Dear maintainers,

I tried to test a different PSU in my system and noticed some instabilities in Linux&hardware operation with it.
I looked into "sensors" printout and found there are no +5V and +12V levels reported.
In UEFI BIOS HW monitoring section I clearly see +12.01..+12.04V and +4.92..+4.96V but don't see them from the running Linux.
"sensors-detect" propose that I load "coretemp" and "nct6775" modules without parameters, which I made to be loaded on boot.
"sensors" shows adapters nct6791-isa-0290 with lots of voltages, temps and fan speeds, acpitz-acpi-0 with 2 temps around +27..29°C, and coretemp-isa-0000 with 1 package temp. and 2 core temps, all around +34..36°C
From some directions I found on the Internet, people recommend explicit configuration of in1 and in4 inputs for nct6791-isa-0290 which are supposed to report +5V and +12V for this chip but I am not sure I could do this by myself without interaction with someone more experienced.
I looked into text files under /sys/devices/platform/nct6775* but for in1 and in4 _input values I found only integer number 1024 which does not look like a real measurement.

Please if possible help me to resolve this problem. Thank you in advance.
