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.
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.
