Description¶
This driver implements the sysfs interface for the Corsair PSUs with a HID protocol interface of the HXi and RMi series. These power supplies provide access to a micro-controller with 2 attached temperature sensors, 1 fan rpm sensor, 4 sensors for volt levels, 4 sensors for power usage and 4 sensors for current levels and additional non-sensor information like uptimes.

Usage Notes¶
It is an USB HID device, so it is auto-detected and supports hot-swapping.
Flickering values in the rail voltage levels can be an indicator for a failing PSU. The driver also provides some additional useful values via debugfs, which do not fit into the hwmon class.

uptime |
Session uptime of the psu |
uptime_total |
