"The Cooler Master Silent Pro Gold 1200W  power supply produced a mixed bag of results during testing. The DC  voltage load  regulation was excellent and on a par with other power supplies in this  class,  but it did produce a disappointing set of results for AC noise/ripple. I  always  measure the AC noise/ripple levels at or near full DC load, which will  always  produce worst case results, but this is the recommended method as per  the ATX12V  V2.2 specification and the Cooler Master Silent Pro Gold 1200W doesn't  perform  too well."
