Corsair AX1600i 1600W 80 Plus Titanium Digital ATX PSU

The Corsair AX1600i is a 1600W fully modular digital ATX power supply unit built on a resonant LLC topology with a synchronous rectifier design, achieving 80 Plus Titanium efficiency certification — the highest tier available — with up to 94% efficiency under typical load conditions. Constructed around a digital control architecture using a Texas Instruments digital signal processor, the AX1600i delivers precise real-time regulation across all output rails, enabling tighter voltage tolerances than analog designs. The unit connects natively to Corsair's iCUE software ecosystem via a built-in USB interface, exposing live telemetry including input and output wattage, individual rail voltages and currents, fan RPM, and unit temperature — data essential for monitoring high-draw professional workstations.

Designed to sustain continuous output at its full 1600W rating across all operating temperatures up to 50°C ambient, the AX1600i is engineered for workloads that simultaneously stress CPU, GPU, and storage subsystems at extended duty cycles. Its single +12V rail design simplifies load balancing for multi-GPU configurations and high-core-count processors, while the dual EPS12V connectors and multiple PCIe power leads accommodate HEDT platforms. The zero-RPM fan mode keeps the unit silent under light loads, with the 140mm magnetic levitation bearing fan activating only when thermal conditions require active cooling.

The fully modular cabling system eliminates unused cable clutter within chassis, supporting clean airflow management in rack-adjacent tower workstations and high-density editing suites. With over-voltage, over-current, over-power, short-circuit, over-temperature, and under-voltage protections implemented across all rails, the AX1600i provides a protective foundation for critical professional hardware assets. Its sustained relevance as a flagship reference-class unit reflects the durability of the underlying platform for long-term enterprise workstation deployments.

Ideal for

• Powering multi-GPU deep learning workstations requiring sustained 1400W+ combined CPU and GPU draw during extended training runs
• Supporting HEDT platforms such as AMD Threadripper or Intel Xeon W with dual EPS12V requirements alongside high-end professional graphics cards
• Enabling iCUE-integrated power telemetry monitoring across a fleet of high-performance content creation workstations for facilities management
• Providing stable, high-efficiency power to professional 3D rendering nodes where continuous full-load operation demands Titanium-class efficiency to reduce heat output and operating overhead
• Serving as the primary PSU in broadcast or post-production editing suites where zero-RPM silent operation under moderate loads is operationally critical
• Supplying reliable, protection-rich power to irreplaceable scientific computing workstations where rail stability and comprehensive fault protection are non-negotiable requirements
