Anantech, one of the biggest PC hardware sites around, has taken a page from SPCR and provided noise measurements on a roundup review of 4 PSUs. They're mostly loud models. Voltage regulation is examined but there is no power load testing nor any indication of efficiency. And while the noise measurements are useful for comparison, they don't tell you the noise levels at min vs. max load. Plus they add to misformation about noise by saying things like a device that is 3dBA louder than another is approximately twice as loud. Jeez! You think they'd know better!
