  • Watts: the watt rating is the load the UPS can carry, so add up everything on the battery outlets
  • Outlets: battery outlets keep running in an outage, while surge-only outlets suit speakers and chargers
  • Waveform: pure sine wave models output a sine wave on battery, and other models use simulated sine wave
  • Runtime: APC lists runtime at a 100W load, and a heavier load runs for less time

Questions About UPS Battery Backups for the M6 Mac mini

Does the M6 Mac mini need a UPS?

The mini runs without one. A UPS adds a few minutes of battery power so you can save work and shut down after an outage, and it filters surges on the way in.

What is the difference between VA and watts on a UPS?

VA is the apparent power rating, and watts is the real load the UPS can carry. Add up the watts of everything on the battery outlets and keep the total under the watt rating.

What is a pure sine wave UPS?

A pure sine wave UPS outputs a sine wave on battery power. The APC BR1000MS, APC BR1500MS2 and CyberPower CP1500PFCLCD are sine wave models, and the CyberPower CP685AVRG and CP1000AVRLCD use simulated sine wave.

How long does a UPS run the M6 Mac mini?

It depends on the load of everything plugged into the battery outlets. APC lists the BE600M1 at 23 minutes and the BR1500MS2 at 73 minutes with a 100W load.
