This driver provides a sysfs interface for MSI PSUs with a HID monitoring interface.
Measurements for the output voltage and current for each rail are provided, as well as total output power, temperature, and fan control.
Additional properties are available in debugfs, such as an efficiency measurement, and switching to/from 12V mutli-rail mode
| curr1_input | Current on the 12v psu rail |
| curr2_input | Current on the 5v psu rail |
| curr3_input | Current on the 3.3v psu rail |
| fan1_input | RPM of psu fan |
| in0_input | Voltage of the psu ac input |
| in1_input | Voltage of the 12v psu rail |
| in2_input | Voltage of the 5v psu rail |
| in3_input | Voltage of the 3.3v psu rail |
| power1_input | Total power usage |
pwm1 |
PWM value for fan1. Writes to this file will switch set pwm1_enable to manual control mode |
pwm1_enable |
PWM mode for fan1. (2) means "auto", and uses the built-in fan curve. (1) means manual control |
| temp1_input | Temperature of the psu |
It is a USB HID device, so it is auto-detected, supports hot-swapping and several devices at once.
| multi_rail_enabled | Single or multi rail mode of the PCIe power connectors |
efficiency (ex: 8512 == 85.12%) |
An efficiency measurement, expressed as per-ten-thousand |
| product | Product name of the psu |
| revision | Revision number of the psu |
| uptime Session upti | me of the psu |
| uptime_total Total up | time of the psu |
| vendor Vendor name | of the psu |
