    Fanless is not under discussion here, only fan-off functionality (Zero RPM)

    That Tagan seems then first. Shame on me to have forgotten that. Their U01 models sold like crazy in Germany (until Liberty ).

    Wasn't that the first LLC-Resonant mode converter unit for Desktop Computers?
    Made by Etasis...
    Or was it the 450W version?
    Didn't it also have DC-DC??

    No, both ST30NF and ST45NF fanless PSU models didn't have DC-DC.
