    This looks like a decent choice for a business-class PC, or even a light gamer, which probably won't pull more than half its rated output.

    Could you measure hold up at lower loads(20%, 50%, etc)?
    And why isn't inrush results included in cybenetics database?
    Normally "S" is considered higher than "A++"

    S stands for standard. As for the hold-up time, it is measured only in the worst case scenario, which is full load. Unfortunately there is no time to take extra measurements, especially since we want to implement some other tests.

    About the inrush current, Cyben''s pdf report covers only the basic in order to be kept at a normal size.

    Just curious how the values for hold up would look like at lower loads (I know it's higher). If you do plan on testing it even once at-least do it on a cheaper PSU unit. Testing it on a higher-end unit would defeat the purpose.

    And I thought Cybenetics was supposed to give a detailed report. Not including inrush results, etc kind of defeats the purpose.

    The main role of Cybenetics is to provide efficiency and noise certifications. The extra results are just to let people know a little more about a PSU's quality. If Cyben provided everything then it would be a review and not a certification.

    Quality,low power PSU's are hard to find-Reason-Quality components cost money.
    PSU IS THE MOST IMPORTANT PART OF ANY BUILD.....................

    Read the list of cons again. This thing is junk. There is no such thing as a decent $25 power supply.

    so more cons than pros, calling it decent build quality when almost all cons are related to quality.
    lol.
    less respect with every review like this..

    Every product is judged based on its price.

    "Almost all cons are related to quality". Actually two our of the six have to do, in a degree, with build quality. Thin cables and overated MOV. Transient response, lower hold-up time, noise and old platform are not build quality related. Build quality has to do with the quality of the components and the craftsmanship unless you imply/understand something else.

    You know what I also call decent build quality? A PSU that has a 25C rating and manages to finish all of my tests at much higher ambient temperatures. If its components were crappy then it wouldn't even last a minute under the overload tests, as many other PSUs that have died in my hands so far.

    cables are still components.
    and as well as everything else, it's still directly/indirectly related to quality, no matter if physical parts or design/engineering.
    especially since this isnt a box sold by a 12y living in the grandparents basement.

    i dont expect a semi modular unit with a 140mm silent fan on this, but i doubt lots of ppl would consider this type of "quality" product, if it was anything else they are using, not even talking about the fact its a name brand that sells very good units.


    when did it start to be ok for a product to have more cons than pros?...
    doesnt make any sense to me to call it "amazing value".
    but i guess thats just me.
