Digital control and monitoring

The Corsair AX1200i is a 1200 W fully modular ATX power supply that uses a DSP for real-time voltage regulation and Corsair Link software monitoring. It is built for high-end multi-GPU systems that need precise, software-controlled power delivery.

Platinum efficiency and voltage limits

The unit meets 80 PLUS PLATINUM certification with up to 92% efficiency across the 100–240 V input range. The single +12 V rail design and digital regulation keep output within tight tolerances defined by the ATX12V v2.31 and EPS 2.92 standards.

Full modular cabling and USB link

All cables detach so only required leads are installed, reducing clutter in cases that accept a 200 mm deep unit. The USB connection to a motherboard header enables Corsair Link monitoring; forgetting this cable or the software install is the most common reason telemetry appears missing.

Perguntas sobre este artigo

Which capacity in the AXi series should I pick for a multi-GPU build?

The AX1200i delivers 1200 W from a single +12 V rail and includes eight 6+2-pin PCIe connectors, so it can feed several high-end graphics cards without needing a second unit.

What does the 92 % efficiency figure mean once the unit is installed?

At typical loads the PSU converts at least 92 % of AC input into DC output, so less energy becomes heat and the 140 mm fan can run more quietly.

What digital interface does the AX1200i use and what does it control?

A USB link to the motherboard header lets Corsair Link software monitor voltages, fan speed and power draw in real time and adjust the fan profile.
