Design & Build Quality
Both PSUs feature a durable matte-black chassis, fully modular cables, and premium Japanese capacitors rated for long-term stability.
The HX1200i, however, refines internal layout efficiency and fan management slightly—resulting in better thermal performance and reduced electrical noise under load. Both are ATX form factor and compatible with most modern mid-tower and full-tower cases.
Noise and Cooling Performance
Corsair’s Zero RPM Fan Mode ensures near-silent operation under light to moderate loads on both models. The HX1200i has a small edge thanks to its 140mm fan and digitally controlled fan curve, which optimizes cooling more smoothly than the HX1200’s mechanical control.
In stress tests, both stay impressively quiet, but the HX1200i remains slightly cooler under heavy GPU or CPU loads.
Efficiency and Performance
Both power supplies boast 80 Plus Platinum certification, guaranteeing up to 92% efficiency at 50% load. Power delivery is extremely stable, with tight voltage regulation and minimal ripple noise — ideal for high-end CPUs and GPUs.
The HX1200i can track these performance metrics in real-time through Corsair iCUE software, giving advanced users data on power draw, efficiency, and internal temperature.
Key Takeaways
When comparing the Corsair HX1200 vs HX1200i, a few critical distinctions emerge that could sway your purchasing decision.
- iCUE Integration: The most significant difference is the ‘i’ in HX1200i, signifying its compatibility with Corsair’s iCUE software. This allows for real-time monitoring of power input/output, efficiency, fan speed, and even the ability to switch between single and multi-rail OCP (Over-Current Protection) modes digitally.
- Physical Size: The HX1200i is slightly longer (200mm vs 180mm for the HX1200), which might be a factor for smaller PC cases.
- Fan Size: The HX1200i features a larger 140mm fan compared to the HX1200’s 135mm fan. While both are FDB and feature Zero RPM mode, the larger fan could potentially operate at lower RPMs for the same airflow, leading to quieter operation when the fan is active.
- Rail Configuration: While both offer single and multi-rail options, the HX1200 uses a physical switch, whereas the HX1200i leverages iCUE for more granular control.
- Both PSUs deliver top-tier stability, efficiency, and silence.
- The HX1200i adds digital controls and live monitoring via iCUE.
- The HX1200 remains the simpler, value-focused option with identical performance.
- Both come with a 10-year warranty, reflecting Corsair’s confidence in durability.
