Have run several Pi3 Model B's over the past few weeks with no problems. Technically the Pi requires 12.5W of power for all functions to work properly, but in the right applications this will work just fine. Be careful if you want to connect a bunch of peripherals like USB devices, cameras, etc. POE-Texas / WiFi-Texas technical support is excellent.
