For the last seven or eight years, Corsair has released a boatload of power supplies, running the whole gamut of potential customers, since their initial HX620W release in 2006. Their current line-up is broken into eight distinct series. Some are modular, some are fully modular, and others are not. Several models hold the lowercase "i" suffix which signify USB connectivity to monitor and adjust the unit from their Corsair Link utility.
Today, Corsair is announcing the AX1500i fully modular power supply. At 1500 watts, this should be an effective upper limit on desktop power consumption. The real news is its efficiency: 94% efficient at half load on 115V input (North America). The PSU exceeds the specification set out for 80 PLUS Platinum and falls within the current draft of 80 PLUS Titanium (consumer).
It is also designed to be quiet and even fanless when drawing under 450 watts.
The suffix on the AX1500i signifies that it also integrates with Corsair Link through USB. Temperature, draw, loads, fan speed adjustments, and power efficiency are exposed to the user who wants to see a few more graphs in their secondary monitors… because if you have a single 1080p panel then you are doing something wrong somewhere.
The AX1500i is expected to retail for $449.99 in Q2 2014 and is backed by a 7-year warranty.

Corsair Announces AX1500i, the World’s Most Technologically Advanced and Efficient PSU for PC Enthusiasts
Corsair AX1500i DSP-based PC Power Supply Features Titanium Efficiency, and Corsair Link Monitoring and Customization
CES 2014 — Las Vegas, Nevada — January 7, 2014 — Corsair®, the most awarded PC power supply brand in the world1, today announced the AX1500i Digital ATX power supply. The PSU’s digitally-controlled circuitry delivers 1500 watts of ultra-stable power with efficiency that goes beyond 80 PLUSTM Platinum, making the AX1500i the most technologically advanced, energy efficient, and customizable power supply available for extreme PC enthusiasts. The AX1500i’s groundbreaking efficiency meets the current draft for ATX 115 Volt 80 PLUS Titanium for consumer PSUs.
The AX1500i's second generation digital architecture enables the PSU to consistently deliver up to 1500 watts of power with class-leading Titanium energy efficiency levels of up to 94%. The DSP-controlled circuitry of the PSU allows it to consistently deliver exceptionally stable voltages along with amazingly low ripple and noise. Tremendous power reserves combined with a vast array of cabling options enables the AX1500i to power heavily overclocked PC systems with up to four graphics cards in NVIDIA® SLI™ or AMD CrossFireX™ configurations with headroom to spare.
The AX1500’s leading performance is possible thanks to a streamlined component count and circuit-board layout made possible by the DSP-based design. The AX1500i’s high efficiency results in reduced heat, allowing the PSU to operate in silent Zero RPM Fan Mode until the load reaches 450 watts. A custom-designed fluid dynamic bearing 140mm fan, specifically designed for low-noise operation, allows the PSU to run quietly even when running at full 1500 watt power output.
"When we released the AX1200i, the world’s first digital ATX PSU, we defined the new standard for PSU performance, efficiency, and customization," said Aaron Neal, product manager of PSUs at Corsair. “Now with the AX1500i’s evolved digital architecture we’ve raised the bar again, creating the most efficient and technically advanced PSU available for the uncompromising PC enthusiast.”
AX1500i's DSP-based design, combined with Corsair Link™ technology, gives enthusiasts unprecedented control over the features and performance characteristics of their PSU. This includes real-time monitoring of temperature, current draw, and power efficiency, as well as the ability to adjust the speed of the internal 140mm fan. These features also allow for a unique level of customization, including the ability to set overcurrent protection points on a per-rail basis in the default multi-rail +12V configuration or simply switch to single +12V rail mode.
94% efficiency at 50% load at 115V
