Digitally Controlled Power

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.

The built-in Corsair Link™ functionality allows you to know how well your AX1200i is working 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.

- Digital Signal Processor (DSP) for delivering extremely clean, efficient power with real-time adjustments.
- Corsair Link. Integration for monitoring and adjustment of performance, noise, and OCP settings.
- 80 PLUS Platinum Efficiency for lower power usage and energy costs.
- Fanless operation at low loads, for outstanding noise reduiction.
- 140mm thermally controlled double-ball bearing fan spins up as needed.
- Fully Modular low profile cables for easy installation and less clutter.
- Engineered to meet maximum power output at a server-grade 50C temperature rating.
- Self-test switch to determine PSU functionality even before installation.

Question  HAF 922 Compatibility. by Jianni


would this psu fit in the HAF 922 Case?
I have tried searching around but had no luck.

This is compatible yes. Bit of a squeeze though. Best going for the HAF X instead if you are sticking with the CM HAF range.

Thank you.
