Bigbruin.com posted a review on the Seasonic S12D 750W Power Supply

After many hours of testing, the Seasonic S12D 750W power supply proved itself to be a pretty solid unit. It even bested a popular 80 Plus certified PC Power & Cooling brand unit rated for the same total power. Among other things, the S12D 750W is solidly built, very quiet under load, and considerably smaller than its PC Power & Cooling counterpart.
