What's a PSU? Did you mean a UPS?
What I use is an Astron power supply with the optional BB (Battery Backup)
option. A size 27 marine / deep cycle battery is attached. This will power
the rig and the TNC during a power failure but not the computer. Upon
restoration of commercial power the computer is set to re-boot into APRS
