techPowerUp posted a review on the Corsair AX760i 760 W PSU

We tested Corsair's flagship PSU, the AX1200i, in the past and were amazed by its overall performance and the features it packed. It was the first Platinum Corsair PSU and the first desktop PSU that used digital (DSP) control to provide the best possible voltage regulation, extra-low ripple, and sky-high efficiency. The AX1200i costs a significant amount of money, and most users don't need a 1.2 kW monster for their system which meant that Corsair had to find a way to bring the cutting-edge technology this unit utilizes to more affordable and smaller capacity units. Thankfully, Corsair managed to accomplish this task by packing all the exotic features of the AX1200i into their new AX860i and AX760i PSUs. Both of the aforementioned PSUs feature DSP control and can be connected to USB headers on the mainboard (or to a Corsair Link Commander that must be bought separately) through a provided cable that allows the user to monitor and control many of the PSU's functions through the Corsair Link software.

The only other desktop PSU to utilize DSP control is EVGA's SuperNOVA NEX1500 Classified 1500 W unit. It, however, only provides digital control for the +12V rail, while the Corsair AXi PSUs control all three major rails through DSP. This is a major difference since a complex digital circuit, which surely affects production costs, is required to control all three rails.
