UPS safety ?
Sure, I understand. It's important to use a proper UPS rather than a cheap standby model. I'm actually running two of them myself—CyberPower CP1300EPFCLCD, which is line-interactive with true sine wave, and I've experienced surges, brownouts, and blackouts too. My UPS has handled all of them and kept my PCs functioning smoothly.
Did you receive those once you compiled the list of wattage numbers?
Not only the wattage matters, but also several other factors:
* accurate sine wave generation (simulated sine isn't suitable for active PFC PSUs; square waves are even less ideal, only practical for tough hardware like generators)
* line-interactive design is inferior; standby topology performs worse, while online double-conversion offers better performance but comes at a higher cost. Delta-conversion is optimal but hard to find under 1kW capacity
* trustworthy manufacturers are preferred (recommended brands: TrippLite/Eaton, Delta Electronics and APC)
* suitable for residential applications (minimal noise output at 0dB(A))
* user-replaceable batteries available
* sufficient Schuko outlets (6 units)
* fair pricing around €230.10
* included equipment warranty: €50,000 coverage within 2 years – meaning CyberPower will reimburse hardware replacement costs up to €50,000 if the UPS fails within two years
Regarding power requirements, previously I needed only about 250W under full load. I chose a 1300VA/780W unit to significantly extend battery life from just a few minutes to roughly 20 minutes. During power outages, I no longer need to rush to save files or shut down the system; I can continue working normally.
I currently own two units, one for each desktop PC, and have used them for approximately six years.

Also, I intend to upgrade my UPS systems because after the GPU and PSU upgrade, the anticipated maximum draw would rise to around 550W. Therefore, I plan to purchase CyberPower CP1600EPFCLCD (1600VA/1000W) units.
