I really wish folks would take the time to actually learn what an UPS does. Especially before telling others what they need or don't need.
Once again, a good UPS with AVR is NOT just a battery backup during power outages. And the batteries in a good UPS are NOT just for backup power. Contrary to what some seem to believe, and want others to believe too, sags and brownouts are much more common than many think - even in countries with modern power grids like the UK and other places that had to totally rebuild their infrastructures after the war.
Even within the home, sags occur. For example, when big wattage items, like ovens, electric clothes dryers, AC units, even hair dryers, dips and sags may occur. A good UPS will use its batteries to boost the voltage back up to normal levels.
Huh? Who's suggesting you spend 1k? Not me. A really decent UPS with AVR can be had for under $200 (£147).
And same regulation? What same regulation? A surge and spike protector provides zero regulation. Chopping off the tops of sinewaves is not regulation. And a decent UPS is NOT just for the computer's power supply. It also protects and supports the monitor(s) and network gear too.
And for what its worth, I used to live in East Anglia, UK. And for sure, power fluctuations and even outages happen in the UK too. And again, destructive anomalies don't always come off the grid. A faulty 1500W, £15 hair dryer made in China can wreck havoc too.
And for what its worth, I spent about 6 weeks in Turkey too. At Incirlik and Ancora. I would never connect a PC without the protection of a good UPS with AVR.
