You're stretching the cost of a UPS a bit there Ripley. I bought two UPS devices for system for less than I paid for a single graphics card. You will never be able to buy an entire system for that same price. Furthermore, an adequate surge protector will cost you half of the price of a single UPS, and the UPS provides surge protection also!
Then you speak about a PSU preventing power cycling? Sorry, but that's just untrue. Also, why are you concentrating on surges? The most common issue is sags. Sags damage equipment slowly over time. You claim that you have never known of a PC failure because of electricity, yet there are thousands cited via Google including many that were not saved by surge protection.
The one instance I cited where I lost a motherboard came through across the network line, not through the UPS. On the system that lost the UPS it was battery failure, and the motherboard survived.
So the only thing your posts have accomplished is demonstrated your lack of knowledge concerning electricity, and your inability to understand the written word.
Just last February I recall reading a story where a German forensic team had determined the precise moment a recording had been made because of the electric hum from appliances in nearby sockets. So, I know your electric grid suffers the same issues as anyone else. The only thing saving you so far has been the fact that lightning storms are less frequent. Ignorance is bliss as they say.
