I have my Mac Mini attached through the Ps Audio UPC-200 at home and the BPT Custom at work. Both just surge units and the Mini at work has gone through several power outages with no problem. The thing I can't do is have them do a restart after AC power is back without UPS so I will probably buy an APC unit for the home system as they have always worked very well for me. The one CyberPower unit I had, one of their cheaper models, was a piece of shit and kept cutting over to battery for no apparent reason and I scrapped it after about three months of annoyance.
