It's hard to keep things organized and in place on a test bench so I came up with a way to hold the power supply and video convert board in place. Then I threw in a power switch since unplugging it was too annoying. The GBS-8200 Video Converter board is pretty generic but the power supply I'm using and on/off switches are shown below.
