We review the Corsair Professional Series AX1200i PSU. The 1200W PSU is massive in performance, the one massive 100A 12-volts says it all really. Excellent for multi-GPU solutions and hardcore overclockers. Corsair also embeds their LINK technology into the PSU. That means you can monitor the PSU with the help of software, things like PSU efficiency, power usage or simply to adjust the fan RPM. We'll show you that in the review though.
