Final Thoughts and Conclusions

Corsair’s two new smart PSUs, the AX860i Digital and AX760i Digital, incorporate an imbedded DSP, which when used with the Corsair Link software allows the end user to monitor and adjust several power supply parameters like performance, noise (fan speed), and Over Current Protection (OCP) settings.  And many other Corsair products also support the Link technology (memory modules, case cooling fans and lighting subsystems, GPU Node for monitoring PCI-E current loads, etc.) so you can build a state-of-the-art, high-end gaming system with a built in DACS (Data Acquisition and Control System).

The Corsair AX860i Digital ATX power supply delivers very clean DC outputs, with excellent voltage regulation and efficiency.  Under light loads the AX860i runs in silent, fanless mode (up to ~30% load) and continues to be very quiet under normal operating conditions.  The AX860i Digital comes with a good assortment of all-modular cables that can support the latest CPUs and multiple, high-end video cards.  And let’s not forget Corsair’s 7-year warranty!

The MSRP for the four new Corsair power supplies are as follows:

AX860i $249.99 USD – $229
AX760i $229.99 USD – $209
AX860  $219.99 USD – $199
AX760  $199.99 USD – $179
