A:Answer Hello Alan,
Based on the devices listed I would estimate your connected load to be ~700 watts (if all devices are on and pulling their maximum required wattage, which is unlikely).
55" OLED TV ~100 Watts
PS4 ~ 140 Watts
Directv Receiver ~ 25 Watts
Audio Receiver is 80W per channel with 5 channels ~ 400 Watts
Total ~ 700 Watts
This would provide you with an estimated runtime of ~16 minutes when the power goes out, though again this would be if all devices were on and pulling max power. You can probably expect longer runtimes if some of the devices are off or in a low power state at the time of outage.
The unit also outputs a sine wave on battery backup so there would be no compatibility issues with any of your connected devices. It outputs power indistinguishable from your utility power.
I think this model UPS would be a great fit for your home theater system.
Please let us know if you have any other questions or concerns.
