Features and Specifications

From Corsair:

Digitally-controlled power

State-of-the-art DSP-based power control technology providing outstanding DC voltage regulation, reliability and stability. 80 PLUS® Platinum Efficiency. DSP-control and Zero Voltage Switching and Zero Current Switching (ZVS / ZVC) technology results in up to 92% energy efficiency, resulting in lower energy bills, and less heat and noise.

Ultra Low Noise Design

Thanks to its high efficiency and low heat output the AX1200i is able to operate in a silent, fanless mode up to 30% of the rated wattage (360W), allowing for the possibility of fanless gaming. The fan speed ramps slowly above 30% load, so even fully-loaded PCs can be powered quietly.

Low Ripple and Noise: up to 3x better than the ATX Spec

Low ripple and noise equals high-quality power, allowing your performance-critical components, such as high-end graphics cards, to operate reliably for longer.

100.4 Amp Single +12V Rail

The AX1200i features a massive 100.4 Amp (1204.8 Watt) single +12V rail, making it the idea PSU for ultra-high end SLI and Crossfire gaming PCs based around multi-core CPUs.

Corsair LINK interface

Thanks to the DSP-based design, the AX1200i can be accessed using the Corsair Link interface. This server-inspired diagnostic tool can record and monitor real-time efficiency, power usage, and adjust fan profiles. Uniquely, the AX1200i can also be configured as a multi-rail device with individual PCI-E over-current protection (OCP) trip points.

Self Test Switch

The self test switch on the PSU confirms that all the DC output voltage rails are functioning correctly, and the fan is functional, providing a simple method of checking that the power supply is functioning correctly.

Fully Modular Cable System

The fully modular cable system provides total flexibility when building or upgrading your PC, since you use only the cables that you need. This reduced cable clutter also improves case airflow and cooling, and makes it much easier to build your high-end system and route cables.

Reliable

As with all AX PSUs, the AX1200i is built with premium components, such as high-temp 105C capacitors, and is capable of continuous power delivery at a temperature rating of 50° C, ensuring maximum performance and reliability even in the most hot-running performance PCs.

Protected

The AX1200i features a comprehensive array of protection and safety features. This includes Over-Voltage Protection (OVP), and Over-Current Protection (OCP) on the 12V, 5V, and 3.3V rails, Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP).

Warranty

The Corsair Professional Series AXi PSUs are backed by a 7-year warranty and customer support.

    These really are just about the best psu’s there are ATM. I own 2 of these.
    You can save some money by looking for sales, of course.
    With the entire included feature set, there really aren’t very many others to compare with these supplies. They’re simply the best.
