TP-Link MC200CM replacement PSU

Those will work. Voltage needs to match, power supply only has to minimally match amperage needs of equipment its powering. Max amps TPLinks require is 0.6a, those ps deliver up to 2amp, means they have amps in reserve, this is good thing. I always purchase lps that supply more amps than equipment it powers requires. LPS will run cooler as its not working as hard when not working to it's full capacity.

Match the voltage and use equal or greater than on the amperage.

Thanks very much, that's really helpful. Much appreciated 😊👍

Let us know if it's worth it.

I run 45 feet of fiber and used TP-Link MC200CM converters, although I had to switch to the MC100 converters so the fiber would work with the ENO filter I recently added.  All of those use 9V PSs.  The converter near my router is powered by the same type of ifi PS you mention, and the converter located at the end, near my system, is powered by an HD PLEX adjustable voltage PS - overkill but I happened to have it at my system and it is also powering my Bonn N8 switch.  Can't guarantee I hear differences or improvements but using the better PSs certainly sounds at least as good and helps me maintain my audiophile credentials.
