Aside from the voltage that power supplies can deliver at certain loads, it is also interesting to take a closer look at how stable that voltage is supplied. This is mainly important when overclocking, where even small fluctuations can impact the outcome in a negative way. In order to judge this we take a look at the ripple, where we measure the fluctuation of the voltage in millivolts.
Values smaller than 50 mVtt are excellent and values up to 70 mVtt are still fine. The good news is that all of the tested power supplies remain below 70 mVtt, and most of the power supplies even stay well below half that value.
