Need assistance with wrapping up the UPS decision.
Hello,
I’ve gone through the key issues to determine the right UPS. Could you please check the questions, responses, and selected models? Your input would be very helpful. I reside in the United States where wall sockets are rated at 120 volts.
1. Question: How long should I wait during a power failure? Answer: Approximately 10 minutes to preserve a game or office program.
2. Question: What is the wattage of my PC and the required VA rating? Answer: According to PCPartsPicker, the components listed use about 560 watts. Using a 0.7 power factor for a gaming machine, I think a 1000VA to 1200VA PSU will be adequate for the 10 minutes needed. My initial estimate is the total wattage to cover. 560W multiplied by 1.25 equals 700W. This accounts for an extra 25% in case I need more power or upgrade parts. The second approach calculates VA from watts. With a 0.7 factor, VA comes to 1000VA times 0.7 equals 700W, or 700W times 1.7 gives roughly 1190VA, which rounds to 1200VA.
3. Question: How often do blackouts and brownouts happen? Answer: Blackouts occur roughly every 1.8 months annually, while brownouts are more common. Therefore, a line-interactive unit seems better suited.
4. Question: Are any PC components using active power factor correction or sensitive electronics? Answer: Not sure; I opted for a pure sine wave output.
5. Question: How many UPS outlets should be connected to the battery backup? Answer: At least four—one for the PC, two per monitor, and one for future devices like speakers.
6. Question: What is the intended use of the PC? Answer: Primarily for gaming and using Microsoft Office. I avoid overclocking or heavy workloads.
Based on my responses, here are the UPS options under consideration:

with an old PSU lacking PFC, it works fine; with a modern PSU featuring PFC, the power factor sits between 0.8 and 0.99. That means an 80+ bronze rating around 0.8+, an 80+ platinum near 0.9x+, and some differences depending on the load. It shouldn’t fall below a 0.8 power factor at any time.
system specs: CPU 142 watts, cooler 6 watts, motherboard 7 watts, storage 2x6 watts, graphics card 2x8 pins (300 watts) plus PCIe slot (75 watts) – maximum possible power, BIOS set to 315 watts.
monitor consumes up to 97 watts (maximum), possibly some peripherals or RGB (50 watts), and a couple of RAM sticks (8 watts). Overall peak usage reaches around 650-700 watts.
you don’t have a wall meter? that would show your actual gaming power draw from the wall. But a 1000-1200VA UPS should be more than enough.
