Know before you buy
The AX1600i uses advanced gallium nitride (GaN) transistors instead of traditional silicon. This allows for higher efficiency and better thermal performance, enabling it to exceed the requirements of the 80 PLUS Titanium certification.
Yes. By connecting the power supply to your motherboard via the included USB cable, you can use Corsair Link software to monitor efficiency, voltage, and power draw in real-time.
The Zero RPM mode is a feature that keeps the fan completely off during low to medium loads to ensure silent operation. The fan will only spin up once the power supply reaches a specific temperature or load threshold.
Absolutely. With 1600 watts of power and eight 6+2-pin PCIe connectors, it is fully compatible with both NVIDIA SLI and AMD CrossFire configurations, providing more than enough headroom for high-end multi-card builds.
Yes, being fully modular means you only attach the cables you actually need for your specific components. This significantly reduces cable clutter inside your case, improving both aesthetics and internal airflow.
The AX1600i is built with 100% 105°C-rated Japanese capacitors, which are widely considered the gold standard for long-term reliability and stable power delivery in demanding environments.
