Corsair HX1200i: Reliable high-end power supply with strong performance
With the HX1200i (2025), Corsair updates the HX power supply lineup. Supporting the ATX 3.1 and PCIe 5.1 standards, special features such as an integrated connection for the 12V-2x6 connector with dedicated sense pins for an even safer power supply are included. With a total of 600 watts over a single cable, even the latest graphics cards are powered safely and efficiently.
Optimal cooling for long lifespan
The power supply is cooled by a 140 mm fan with a fluid dynamic bearing. Together with the switchable zero RPM mode, this results in an exceptionally long lifespan for the power supply, as the fan only activates at over 50% load. Additionally, high-quality components such as Japanese capacitors contribute to the safe and long-lasting power supply for your PC.
Excellent efficiency and software control
With 80 PLUS and Cybenetics Platinum certifications, the power supply from Corsair is particularly well positioned regarding efficiency. With up to 92% efficiency, the power supply guarantees efficient operation and, thanks to the special control of its components, a particularly quiet operation. The platform ensures stable power supply, thus minimising the phenomenon of coil whine.
To keep you fully informed at all times, the power supply is equipped with an additional USB-C connection. This opens up the possibility to monitor and adjust all voltages and the fan via software. All of this is made possible through the manufacturer's proprietary and well-known iCUE software. Thus, the power supply also serves as a perfect addition to your own iCUE ecosystem.
