Hi guys, i want to purchase a UPS for my home office but i literally have no clue.. The only point of the PSU is to avoid my pc, 5 monitors, 1 imac, 1 router, 1 cctv NVR system to turn off in the event of a powercut. If a powercut happens then i can save everything and turn off my devices manually. So an autonomy of 30 mins or 1 hr is ideal. everything has UK British plugs
Calculate the overall power consumption first. Because no PSU operates at 100% efficiency, determine its rated capacity and increase it by 20% for safety. Include the power usage of each device not connected to the chosen PSU. Add roughly 10% extra for a buffer. Keep in mind that power rating (VA) doesn't always match actual output; ensure the specified wattage is sufficient or higher. You can extend battery life with extra batteries, and most premium UPS models support this feature.
FYI, my 1500VA APC model predicts 15-19 minutes with the 5900X build. It includes a single M.2 drive, Scythe Mugen 5, WD Black 6TB HDD, one 55-inch display, six 120mm fans with limited RGB, and an RTX3060ti paired with an 850W power supply. Since setup, it hasn't exceeded 450W peak draw. For the roughly 30 minutes you're planning with extra monitors, expect around 2200-2500VA, possibly higher at 2800VA or more. Make sure to use a pure/sine wave solution—modified sine waves aren't suitable for motors in hard drives and fans. Edited April 8, 2022 by An0maly_76 Updated, more details
Consider purchasing a power meter that connects to a standard outlet. These devices cost around twenty dollars. Record the wattage displayed, then explore UPS options. Typically, VA ratings are shown in VA units, which reflect apparent power like reactive power. A UPS’s VA rating is often double its real output, but most home models only last a few minutes under full load. Therefore, focus on battery life and load graphs when choosing. In short, measure your watt usage, multiply by two for VA compatibility, and examine battery performance charts to find the right fit. For a specific model, I prefer APC Pro backups—they come in various sizes, are reasonably priced, and their batteries are widely available from different brands.
Your setup is feasible. With a Corsair RMA850 drawing up to 350 watts during gaming and your other devices around 175W and monitors at 40W each, total usage could reach roughly 850 watts. The Amazon link you shared suggests a power supply capable of handling that load. Regarding the second question, yes, you can connect it directly to an UPS if needed, but ensure compatibility with your existing setup.
I just need the time to turn everything off manually without any problems. I’m not aiming for full self-sufficiency in an hour, as that would likely be very costly.
