More 2 or 3 at the same time Razer chroma addressable rgb controller

The Synapse 3 will only detect one Razer Chroma Addressable RGB Controller. You can connect multiple addressable RGB devices, as long as the LED count doesn't exceed 80 on 1 port, or 240 total. There are 6 addressable headers on the Razer Chroma Addressable RGB Controller, and you can daisy-chain your ARGB devices to have more connected.
