I can't find any info on whether or not the Studio's power supply is active PFC. 🧐

Thoughts?

Bonus question: How many watts is the Studio Display? 🤔

I guess it depends on what you want to do if the power goes out? Continue working/playing or simply have time to save your work and shut down? If the former, I suppose err on the side of caution and buy a pure sine wave UPS. Otherwise, there's probably no real benefit.

FWIW the UPS I use with my 2019 iMac is simulated sine wave and I notice no performance difference between UPS battery power and regular power.

  • Standby (Sleep): Low power state that is entered after the display receives instructions from a connected host computer set to off/sleep. This mode is characterized by a blank screen.
  • On: The display is connected to a power source and a host computer. Display brightness was set as defined by ENERGY STAR Program Requirements for Displays. Auto-Brightness was turned off and the display was not providing charging power to the host computer or any other peripheral devices.
  • Power supply efficiency: Average of the power supply’s measured efficiency when tested at 100 percent, 50 percent, and 20 percent of the power supply’s rated output power.

The Studio (like all recent Apple desktops) will have very effective active PFC in the power supply. It is a good thing.
