while the Silencer 610 is a great PSU, they are hardly quiet if you are really after a 'quiet' or 'silent' PC. If you want something that is highly stable and powerful, that doesn't make a lot of noise then go for it!
The Silencer 610 is made by Seasonic, so by default it's kinda on the recommended list anyway. But, with only a single 80mm fan it's considerably louder than the older Seasonic S12 series, which have been replaced by the newer and quieter version. Also, The Enermax Modu82+ is quite a bit quieter as well.
I went from Seasonic S12600 to PC Power&Cooling Silencer 610 to Enermax Modu82+ 525w. The S12 and modu are far quieter than the silencer.
The Enermax does make a low hum, which I'm not sure I really like but I can't hear the fan and unless my system is booting up or seaking, it is the only component I hear.
