be quiet! Dark Power Pro 430 power supply
 

In the noise generated by all those who wish to grab a bite out of the expanding quiet computing pie, it often seems that the number of really quiet products hasn't grown that much. There's just a lot more "quiet" marketing BS to wade through. Thankfully, this "be quiet!" Dark Power Pro power supply is an addition to the genuinely quiet group. Alas, it's only for 240VAC!
