In my area we don't have any power cut issues . It never happened in past 3 years. I know the main purpose of UPS is to provide battery backup for a small amount of time so that we can turn off our pc if main power fails.However my main purpose is to protect my pc from power surges.I want to protect my pc from power surges .My 5 yrd old motherboard just got damaged due to a power surge .Do i really need to buy an UPS ? is there any other ways to protect my pc in case of a power surges in future.
