Corsair 1500 Watt AX1500i is now qualified for 80 Plus Titanium efficiency rating which obviously is better than 80 Plus Platinum. It offers 91.23% efficiency at 10% load, 92.63% efficiency at 20% load, 94.04% efficiency at 50% load, and 91.34% efficiency at 100% load, staying above 90% at all test scenarios. The PSU’s digitally-controlled circuitry delivers 1500 watts of ultra-stable power with efficiency that goes beyond 80 PLUS 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 fully modular PSU offers a boat-load of power connectors, and should drive R9 290X 4-way CrossFireX setups with 220W TDP FX-9590 CPUs.
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.
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.
