Got this one for my first pedalboard, it's currently powering ten pedals easily, including a Digitech Whammy, and it could take more.
It seems to keep noise down quite well, and there's a good variety of outputs and voltages available. Perhaps other units offer a better choice, but for what I needed, this one was perfect. I have yet to try the 12V outputs, but I imagine they work just as well.
I did find the included cables a bit lacking. There's a good variety, but I barely had enough of the regular cables to put the thing together, going to have to grab a few more for future expansions.
Bottom line, this is a great PSU for a medium-sized pedalboard, feels durable, quiet and handles what you give it.
