Why and How to Buy a UPS

All electronic devices prefer constant, pure electrical power, but no AC wall socket provides it. Power levels fluctuate all day, and power outages are common. The result is constant hammering on the power supplies in your devices — including your computer — and a damaged power supply is among the most common reasons for device failure. In fact, the latest Mac Pros seem especially sensitive to power issues.

Fortunately, there’s an easy, inexpensive solution: a UPS (Uninterruptible Power Supply) with Automatic Voltage Regulation (AVR). The battery provides power during brief power outages, and AVR provides a constant power level. Only the better UPSes feature AVR, so be sure to look for that.

One UPS supports many devices and should last longer than you’ll keep your computer, making it a cost-effective investment.
