A UPS, or uninterruptible power supply, is a battery backup that instantly powers your equipment when the mains fails, giving you time to save work and shut down safely and protecting gear from surges and brownouts. The difference between a great UPS and a frustrating one comes down to its capacity and runtime for your equipment, the quality of its power output, and its protection and features. The picks below earned their tiers on real capacity, power quality, protection and value.
The first thing to work out when buying a UPS is how much capacity you need, which depends on what you want to power and for how long. Add up the wattage of the equipment you will connect, such as a computer, monitor, router and console, then choose a UPS with enough capacity to run them, with a higher capacity giving you longer runtime to save work and shut down or to ride out a brief outage entirely. The next important factor, especially for modern and gaming PCs, is the type of power the UPS produces during a switch to battery, since many modern power supplies with active power factor correction need a pure sine wave output like the CyberPower PFC Sinewave models provide, whereas a cheaper stepped or simulated sine wave can cause them to shut down or behave oddly, so match this to your gear. After that, look at the number and type of outlets, since good UPS units separate battery-backed outlets from surge-only ones, and at features like an informative display, automatic voltage regulation that smooths over brownouts without using the battery, and software for safe automatic shutdown. Finally, remember the battery is a consumable that needs replacing every few years, so choose a brand like APC or CyberPower with available replacement batteries.

Add up the wattage of the gear you want to power, such as a computer, monitor and router, then choose a UPS with enough capacity to run them with headroom. Higher capacity gives longer runtime to save work and shut down or ride out a brief outage.
For a modern or gaming PC with an active-PFC power supply, yes, since a stepped sine wave can cause it to shut down or behave oddly on battery. Pure sine wave models like the CyberPower PFC Sinewave are safe for these. Simpler electronics work fine with standard output.
Work out how much you need to power and for how long. Add up the wattage of your computer, monitor, router and other gear, then choose a UPS with enough capacity to run them, with higher capacity giving longer runtime to save work and shut down or ride out a brief outage. Buy some headroom rather than the bare minimum.
For modern and gaming PCs, the output type matters. Many power supplies with active power factor correction need a pure sine wave output, like the CyberPower PFC Sinewave models, while a cheaper stepped sine wave can cause them to shut down or behave oddly. Match the output to your gear, choosing pure sine wave for high-end PCs.
Check the number and type of outlets, since good units separate battery-backed from surge-only outlets. Look for an informative display, automatic voltage regulation that smooths brownouts without draining the battery, and shutdown software. Remember the battery is a consumable, so choose a brand like APC or CyberPower with available replacement batteries.
