I live in a semi-rural area where power can fluctuate. Twice in the past month the power has gone out, bringing my MP, monitors, external RAID drives to an abrupt halt. Should I be using a UPS to even out the power supply to my system? And I don't expect to want to run more than 2-3 minutes if the power goes down...but I'd like a graceful exit? How do I determine specs for an Uninterruptible Power Supply?
