The Corsair AX1200i Digital ATX Power Supply is a revolutionary, high-performance power supply unit known for being one of the first to use a Digital Signal Processor (DSP) for enhanced monitoring and control via Corsair Link or iCUE software.It offers a massive 1200 watts of power with 80 Plus Platinum efficiency, ensuring stable, clean power delivery for high-end gaming or multi-GPU systems.The fully modular design and quiet, thermally-controlled fan operation make it a premium choice for enthusiasts seeking both performance and customization.

The core innovation of the Corsair AX1200i lies in its use of a Digital Signal Processor (DSP), which replaces traditional analog controllers for real-time adjustments and incredibly tight voltage regulation, leading to exceptional system stability.This digital control, combined with Corsair Link (or the more modern iCUE) software integration, provides users with an unprecedented level of control and monitoring.Through a simple USB connection to the motherboard, users can monitor power input/output, efficiency, fan speed, and internal temperature directly from a Windows application.The software also allows for the configuration of fan speed profiles and even toggling between virtual "single rail" and "multi-rail" Over-Current Protection (OCP) modes, catering to diverse system build preferences and safety requirements.

The AX1200i excels in power efficiency, achieving an 80 Plus Platinum certification, which translates to minimal wasted power and reduced heat generation.This high efficiency enables a silent, fanless operation mode at low to moderate loads (up to around 30-40% of maximum power), making it an ideal choice for a quiet PC build.The unit is built with high-quality components, including high-temperature Japanese capacitors, to ensure uncompromised performance and long-term reliability, a claim backed by a generous 7 to 10-year warranty.Its fully modular, low-profile cable system further enhances installation flexibility and airflow within the PC chassis, contributing to a clean and efficient system build.
