I have a low power Atom D525 based computer running windows 7 64bit which I use to stream 44.1khz to 192khz music files to my Touch and to playback files using Foobar and a Stello U3 sdif usb adapter. With a standard atx 350w power supply the fan from this supply proved to be a little distracting in the quieter music moments. After a bit of research I decided to try a Pico 120watt power supply. This plugs directly into the atx 24pin motherboard connector with the power supplied by an external 19volt FSP power brick. This setup is fanless and is therefore totally quiet. The blackness of the background when playing music with the new power supply is certainly very noticable with more inner detail present. Due to the voltage range that the Pico can use it is actually feasible to use a 12 volt battery with sufficient reserve to power the computer. I can recommend anyone that has a low power computer with a noisey power supply to try a Pico module it certainly makes my music playback sound better.
