This year I upgraded my desk with an adjustable base, The Topsky desk frame, which has paired well with an Ikea Countertop.
The frame doesn't come with a way to mount the power supply, so I designed a bracket that fits between the center supports, attached with 4 small screws. It compresses the rubber feet on the power block just enough to hold its position but is easily pulled through the brackets by hand.
Hoping this helps you organize a little easier.
