I bought a used motherboard on Aliexpress, the board has a low voltage of 3.3v in the bios. Could it be a problem with the sensor or some voltage regulator?
In the Hw Info one of the 3.3v is good, the other is identical to the bios around 2.8V.
It's not a problem with the power supply because on my Crosshair Vi Hero X370 the same power supply and the voltages are normal.
With the help of HWInfo, is it possible to know if it is a reading error in the sensor or a problem with the voltage regulator?

With the images it is possible to see that only on the X570 the 3.3v is low, this discards the power supply.
