Ive tested the battery back up and haven't had any issues. I read some people say that the power supply may hum or the mini would just do a hard shut down. Mine did not hum and continued to run well.
I'd appreciate any answers
Not sure if this helps you or not, but I have a 2011 base and a APC UPS myself. Just this past Thursday I had a blackout in the morning. My first test of how the APC and Mac play together. All went well. It switched without missing a beat to backup power. I didn't hear a hum at all but the beeping from the APC sure was annoying.
Again, this was a 2011 so I don't know if the 2012 differs in power supply or not.
