P R O F E S S I O N A L S E R I E S™ P R O F E S S I O N A L S E R I E S™ Congratulations on the purchase of your new Corsair Professional Series AX1200i digital ATX power supply. The Corsair AX1200i is a groundbreaking new design. It is a departure from traditional PSU designs and is packed with features that will make building your ultimate dream PC even more enjoyable. The AX1200i introduces some new and exciting technologies, so please read below for more information. ensuring tight DC output voltage regulation without the ripple/noise, transient response, and converter stability drawbacks associated with conventional power supply designs.

Low DC Output Voltage Ripple and Noise The AX1200i 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 and advanced filtering techniques, helps to minimize ripple and noise.

Reduced Component Count and Increased Reliability The digital control of the AX1200i eliminates many external components required by more conventional PSU solutions to offer an extremely small, high density, high reliability solution that allows incremental space to add extra features - like real time parameter monitoring and power supply control. Product Features Digitally Controlled Power Unlike traditional power supply designs, the Corsair AX1200i uses a Digital Signal Processor (DSP) for optimized efficiency and tighter voltage regulation, which improves overall system stability and component reliability. Quiet, Efficient Operation Upgrading to digital provides increased efficiency. The AX1200i is certified 80 PLUS® Platinum, which results in lower heat generation and a quieter fan profile. The AX1200i is so efficient that the 140mm fan doesn’t even spin at low loads for completely noiseless power delivery. Corsair Link™

User Friendly Features

The built-in Corsair Link™ functionality shows you how your AX1200i is performing at any given moment and lets you quickly tweak its performance. Server-inspired diagnostic tools monitor real-time efficiency, power usage, configurable over-current protection points and fan profiles. Brilliant Design

Ultra Low Noise Design The AX1200i 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 cooling effect of the airflow. The fan remains off under light load conditions and can be controlled via a graphical user interface.

Self Test Switch The power supply can be validated prior to system installation via a self test switch, which confirms all DC output voltage rails are present and the fan is functional. The fully modular cables make it easy to install and the self-test switch lets you quickly determine if the AX1200i is functioning normally before you even attach cables to your motherboard. Technology and Benefits

Digital Control The AX1200i Digital ATX Power Supply features an advanced control architecture to produce outstanding dynamic response. It features a true digital engine that provides superior on-the-fly performance optimization across the full operating range while maintaining stable operation.

80 PLUS® Platinum Efficiency The sophisticated electrical design, incorporating advanced hybrid digital control and state of the art magnetics delivers extremely high energy efficiency (92% and above).

User-Selectable Over-Current Protection The AX1200i has a massive 100.4 Amp (1204.8 Watt) single +12V rail, which makes it the ideal power supply for ultra-high end multi-GPU systems based around powerhungry CPUs. If you prefer multi-rail architecture, the PCI-E Over-Current Protection trip points can be configured individually via the Corsair Link™ Dashboard software. Outstanding DC Voltage Regulation Due to its digital design, the AX1200i delivers exceptionally stable power over the whole load range and automatically compensates for DC output cable voltage drop, 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. Safety and Protection

Over-Voltage Protection (OVP) Over-voltage protection for the 12V, 5V and 3.3V DC outputs is required to comply with the ATX specification. OVP shuts down the PSU in the event that the DC outputs exceed a set level, determined by the PSU manufacturer. The minimum voltage levels required for compliance are 13.4V for the +12V rail(s), 5.74V for the +5V rail and 3.76V for the 3.3V rail.

Over-Current Protection (OCP) The AX1200i features OCP on the 3.3V, 5V and 12V rails. OCP ensures that the output of the DC voltage rails remains within safe operating limits. The AX1200i can be configured as a single rail or multi-rail OCP solution.

P R O F E S S I O N A L S E R I E S™

P R O F E S S I O N A L S E R I E S™ Over-Temperature Protection (OTP) OTP ensures that the PSU will shut down when the internal temperature reaches a set point. This is usually as a result of internal current overloading or a fan failure. Short-Circuit Protection (SCP) A short-circuit is defined as any output impedance of less than 0.1 ohms. Amongst other things, SCP ensures that the PSU shuts down should the 3.3V, 5V and 12V rails short to any other rail, or to ground. It also ensures that no damage should occur to the unit, or your PC’s components, in the event of a short. Power Supply Specifications

P R O F E S S I O N A L S E R I E S™ P R O F E S S I O N A L S E R I E S™ Using the Self Test Feature

SELF TEST In order to use the self-test feature, please follow the steps below.

1. Connect the PSU to an AC power source, and flip the power indicator on the

back of the PSU to the On position (I).

2. Press the self-test button on the modular connector side of the PSU.

3. If the button lights up green and the fan spins for a moment, you’re good to go!

4. If the button lights up red or does not light up at all, please contact Corsair

COMM PORT customer service for further technical support. Connect the SATA cables to your SATA SSD or hard drive’s power sockets. SELF TEST Connect the PCI-Express cables to the power sockets of your PCI-Express video cards if required. d. Connect the peripheral cables to any peripherals requiring a small 4-pin connector. e. Make sure all the cables are tightly connected. Connect the AC power cord to the power supply and turn it on by pushing the switch to the ON position (marked with “I”). SELF TEST Using Corsair Link™ with your New AX1200i COMM PORT Before you are able to monitor your new PSU with Corsair Link™ you must connect the power supply to an internal USB header using the Digital Interface Cable and USB Dongle.
