Corsair AX1200i 1200W Power Supply Review

Corsair AX1200i Gets Reviewed

Lately, 80Plus Platinum certified
power supplies have been springing up like wildflowers. Every enthusiast was
certain that Corsair, being one of the major players in the high performance
PSU market at this point of time, would not sit this one out. Truly, Corsair
today released the AX1200i, an 80Plus Platinum certified power supply with a
maximum power output of 1200W. However, the AX1200i is quite a bit more than
“just another power supply”, as it also comes with never seen before
features and capabilities which will certainly trouble the competition and
charm hardcore enthusiasts.

Even though the new AX1200i is based
on the platform used to create the AX1200, Corsair heavily upgraded the base
design and added DSP control via their Corsair Link interface. The interface
allows the end user to not only monitor the power supply’s performance through
a windows based application (Windows 7 only support, sorry Linux/MAC users) in
real time but to also control certain aspects of the AX1200i, such as the
behavior of its fan, the OCP protection levels, etc. The software also monitors
temperatures and fan speeds of other devices it can recognize, such as the
drives and the CPU, plus it offers the capability to create graphs, profiles
and other fancy features which crazed tuners will surely appreciate. Note however that the software is still BETA; there are many bugs which need to be ironed out.

The DSP control alone would not be
enough to please every enthusiast and Corsair knows that; however, the AX1200i
also promises unparalleled performance and high aesthetic value. On the other
hand, the MSRP of the AX1200i is $349.99, making it one of the most expensive
units currently available. Although the retail price will most certainly be
somewhat lower, it would still be a massively expensive product. So, the
question is, does the AX1200i really perform that well so as to justify the
premium price? We will find out in this review.
