A little over a year ago, we took an in depth look at Corsair's AX1200. The unit proved to be quite the beast. It was packed with just about all the features you could think of at the time including a full set of modular connections, 80Plus Gold certification, near silent cooling and a ton of power. On top of that, it performed almost flawlessly. We even sent the unit over to our very own Chad Sebring for some testing of his own in his highly overclocked system. He was able to pull several hundred more MHz out of his processor and a tad bit more on the video cards. We simply couldn't recommend the unit enough, but there was always one question that loomed in the back of our heads: "Where will Corsair go from here? They have to beat it somehow don't they?"
Fast forward to now and Corsair has answered our questions. They have used the original AX1200 and improved upon it in just about every way by bringing us the AX1200i. Many are thinking that since the unit already performed so well that the only thing we are talking about are minor improvements all the way around with efficiency, DC output quality and voltage regulation.
Corsair promises all of those are in fact improved, but there is more than that to the AX1200i. Corsair has also managed to work in the Corsair Link hardware and software with the AX1200i to give you the ability to monitor the entire power supply and even do some custom configuration to how the unit performs. Can these improvements really make that much of a difference and will the integration with Corsair Link be that beneficial?
Let's dig into the unit and find out just what these changes mean and how well the new model performs.
Specifications, Availability and Pricing
DC output has remained unchanged from the previous AX1200 power supply. Both of the minor rails are rated for 30A each with a combined maximum output of 180W. The single 12V rail is rated for 100.4A or a total of 1204.8W, which is the entire output of the power supply. Through the use of the Corsair Link software, you can configure the power supply to essentially treat each PCI-E connector as its own rail. The 24-pin Main and all peripheral connectors are excluded from this. Corsair also supplies the AX1200i with slightly beefed up 5VSB rail rated for 3.5A over the typical 3.0A we find on most units.
As far as features go, you're going to be very hard pressed to find anything that has more than what the AX1200i offers. Not only does it score a check everywhere on our list above, but it also has the DSP and Corsair Link integration. Not only does it have the protections including over current protection, but once you enable the multi-rail mode within the Corsair Link software, you can actually set the specific OCP point that you want on each rail, up to 40A. These features combined make this the most advanced power supply to ever make it in the hands of consumers.
Corsair is launching the new AX1200i with an MSRP of $350. That is about $50 more than what the original AX1200 retailed for and is a fairly reasonable increase considering that you're getting increased features and efficiency. Newegg currently has the power supply in stock at MSRP and tack on a $5.99 shipping fee. The AX1200i is backed by Corsair's amazing seven year warranty.
