Complete Digital Control.
The revolutionary AX1200i is the first desktop PC power supply to use digital (DSP) control and Corsair Link 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, 80 PLUS Platinum Efficiency, and clean, stable power.
Real-time monitoring and control with Corsair Link
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 Link Commander (available separately). Then, download the free Corsair Link Dashboard software for unrivaled power supply monitoring and control options.
Monitor power input and output, efficiency, fan speed, and internal temperature, directly from the Windows based application. Or, take it to the next level and set up and modify fan speed profiles, or even select from virtual “single rail” or “multi-rail” software modes, with selectable OCP points.
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.

This is a premium priced PSU but the customer service is bargain bin. I paid a lot of money for a power supply that has been nothing but trouble since I got it not even 6 months ago. The web is littered with complaints on the AX series all with the exact same issues with many on their own forums. These PSU's should have been recalled, that much is clear. Now I'm now stuck with a lemon product and according to more complaints online there's not even a guarantee that a replacement will even resolve the issues. Just like a lot of other reviews my power supply constantly shuts off whenever if feels like it and gets stuck in a loop. Off and on, off and on. I've spent countless hours tearing down my PC and swapping parts (even spending more money on buying extra components to trouble shoot) only to have it happen again and again and again.
I just got off the phone with a customer service representative which took 3 calls and then almost 45 minutes of waiting to finally speak with an outsourced labor representative who had zero product information. Corsair offices close before I get off of work so I had to spend several of my lunch breaks just trying to get a hold of someone to help. When I finally do they tell me that the AX860i isn't even in stock! Are these units defective? Why don't you keep a stock? Is Corsair issuing a recall? These are questions I would like answers to but she had no knowledge, only apologies and three unacceptable options.
1. Call back next week and see if back they're in stock. Seeing as it took as long as it did to get through to someone that's not something I'm willing to do again. I need a replacement ASAP so "checking back in" is not an option.
2. Have Corsair order a replacement from Taiwan and wait for it. This is the person who is supposed to help me get an express RMA mind you.
3. Put up another $200 of my own money and order one online, wait for it to be delivered, return the defective power supply while paying return shipping out of pocket, then submit a ticket through Corsair and pray for a refund. I am most definitely not putting up any more of my own money only to have no leverage should Corsair decide not to pay out.
If this is Corsair's idea of customer service they've lost a loyal customer. I've been buying their products since the early 2000's. In my current build I have a case, a PSU, RAM and two SSD's. No company is perfect but this is just unacceptable.
I'm concerned with the high defect rate of the AX series and what Corsair is doing about them. Can they actually assure that the replacement PSU I'll receive will be problem free because looking on their forums all I see is their forum reps denying that there's an issue and instead blaming the customer. Corsair reps will tell you it's the motherboard as they won't take any responsibility or admit there's an issue with the AX series. They will also make you pay for return shipping of their faulty $200 product even though it's only a few months old. I've been pulling my hair out trying to fix this issue. I'm speaking with an attorney and looking to gather others together who've been affected. After looking at all of the reports of this same issue Corsair should have recalled this unit but instead they deny there's a problem. Go look on their own forum. It's filled with complaints of the EXACT same issue. This problem occurs in at least the AX760i, AX860i and AX1200i series PSU's. I imagine there's more. They will never get another dime from me.
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.
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.
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.
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.
