Having crowned a new silent PSU king, it's prudent to point out that in a competition among the best in any category, whether Olympic athletes or high performance computer power supplies, the differences between first, second and third place (and even lower ranks) are often marginal. With swimmers, runners, and skiers, it's sometimes measured in hundredths of a second. Similarly with quiet, high performance PSUs, a number of Seasonic and Corsair models come within 1~2 dBA@1m of the Modu82+ 625's default acoustics, and their electrical performance is close enough to be considered identical. In practical usage, the noise advantage between this PSU and some of the other top ranked quiet models may not even be audible because of the masking effects of other louder noise sources, either in the computer or in the environment. The noise advantage will also be insignificant if you're going to run this (or any other) PSU above the "hinge" point of the noise/load curve; once this point is exceeded, the differences between the various top models becomes truly moot — basically they all get too loud to be called "silent".
