We have already tested the Corsair AX1200 power supply unit, which specifications are identical to those of the model we’re about to review today (with the exception of the 80 PLUS certification level, which is now Platinum instead of Gold). What’s so interesting about the AX1200i? The key feature of the recently released subseries of top-end PSUs from Corsair is the Corsair Link interface which supports real-time monitoring and configuring of PSU parameters.
That’s why our traditional PSU tests will today be complemented with a review of the PSU’s intellectual features which are denoted by the “i” in its model name. Let’s get started now.
The following article offers a detailed description of our testing methodology and equipment and a brief explanation of what the specified and tested parameters of power supplies mean: X-bit Labs Presents: Power Supply Units Testing Methodology. If you feel overwhelmed with the numbers and terms this review abounds in, refer to the Methodology.
You can also go to our Cases/PSU section to check out reviews of all other PSU models we have tested in our labs.
We will mark the actual power consumption of three system configurations (discussed in our article PC Power Consumption: How Many Watts Do We Need?) in the cross-load diagrams. This will help you see if the tested PSU can meet the requirements of a real-life PC.
Closer Look at Corsair AX1200i
Package and Accessories
This model differs somewhat in its box contents from its non-i relative. For obvious reasons we will be comparing it with the Corsair AX1200 throughout this review.
The packaging is the same size and shape, but the color scheme is different. Some elements are now painted red instead of gold.
The back of the box is now black to match the front. Its contents have changed a little. The brief PSU description has moved up and a description of the Corsair Link feature has been added. The efficiency and noise graphs are larger now but the list of available power connectors is missing.
The accessories include a user manual, fasteners, a pack of single-use cable straps, a mains cord, and a Corsair sticker.
There is also a velvet pouch for the PSU and a fabric bag for cables, so there’re quite a lot of accessories inside.
The sealed silvery pack you can spot in the photo with accessories contains a Corsair Link adapter (there’s dual-sided adhesive tape in the pack with fasteners that can be used to attach the adapter anywhere in the computer case). Its fixed cable goes into a USB 2.0 header on the mainboard. Then it is also connected to the PSU's communication port with an included cable.
The exterior styling of this model differs from the AX1200. It is closer to the TX650 model considering the difference in size and the modular design. The top panel is fastened with hex-head screws. The embossed lines on its surface merge into the fan grid.
Viewed from this perspective, the only difference of the AX1200i from the AX1200 is the small plaque with its model name.
The modular connector panel is the same as the AX1200’s except that there’s a 4-pin connector for Corsair Link (we’ll discuss this feature later on) and a self-diagnostic button with LED indicator (this feature helps you make sure that the PSU is operational prior to installing it into your computer).
