A UPS (uninterrupted power supply) provides battery backup for your PC and peripherals, giving you time to safely shut down in the case of a power failure and prevent file loss or damage. Additionally, most UPS units include software that can be configured to automatically shut down your equipment. The other benefit is that a UPS doubles as a surge protector, providing protection against voltage sags, spikes, brownouts, and other
power abnormalities. We've selected the best overall based on a combination of performance, value, and features. Your battery backup needs depend on your PC setup (e.g., entry-level, mid-range, or performance)
