For those shopping for a high-end desktop power supply for use under Linux and interested in being able to take advantage of sensor monitoring capabilities, the 2025 edition of the Corsair HX1200i PSU can now enjoy working sensor monitoring under Linux.
Developed back in 2020 was the corsair-psu open-source driver that allows for power supply monitoring under Linux for the company’s higher-end PSUs sporting the “Corsair LINK” USB-based interface. That driver was upstreamed back in Linux 5.11 and over time has seen new patches to support newer Corsair power supplies featuring this proprietary protocol. Now for Linux 6.17 the HX1200i (2025) power supply is the latest to be supported by this community-maintained, open-source driver.
Just a new USB device ID is needed for the 2025 model compared to the HX1200i legacy and 2023 series power supplies that were already supported by this Linux driver. Support for this latest Corsair HX1200i power supply was sent in via the HWMON updates for Linux 6.17.
This fully-modular, ultra-low-noise platinum 1200 Watt power supply with sensor monitoring doesn’t come cheap though. The Corsair HX1200i 2025 PSU has a list price of $355 USD.
Also worth mentioning with the Linux 6.17 HWMON code is the ASUS ProArt X870E-CREATOR WiFi motherboard being supported by the ASUS EC Sensors driver for desktop motherboard sensor monitoring.
