From the manufacturer

The best enthusiast PC power supply you can own.

AX1500i defines the state of the art for enthusiast-grade PC power supplies. It provides 1500 Watts of continuous, digitally-controlled power on 15 Amp circuits of 115V or higher, and 80 PLUS certification with an incredible 94% efficiency rating. Zero RPM Fan mode ensures silent operation at low and medium loads, and the fully modular, low profile cable set makes for easy installation and great-looking builds.

AX1500i
AX1500i

Provides 1500 Watts of reliable, continuous power for high-performance PCs

If you’re building ultra high-end performance systems or pushing world overclocking records, you know it when even 1200 Watts just isn’t enough. The AX1500i reliably delivers 1500 Watts of continuous – not peak – power on demand. And, you don’t need any special household wiring to make it happen… you’ll get 1500 Watts of clean, stable power on 15 Amp circuits of 115V or higher.

Digitally controlled power

The AX1500i is designed around a DSP for increased efficiency, tighter voltage regulation, and superior electrical specifications. The elegant, DSP-based design reduces internal component count and allows for better control of electrical ripple and noise.

80 PLUS Titanium

The AX1500i, simply put, approaches near-perfect efficiency like no other desktop PC power supply has ever done. Amazing efficiency has so many benefits not only does it lower your operating costs, but it generates less heat, too. And that means that there’s less cooling required.

AX1500i

Zero RPM Fan Mode

In fact, most of the time, no active cooling is required. The fan simply doesn’t spin. And when you’re pushing it hard, the thermally controlled fan adjusts its speed to match demand. The custom-designed fan is extra large, with a diameter of 140mm for low noise even at full load.

AX1500i

CORSAIR iCUE desktop monitoring and control

The AX1500i to a motherboard USB header with the included cable, and you can use CORSAIR iCUE to monitor power input, power output, efficiency, and internal temperature in real time. You can customize fan speed, and set up your AX1500i to operate as a single-rail or with multiple virtual rails.

AX1500i

Fully modular, low-profile cables

AX1500i is fully modular, which means that there are no permanently attached cables. This greatly simplifies installation and allows you to use only the cables you need, for a neater, cleaner build. This can improve performance: fewer extraneous cables in your system can reduce airflow obstruction.

AX1500i

Intelligent Control. Unlimited Possibilities.

CORSAIR iCUE provides in-depth PSU voltage and performance monitoring, as well as stunning system-wide RGB lighting synchronization.

    5 Stars
    Top of the line - costly, very high quality with bells and whistles.
    I have had this power supply, AX860i, for nearly 5 years. It has never let me down. I have it powering a system with two overclocked R9 290s, an overclocked i7 4790k, a water pump,8 fans, 2ssds, wifi card and of course mobo. The "i" series allows for unique and fun data collection not supported by nearly any other line of models. I never stressed the unit to hard. I stress test up to 800 Watts only so I have headrom. I wouldnt be afraid to push spec with this unit if I could.Using the logging capabilities I plotted my unit's efficiency and included it here. You can see it matches their claim well. I attribute low wattage inefficencies to start up and shut down. Otherwise, my results match their spec's claim with 93% max efficency at 414 Watts.The fan stays completly off at low heat, which is great. When it turns on it is very quiet.Finally note that this power supply may be the largest wattage available in the smaller, "regular", form factor size. I cant fit the larger supplies with my radiator, so I luckily ended up with this power supply.Pros:High quality build, heavy duty parts.Full watt spec on 12V rail.High wattage for small form factor."i" series has unique data collection capabilities.Quiet, cool, and efficent operation. Zero fan speeds at low heat.Cons:Expensive. Thats all I can think of. Rarely goes on sale or has special deals.Edit - At this price point standard sleeved cables should be included.This is a very top line consumer power supply with extra cpabilities. If you can justify the cost, you will probably be very happy with the supply. I am.
