Corsair AX 1200I - The First Digitally-Controlled PSU

10/8/2012 3:17:38 AM

With the AX1200i, Corsair brings the power supply into the digital age, as it’s the first digitally-controlled PSU. What does the digital control mean for our build? The integration with Corsair Link technology provided us with the ability modify fan speed profiles and switch the power supply between virtual “single rail” to “multi rail” power modes. For each rail, we can even select individual overcurrent protection settings.

Description: AX1200I


A Link To The Future

Through the Corsair Link Dashboard, we have access to a number of configuration capabilities. We were able to see the real­ time power input and output, efficiency level, fan speed, and internal temperature. When temps started creeping up, we were able to simply bump up the fan speed. Of course, we were also able to set the temperatures at which the fan speeds automatically increase, so the AX1200i could adjust to the power needs of our 3D gaming rig across various applications.

Some other key benefits of the DSP (Digital Signal Processor) include improved efficiency, more stable power delivery, and automatic adjustment in voltage regulation. The ability of the Corsair AX1200i to digitally control voltage helps to deliver clean, reliable energy to the hardware inside our system, because it can make on-the-fly changes based on the settings we configured in the Corsair Link Dashboard.

Efficiency & Heat

The AX1200i meets the 80 PLUS Platinum certification and can reach a maximum efficiency of 94%. Another way that Corsair helps increase efficiency is through the use of a thermally-controlled fan that doesn’t spin until the power supply goes beyond a 30% power load. The silent design helped to reduce the ambient noise level of our PC. The fully modular AX1200i also helped to improve airflow inside the system, because we only needed to install the cables necessary to power our hardware.

Ready For Anything, Anytime

There are six +12V PCI-e 6 + 2-pin connectors to support triple SLI and Cross Fire builds, and motherboards with overclocking features are covered through the two 8-pin EPS connectors.

You’ll also find 16 SATA, 12 Molex, and two floppy connectors. Thanks to its ready expandability, considerable power, and tightly controlled efficiency, the high-tech AX1200i is likely to be the last power supply you’ll need to buy for quite some time. And because Corsair backs it with an impressive 7-year warranty, you can rest assured that it will be ready to go every time you need it.
