Corsair Announces New AX1200i Digital ATX Power Supply

By - Source: Tom's Hardware US | B 26 comments

Corsair has taken the AX1200 PSU to the next level with its introduction of the AX1200i Digital ATX PSU at Computex 2012.

The AX1200i builds upon Corsair's AX1200 modular power supply to reach 80 Plus Platinum certification. The AX1200i’s digitally-controlled power circuitry provides stable voltages, and low ripple and noise. In addition, the AX1200i offers high energy-efficiency of up to 92%. These features are aided by the reduced component count and redesigned circuit-board layout, which is made possible by the DSP-based design. The high efficiency results in reduced heat, which allows the AX1200i to operate in a silent fanless mode until the PSU load reaches 40% of the maximum power rating.





AX1200i’s DSP-based design, combined with Corsair Link technology, provides enthusiasts with control over the features and performance characteristics of their PSU. This allows users real-time monitoring of temperature, current draw, and power efficiency, as well as the ability to adjust the speed of the internal 140mm fan. In addition, the features give users the ability to switch from the default single +12V rail configuration to a tailored “multi-rail” mode, with the ability to set over current protection set-points on a per-rail basis. 

The AX1200i Digital ATX Power Supply will be available beginning in August, with pricing being announced upon product release. The AX1200i is backed by a limited 7-year warranty.

    I've had my AX1200 for about a year now, if I didn't already have one this is what I would be getting.
    Oh well I'm not disappointed, but I am a little intrigued by the "tweaking" you can do on this PSU.

    I understand how you feel, Corsair does many things right. This is one of the reasons I'm holding out on buying their HX power supplies right now since I've heard news saying that the HX series is getting an update as well, with the same price tag as the current model.

    I kinda feel sorry for those who decide to cheap out and buy those $20 1200W PSUs, and wonder why it failed and took out their entire computer (except for case, monitor, mouse and keyboard) when the load was under 600W.

    that is made by seasonic most likely. the fanless mode sounds just like hybrid fan technology

    I know a computer in my house that really wants this... Looking forward to this release.

    I was wondering when Flextronics was going to do another power supply for Corsair. Hopefully they do as good a job with this one as they did with the previous 1200AX. The real time monitoring function is pretty sweet. I would love to see it becoming standard on all quality power supplies.

    Too bad this is going to mostly be used in systems where people think they need 1200 watts with their HD 6870.

    f-14looks like a poor air flow design and ventilation, i don't see this PSU lasting longer than 3-5 years due to heat issues for those who would actually push this thing over 1000w


    Most PSUs look just like this when opened up. But the main thing here is lower operating temperature which means it will run cooler when pushed to 1000w compared to normal 1200w PSUs.

    Plus there is normally a plastic guide to help guide the air out, it wont be shown with the top part off.

    At my work, we use mainly Corsair PSUs for our builds and have only had a few come back bad for the hundreds we sell or use every year which is very good.

    Just had a guy bring in a 650TX in saying it was bad but all the voltages were near perfect (one was off by .1) and it powered on a test system just fine. Corsair PSUs are some of the best next to Seasonic.

    "This allows users real-time monitoring of temperature, current draw, and power efficiency, as well as the ability to adjust the speed of the internal 140mm fan."

    This sounds great and would be great to have. We can readily monitor stats of CPU, GPU, RAM and HDD, finally PSU gets some love too.

    Sensor monitoring from the computer is a great idea, but configuring the rails, not so much. If these things catch on, I would not be surprised if viruses took advantage of this functionality and say, lowered the current threshold to the point where the power supply cuts out if you try to run antivirus software.

    This is a pretty sweet PSU but in the days of the NVIDIA 670 and 680 using half the power that their predecessors did, is a 1200W PSU even needed anymore?

    Honestly, how often does a gaming rig exceed 480W of component power draw at idle? For instance, mine uses ~65W (80W from the wall), though it's not all that powerful compared to most (i5 750, single 550ti). I can definitely see this being fanless with most machines at idle.

    Nice features, able to see the efficiency and everything via software.

    Now that's a lot of power. For up to three power hungry computers lol.
