Introduction and Features

Corsair announced their latest flagship power supply, the 1,500 watt AX1500i Digital ATX PSU earlier this year at CES. We recently received a retail unit to review and have spent the past week putting it through our suite of tests. The new AX1500i Digital proved to be a very interesting power supply and brings not one, but several outstanding features to the high-end enthusiast market. Over time, we all grow numb to marketing terms like “most technologically advanced”, “state-of-the-art”, “ultra-stable”, “super-high efficiency”, etc., but in the case of the AX1500i Digital PSU, we have seen these claims come to life before our eyes.

Right out of the box, the AX1500i Digital power supply is capable of delivering up to 1,500 watts of continuous DC power (125 Amps on the +12V rail). If that is not impressive enough, the PSU can do it while operating on 115 VAC mains and with an ambient temperature up to 50°C (internal case temperature). This beast was made for multiple power-hungry graphic adapters and overclocked CPUs.

The Corsair AX1500i is one of the very first power supplies to obtain 80 Plus Titanium certification, which requires a PSU to operate with at least 90% efficiency between 10% and 100% load, and with at least 94% efficiency at 50% load.

The AX1500i is a digital power supply, which offers two distinct advantages. First, the AX1500i incorporates a Digital Signal Processor (DSP) to provide digitally-controlled power. This enables the PSU to deliver extremely tight voltage regulation over a wide range of loads. And second, the AX1500i features Corsair Link, which enables the PSU to be connected to the PC’s motherboard (via USB) for real-time monitoring (efficiency and power usage) and control (over-current protection and fan speed profiles).

Silent operation (zero-rpm fan mode up to ~30% load) might not be at the top of your feature list when shopping for a 1,500 watt PSU, but the AX1500i can do it thanks to high efficiency.

As promised, Corsair recently added four new power supplies to their AX Series including two new digital models, the AX860i and AX760i. The AX860i and AX760i PSUs bring most of the great features of Corsair's flagship AX1200i Digital ATX PSU (DSP control, Platinum efficiency, all-modular cables, and 7-year warranty) to PC gamers and enthusiasts who don't need a 1200W PSU and are looking in the range of 760 and 860 watts.  Both the AX860i and AX760i incorporate Digital Signal Processing to deliver extremely tight voltage regulation, clean and efficient power with the ability to make real-time adjustments to various internal parameters.  The included Corsair Link software can be used to monitor and adjust performance, noise (fan speed), and Over Current Protection (OCP) settings.  The Corsair AX860i and AX760i Digital ATX power supplies have been certified 80Plus Platinum for efficiency and come with all modular cables. 

In addition to the two new digital power supplies, Corsair is also revamping the traditional analog AX Series line with the addition of the AX860 and AX760 models, which include 80 PLUS Platinum certification, all-modular cables, and significantly lower noise levels than previous models.

The second coming of the AX1200, now with software controls

Corsair's new AX1200i PSU is 80 Plus Platinum rated and sports Link monitoring and control software as you might remember from Lee's review.  On the off chance that you would like a second opinion about the PSU, [H]ard|OCP recently published their own review.  Just like Lee they were impressed with the voltage regulation, efficiency, and DC Output quality though they were less impressed with the noise they saw during their Transient Load Test.  They also questioned the use of the Link tweaking software and while the final verdict was positive in some ways they didn't feel this PSU was as true successor to the stellar AX1200 released almost two years ago.

"Corsair has a refresh today that talks to its high end line of high power PSUs. The AX1200i comes in touting "platinum" efficiency and "an unprecedented level of monitoring and performance customization." How does the AX1200i perform out-of-the-box and does it actually bring value at its huge price?"

Here are some more Cases & Cooling reviews from around the web:

Here is what Corsair has to say about their new AX1200i Digital ATX power supply unit:  "The revolutionary AX1200i is the first desktop PC power supply to use digital (DSP) control and Corsair Link to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX1200i makes on-the-fly adjustments for incredibly tight voltage regulation, 80 PLUS Platinum efficiency, and clean, stable power.

Real-time monitoring and control with Corsair Link. Put the AX1200i under your control by connecting it directly to a USB header on your motherboard with the included cable, or to a Corsair Commander (available separately). Then, download the free Corsair Link Dashboard software for unrivaled power supply monitoring and control options.

Monitor power input and output, efficiency, fan speed, and internal temperature, directly from the Windows based application. Or, take it to the next level and set up and modify fan speed profiles, or even select from virtual “single rail” or “multi-rail” software modes, with selectable OCP points. "
