A UPS gives you approximately 5-15 minutes of power if your house suffers a power cut.
Living in a rural area we get more than our fair share of power outages and happily these UPS boxes keep our systems running during small interuptions and perform orderly shutdowns when interuptions are longer than 5-10 minutes.
Most power supplies can handle really small outages like the ones when you see the lights dim and flicker.
However, if the interuption lasts longer than 1 second then your system may have to be restarted with the possibility that some disk writes did not take place or you may even end up with a corrupted disk drive.
With a UPS, interruptions longer than 5 minutes will cause the UPS to commence an orderly shutdown or put the system into sleep mode.
Of course, laptop users have always had battery backup by design.
I have usually purchased a UPS with each new PC.
Currently, they cost from around £65 and up.
