AX1200i's extreme efficiency earns it coveted 80 PLUS Platinum certification. Less wasted power means minimal excess heat. This can reduce the strain on your other components, and it can save you money over the long run in the form of lower power bills.
Quiet operation at low loads
Super-high efficiency has another benefit: silence. The thermally-controlled fan doesn't even spin at low loads. It's ideal if you're building a quiet PC or you just want to reduce the amount of ambient noise in your life.
Easy installation and cable routing, with better airflow
The fully modular cable set allows you to use only the cables you need, and the flat design makes cable routing much easier in tight spaces. You get a clean-looking system build with cables out of the airflow path for efficient space usage that's energy efficient as well.
Intelligent Control. Unlimited Possibilities.
CORSAIR iCUE provides in-depth PSU voltage and performance monitoring, as well as stunning system-wide RGB lighting synchronization.

Features
Advanced Fan Design
An ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature.
The AX1200i is so efficient that the fan doesn't spin up until you're pushing your system hard. And, fan speed thresholds can be adjusted with Corsair Link.
Are you used to checking to see if the fan spins to verify if your power supply is working? No worries. AX1200i has a self-test switch to verify proper functionality before you install.

Compared to AX1200i, this PSU is about 10cm longer, so after installing all connectors you may face some cramped space in your PC case where PSU is located. Based on my experience, Corsair 900D case may run into this cramped space issue when you decide to install both 480mm AND 240mm radiators in the bottom chamber. In fact, you probably won't be able to fit 240mm radiator and this PSU on the same side because I struggled a bit when installing 240mm radiator and this PSU on the STH10 (it was tight, but I was able to get both components squeezed in while minimizing pressures on the connectors). So if I struggled with STH10, then my experience tells me that such an installation is not possible on Corsair 900D because the bottom chamber is smaller for this case when compared to that of STH10. But then again, this shouldn't be too much of a problem for people since the space issue can easily be resolved with smart build design modification. That being said, if you are building a PC anything less than a full ATX, no sli nor crossfire setup, maxed out RAM, extreme CPUs etc., you should probably go with other PSU models because this is clearly an overkill for anything less. My current build includes two R9 295X2. YES, TWO! And those who are aware, that VGA is power hungry. Yet, with this PSU there's still enough headroom. When my PC is on, the fan on the PSU does not even turn on. But the fan does kick in during heavy load, especially when gaming on 4k resolution and both VGAs are being fully utilized. Still, no shortage of power here.
My only problem is not directed at this PSU, but the option it provides. Specifically, the Corsair Link. Corsair really need to fix that God awful device or completely scrap the concept in its entirety. The software for Corsair Link is still unbearable to use and trying to get it to work properly is like pulling teeth. But to cover all basis, this PSU does allow the option to tap the Corsair Link functionality for monitoring power usage purposes. But I doubt most will connect this PSU to the Link especially since an alternative option is available - you can monitor either via Corsair Link or via internal USB which connects directly to your motherboard. I think most users will opt for the latter and the necessary USB connector is included. Strangely, Corsair did not include a Link adapter with this PSU, unlike AX1200i which does include the Link adapter and the connector.
Using the logging capabilities I plotted my unit's efficiency and included it here. You can see it matches their claim well. I attribute low wattage inefficencies to start up and shut down. Otherwise, my results match their spec's claim with 93% max efficency at 414 Watts.
The fan stays completly off at low heat, which is great. When it turns on it is very quiet.
Finally note that this power supply may be the largest wattage available in the smaller, "regular", form factor size. I cant fit the larger supplies with my radiator, so I luckily ended up with this power supply.
Pros:
High quality build, heavy duty parts.
Full watt spec on 12V rail.
High wattage for small form factor.
"i" series has unique data collection capabilities.
Quiet, cool, and efficent operation. Zero fan speeds at low heat.
Cons:
Expensive. Thats all I can think of. Rarely goes on sale or has special deals.
Edit - At this price point standard sleeved cables should be included.
This is a very top line consumer power supply with extra cpabilities. If you can justify the cost, you will probably be very happy with the supply. I am.

How about a unit that didn't randomly shut down? After all a Power Supply Unit's main job is to supply power. Technically it does do that, just not all the time. There is no consistency with the shut downs. It'll go for a week and then all of sudden shut down three times in one night. It does it as much surfing Amazon as it does playing a graphic intense game, so it's not the load. It'd be bad enough if this happened with a cheap unit, but this thing was expensive.
This is the first computer I built from the ground up. Everything was top notch equipment, except for maybe the motherboard and I thought at first that was the problem because the PSU passed the self-test. So I upgraded to a better motherboard. Everything worked fine for a week and I thought I had solved the problem. Then out of the blue - random shut downs again.
I bought a Thermaltake PSU at BestBuy that was $100 cheaper. That was a two months ago and not one shut down since. After my ordeal I did some more research and found that other people are having the same problem.
It was too late to return it to Amazon by the time I determined without a doubt that it was the PSU. I know I can send it to Corsair for repair or replacement and I'll eventually do that. I just hate to pay shipping to and from for repairs on a brand new top of the line PSU. Seriously, I'd throw it away if it wasn't so expensive.
Also, the Corsair Link software that came with it is not that great. Every time you open it - when you close it - it asks if you want to save the changes. It doesn't matter whether you made any changes or not. You have to press yes or no. It's just annoying. I contacted Corsair and they said that they are aware of it and will fix it with a future update. Also, the software reports some items inaccurate. It told me that one of my hard drives was over 400 degrees. That particular hard drive wasn't even running. I have it there for backups only.
I have other Corsair products that I really like. The C70 Case, 16GB Dominator Platinum RAM, 480GB SSD, (8) 120mm fans.
But the AX860i is a purchase I regret.
Top reviews from other countries
One note that this is overkill for 16GB, I7 Extremem edition,H100gt water cooler,gtx970,1Tb hard dsik,graphics card and 1080Hdmi tv.
This will work efficiently if at least 20% of wattage is used. That above configuration use only abot 100watts. So it is recommended to either put more peripherals or buy lower wattage PSU.
Thanks
Great service and quick shipment from the ITwares guys also.
