TESTING METHODOLOGY

    It's been a while since I had a UPS on my test bench and so I decided to slightly tweak my testing methodology. I will again be using a TV set to match the same wattage, but I will also be using a short throw projector model with a media player and even my newest Intel Core Ultra 9 285k test rig (mostly for stability purposes). Once again, power draw is not 100% fixed but the minimum and maximum numbers during all tests don't exceed 10W for the first and 20W for the latter (so do keep this in mind).

    To simulate real power outages, I will be turning the corresponding power switch in the lab a total of 5 times (5 for each test), 3 of which I will pushing it back on immediately and 2 which I will allow a couple of minutes to pass. If any of the UPS models I test fail to protect the connected equipment (or fail to keep it running) I will be sure to mention it at the end of the review.

    As for noise levels I’ll be using the ExTech HD600 decibel meter placed 5cm away from each UPS model (i will not however be recording beeping sounds coming from their internal speakers).
