After mounting the thunderbolt dock for my new workstation laptop I saw that the power supply was going to cause some clutter on my desk. Drew out the power supply mount to match the dock wall mount so everything can be tucked neatly behind the monitor which freed up a large amount of desk space. Hopefully this will work nicely for you. Just like the dock mount, this is set up to use #6 screws and wall anchors.
