I'm looking for advice/guidance/comments to determine the specification of a UPS to protect my (oldish) main desktop pc. It has an i5-7400 cpu, 1 M.2 SSD on the M/B, 1 sata3 SSD and 1 mechanical sata3 HDD. Intel UHD graphics on the cpu. O/S is Win 11 pro 64 bit. It has a 650 watt Thermaltake PSU. It connects to a 40inch Skyworth TV. I just bought a power meter plug from Lazada to see what power was being used. I plugged the PC , TV, external USB HDD and an 8 port USB hub into a 4-gang power strip, which was plugged into the mains via the power meter plug. I then played a video on the pc, started word, excel and outlook. The power meter showed that less than 100 watts was being used. Does this seem right?
