Zerosurge is a series mode filter. Designed to reduce noise on AC mains. When marketing to the most easily duped, they order the naive to belief subjective hearsay. And provide no numbers. A series mode filter will absorb maybe 600 joules. Then internal passive components saturate. Act like a wire. Rest of a surge (ie hundreds of thousands of joules) then blow right through a Zerosurge unimpeded. Did they say how many joules it will absorb? Did they provide specifications that say how it will 'block' what three miles of sky cannot? No. They are not marketing to people who read ten plus paragraphs. And always demand specification numbers. The effective protector says why it protects from all surges including direct lightning strikes. it does not foolishly 'block' or 'absorb' a surge. Remains functional even many decades later. Is measured in amps; not joules. Costs about $1 per appliance. All that has zero relationship to a fault that threatens human life. If 5 milliamps from the nuclear power plant does not return, then it may be flowing through a human body. A GFCI (conducting 15,000 milliamps) would detect a missing five ma. Then trip; cut off all current. Only to protect human life. PC Gaming computer does not care about those missing milliamps. Does not care about noise filtered by a series mode filter. Since its power supply even makes 'dirty' electricity irrelevant. Home wall receptacle ground only exists to protect humans. If missing, one can use a GFCI to provide same (and other) human protection.
Wall receptacle safety (equipment) ground only exists to protect humans. No appliance cares. Code is blunt as to all options. Summarized here. Point three is relevant here. UPS does nothing to protectd hardware. They target people who will parrot any disinformation. UPS is temporary and 'dirty' power so that unsaved data can be saved. To avert a reboot. It makes no claims to protect hardware or saved data. Otherwise he posted numbers that make that claim. No numbers because no such honesty exists. GFCI is one option to do what the third (safety ground) prong does. Protect humans. As a renter, you cannot install it. The landlord must. Or buy a plug-in GFCI.
