    There is no info on the equipment used to obtain those measurements (unless I failed to see it). My main question is which sound analyzer-mic combo was used, to measure down to 12 db(A)?

    Can't we just use rpm values from review and cybenetics's report for rpm-to-dB[A] estimation? https://www.cybenetics.com/code/pdf.php?id=M3b

    That's not the point. The problem with the review is that there isn't anything in there over his equipment. So all numbers, voltage regulation, efficiency and noise could be fake.

    I am not following your logic. What is stopping person (with listed equipment) from faking numbers in review?
    Let's say person A listed his/her equipment. So all numbers, voltage regulation, efficiency and noise could be fake. If person A want that.
    As for measurement uncertainty, it cannot be determined without calibration certificates. Equipment (no matter how expensive) can be out of spec.

    Yes it's still possible, but less likely. Especially if there are pictures taken from the setup.

    Listing the equipment also tells you a bit over the precision and quality of the equipment. Seeing numbers like this without knowing anything doesn't tell you much.

    To me it looks like a fake review. He made three reviews in total about power supplies. The first one was this Silverstone. In that review he posted that he doesn't have any equipment. But in the two other reviews, both from Seasonic, he is talking about his testing method without saying anything about it. He only posted the numbers without any context.

    Seasonic, 2x 8pin connectors on a 650W PSU?! SRYSLY?!
    And then only one 8pin connector on the PSU side.

    WHY; just WHY?!
    Do you want people with VEGA and co burn that connector?!

    If you do such things, use one non modular cable with at least 1mm² to the first connector...


    But this way it's not something one should ever recommend....

    The specs are wrong on Seasonic's site and the review, there are actually four PEG connnectors on both the 650W and 750W version. One modular cable and one non modular cable.

    If you don't mind wattage label difference and the language, there is a Seasonic Focus 750w (750FM) review in Vietnamese
