  1. Do not take the test if you’re in a hurry.

    Some questions are worded weirdly, with lots of unnecessary words. Also, special cases are not considered (ie: PSUs with alternative inrush limiter approach like the Silverstone PTS series).

    Just read carefully and consider that a non native English speaker wrote this.

    Also, do not use the older ATX revisions as reference. Make sure you have the latest ATX v3 revision.

    Good luck

    1. Non-native English speaker: My pronunciation might not be the best, but my writing skills are in a whole different level so I don’t think that this applies.

      1. It does, but it is minor. There are just some idiosyncrasies in English and in Greek that do not play very well with each other.

        Note that I had to take the test twice to top it, cause of weird past experiences and not paying attention on some tricky questions, resulting in couple of errors on the first try.

        Apart from my personal opinion with the approach of the test going overboard on the technical terms, the test looks pretty much fine.

        Good work Aris!

    2. I did the test in a hurry, without Googling anything. I’m experienced 😀 So it can be done. 😉

      But I believe there was a mistake. Shouldn’t question two be PSU A with the 16AWG wires.

        1. Exacly!

          And question 21 is more like an opinion and not really a fact.

          In my opinion it’s agressive because the lowest fan speed is above 1000 RPM and it’s at 2000 RPM before full load.

          1. It is aggressive, the fan speed profile for the following reasons:
            It doesn’t increase linearly, from zero RPM goes to well over 1000 RPM without any intermediate stages
            At high loads, it is steady at full speed
