For a home computer, buy two UPS units, not one - a 600VA standby for the router and modem, and a 1000VA pure sine wave unit for the desktop and monitor.
Uninterruptible power supplies that keep your computer, monitors, and home internet running through blackouts, brownouts, and surges so you do not lose work or get knocked off a video call.

Cheap no-name 1500VA UPS units under $90 — Battery cells in budget UPS units fail in 12 to 18 months instead of the 4 to 5 years you get from APC or CyberPower, and the replacement battery is rarely a standard cartridge - you end up buying a whole new unit. The $40 you saved upfront becomes $80 in landfilled UPS hardware inside two years, and the equipment guarantee is non-existent or never honored when you try to file a claim.
11500VA / 1000W of pure sine wave with a $500,000 equipment guarantee - the gaming PC and workstation pick that homelab Reddit recommends by default
21500VA / 900W of simulated sine wave at about $200 - the value pick for laptops, monitors, and home network gear without an active-PFC desktop
3The lithium alternative to the lead-acid CyberPower and APC units on this page: 1000VA/800W of pure sine wave backed by a 230 Wh LiFePO4 pack GOLDENMATE rates for 3,000+ cycles, so there is no battery swap every three years. For a desk PC and network gear that need clean power and a set-and-forget battery.
41500VA / 900W of pure sine wave with USB-C charging and 10 outlets - the safe one-box pick for a desktop, monitor, and home network
5600VA / 330W router-and-modem backup that runs 90+ minutes during a blackout - the single best $84 you will spend on home internet uptime

U.S. EIA data shows the average American electricity customer experienced 5.6 hours of power interruptions in 2022, with major-event days driving most of that time - meaning a router-dedicated 600VA UPS that runs 90+ minutes covers the vast majority of real-world outages, while a single-box approach that quits in 8 minutes does not.
r/homelab, r/HomeNetworking, and r/HomeOffice converge on a clear two-tier pattern: APC Back-UPS Pro BR1500MS2 or CyberPower CP1500PFCLCD for desktops with active-PFC power supplies (both are pure sine wave), and a small APC BE600M1 or CyberPower CP685AVRG dedicated to the router and modem for cheap multi-hour internet continuity. The repeated warning across all three subs is do not trust simulated sine wave UPS units with modern desktop PCs - the PSU may refuse to run on battery or shut down hard the moment power transfers.
Popular options we evaluated and passed on, with the specific reason each one fell short of our top picks.
A duplicate pure-sine tier; the CyberPower CP1500PFCLCD gives 50% more capacity for $48 more.
The same job and price as the newer CyberPower CP1500AVRLCD3.
A duplicate budget unit that costs $25 more than the APC BE600M1.
Most home offices buy a UPS the same wrong way: pick the highest VA number that fits the budget, plug everything into it, and assume the box will handle the rest. The result is a 1500VA unit that quits in 8 minutes during a blackout because the user plugged in a laser printer, two monitors, a desktop, a gaming console, and a space heater. The smarter approach starts with a question almost no buyer asks: what is the actual goal of this UPS? For most WFH workers it is one of two things. Goal one is graceful shutdown protection for a desktop and monitor so an outage does not corrupt files or drop a Zoom call mid-sentence. Goal two is internet continuity so that brownouts and 30-second blips do not knock out your router, modem, and laptop charger. Those two goals call for completely different products. A desktop and 27 inch monitor pull roughly 150 to 250 watts, which a 1000VA pure sine wave UPS will run for 10 to 15 minutes - enough to save your work and shut down. A modem plus router plus mesh node pulls about 30 to 50 watts, which a 600VA UPS will run for 60 to 120 minutes and keep you online through almost any short outage. Trying to do both jobs from one large UPS is the most common and most expensive mistake. The second decision is waveform. Pure sine wave (sometimes called PFC sinewave) costs more but is mandatory for any modern desktop with an active PFC power supply, which is essentially every gaming PC, every Mac mini, every workstation built since about 2015. A simulated sine wave UPS will sometimes refuse to run an active-PFC computer at all, and when it does, the computer can shut down hard the moment power transfers to battery. Laptops, monitors, routers, and chargers all tolerate simulated sine wave fine. The third decision is line-interactive vs standby vs online double-conversion. Line-interactive with AVR (automatic voltage regulation) is the right answer for almost every home office: it corrects brownouts and over-voltages without dipping to battery, which extends battery life dramatically. Standby topology is fine for a router-only backup. Online double-conversion is overkill outside a server rack. Sizing rule of thumb: total your continuous load wattage, multiply by 1.6 to get VA, then double the result for headroom and runtime. A 200W desktop+monitor setup wants roughly 600VA of capacity but a 900-1000W UPS for usable runtime. Skip the no-name AmazonBasics-tier UPS units. APC and CyberPower dominate this category because their batteries are user-replaceable in 5 minutes, they have 25 years of firmware iteration behind them, and the $250,000 to $500,000 connected equipment guarantees actually pay out when something goes wrong.
