PSD with dB ON: is it 10*log(x) or log(x) ?

The Power Spectral Density (PSD) in LabView has an option of outputing dB values. I have found that it do this: 10*log(x). I just want to confirm that this is the case in all versions of LabView (I have 8.6) because If I am to use that program in different system I do not want different outputs that may be confusing.
