Cybenetics was formed with one purpose in mind; to introduce new efficiency and noise certification standards for AC-DC power supply units (PSUs) through its ETA and LAMBDA ratings. So far, we have certified over 660 units, and beta tested over a thousand, to help brands worldwide deliver better products. Besides PSUs, we have also enrolled in chassis noise testing, and there is another program currently in development, where besides power measurements, through our Powenetics solution, we also measure the overall noise output of graphics cards.

We are relentless, and we are always trying to come with new ideas that will help in the production of better products in every IT section. This is why we decided to make public our complete PSU test protocol, which besides the energy efficiency and output noise measurements, also explains the overall performance algorithm that we use in our beta testing program to provide as accurate as possible comparison data. This test protocol has been developed through many years of PSU evaluation experience. The methodologies in place, have been forged after numerous hours of testing and experimentation to obtain accuracy and reliability.Our PSU test protocol can be a great source of information to brands and manufacturers that want to check the compatibility of their products with our efficiency and noise standards (ETA and LAMBDA). Moreover, it will allow every laboratory with the proper equipment, to verify our results, as the ISO17025:2017 dictates. Finally, it will be an essential information source for interested users, wishing to dive deeper into PSU testing and learn more about this product, which is the heart of every system. All users can now discover the importance of various factors that form a PSU's overall performance.
