Summary of Key Features

Unique Design, Exclusive to Corsair
The Professional Series Gold AX1200 has been designed from the ground-up by Corsair’s power engineering team, and is therefore unique and exclusive to Corsair.

100.4 Amp Single +12V Rail
The AX1200’s massive 100.4 Amp (1204.8 Watt) single +12V rail makes it the ideal power supply for ultra-high end NVIDIA SLI™ and ATI CrossFireX™ gaming PCs based around multi-core CPUs.

80 Plus® Gold Efficiency
The sophisticated electrical design, incorporating advanced magnetic modeling during development in order to optimize magnetic component performance, delivers exceptionally high energy efficiency (90% and above). This meets or exceeds the requirements for 80 Plus Gold certification.

Outstanding Noise/Ripple and DC Voltage Regulation
The AX1200 features individual DC-DC regulation for 3.3V, 5V and 12V rails, and secondary side synchronous rectification, utilizing MOSFETs that have lower losses than the conventional output rectification schemes. An advanced 4-layer modular connector board PCB ensures a better ground return plane, lower resistance and low voltage drops. This, combined with circuit trace optimization, also helps to minimize ripple and noise.

Fully Modular Cable System
The fully-modular, low-profile cable system provides maximum flexibility when building or upgrading your PC, and maximum airflow through your chassis. This allows you to utilize only the cables that you need, reducing cable clutter and maximizing the cooling performance of your PC.

Zero Voltage Switching / Zero Current Switching Technology
The Corsair AX1200 utilizes ZVS / ZCS technology to switch at near 0V and 0A, which ensures there are minimal switching losses, thereby maximizing efficiency and further reducing waste heat.

Ultra Low Noise Design
The AX1200 utilizes a low-noise, thermally-controlled 140mm fan, and employs sophisticated techniques to enhance cooling performance and reduce noise. This includes a specially designed PCB that channels airflow to reduce back-pressure and maximize the fan’s cooling ability.

Summary
The Corsair Professional Series Gold AX1200 has been designed for one purpose alone — to be the best 1200 watt power supply on the market. By utilizing a server-grade powertrain architecture, incorporating ZVS / ZCS, independent DC-DC regulation, and premium quality components, the AX1200 delivers class-leading voltage stability and efficiency, and minimal ripple and noise*. A PCB designed using advanced fluid dynamics modeling, combined with efficiency levels of more than 90% at typical loads, means that the AX1200 generates minimal heat and noise levels. Taken as a whole, the Corsair Professional Series Gold AX1200 is the clear choice for enthusiasts who want the highest-quality power supply for their extreme gaming PCs and workstations.
