The best UPS battery backup for PC gaming in 2021
The best UPS backup will ensure your precious gaming PC survives a blackout or surge, which might be an especially high risk to your invaluable components in parts of the world prone to extreme weather. Which has become a far greater proportion of the globe in recent times.
These UPS battery backups aren't a common co-purchase when shopping for a high-end gaming PC build... but perhaps it should be. The best uninterrupted power supplies will also offer protection from the most minute fluctuations in outlet power, which means as long as your PC is fit with one of the best power supply units for PC, it will receive cleaner power over the duration of its life. That's a pretty big deal for longevity, as it will essentially run on the electrical equivalent of Premium Unleaded.
A UPS for your PC isn't a permanent fix for loss of power but an important stay from immediate power loss. Should you suffer one, the best UPS utilises its internal batteries to deliver a steady flow of power, for a limited period—just enough time to save your work or get to a save point before shutting down your PC safely. It also acts as a surge protector, for extra peace of mind.
The best UPS for gaming PCs
The CyberPower CP1500PFCLCD 1500VA is one of the best UPS on the market. Several factors contribute to it being our top pick for most gamers. First, it has enough juice to handle most gaming machines on the market, even if you're running dual GPUs. Unless you've got systems with ten hard drives, quad-way GPUs, and other accessories, the CP1500PFCLCD should have enough juice to last 10-20 minutes (longer if you have a more moderate rig) if a power failure occurs.
One of the most critical features of the CP1500PFCLCD is its true sine-wave output. Most UPS backups in their price range only provide sine-wave simulated production, a stepped sine-wave that approximates what you get out of your wall outlet. Some electronics are sensitive to simulated sine waves and will behave abnormally. At $214, having true sine-wave output is unheard of, so kudos to CyberPower deliver quality output.
For smaller accessories and network equipment, the CyberPower EC650LCD is the best pick for most. Coming in at just over $70 for 390W/650VA, the EC650LCD has enough power reserves to keep the average home network alive for well over 15 minutes, which is enough time to exit your game/applications, save all your work through the network, and shut everything off gracefully during a power outage.
The EC650LCD is small enough to hide away, taking up very little desktop room for a 390W unit. One of my favorite features of the EC650LCD is its array of ECO ports. These ports can be managed and timed to turn on or off, depending on your schedule or use case. The ECO ports will also power down accessories like your speakers and display if your PC is asleep or powered down.

The name APC is synonymous with high-quality UPS products. I use three of the company's Smart-UPS professional level units at home: two 1000VA units for my network and NAS gear and one 1500VA unit for my PC and displays.
APC's BE600M1 is excellent at providing both battery and surge protection for the devices you use most every day. That is your phone and possibly a tablet. However, it has enough power reserves for you to plug in at least a router and a single display. If you only plan to use the BE600M1 to power a Wi-fi router, the unit will have enough juice in it to let you browse the internet in peace for several hours, even if the electricity in the rest of your house is gone. Priorities.
The best part of the BE600M1 is its size. Most UPS are large and belong on the floor, but APC encourages you to put the BE600M1 on a desk. The unit provides a single 1.5A USB port for charging a phone or tablet, so you don't have to use your device's power adapter, which is inevitably a wall wart that potentially overlaps another socket or two, so you free up sockets for other devices.
The best UPS for PC gaming FAQ
How long will a UPS last?
An uninterruptible power supply that rates at 1500VA should run your computer for a little under an hour. But if you're trying to run your PC and your monitor from it, then you're probably looking at more like ten minutes of up-time. A 650VA, at peak load, will maybe net you something in the range of seven minutes, though that is obviously with a far lower peak wattage.
What type of UPS should I buy?
There are two types of uninterruptible power supply to look out for when shopping around for your gaming PC: sine-wave and simulated sine-wave.
Sine-wave UPS backups deliver a smooth, consistent oscillation of AC power directly to your PSU. These are often the only type of UPS you'll find recommended for gaming PCs due to their efficiency and clean power delivery.
What's the difference between sine-wave and simulated sine-wave UPS?
A pure sine-wave signal will be a match for the AC mains power your PSU is expected from your mains. Essentially, your PC shouldn't know the difference between your UPS battery power and the power coming from the wall.
Simulated sine-wave UPS deliver a stepped, approximated waveform using pulse-width modulation (PWM). That's the same concept used to control PC case fan RPM. These are often far less expensive than pure sine-wave UPS and can be useful for peripherals, small devices, and monitors. However, since the waveform is not always exact, these may not function as intended with PSUs that demand a stable and consistent input.
When your UPS detects a power surge or cut it will switch to battery power. How it delivers that battery power to your PC or accessories is when sine-wave versus simulated sine-wave matters most. That's because some PSUs will actually recognise a simulated sine-wave frequency and shut down suddenly to protect themselves from the unexpected oddity in power. Thus, your UPS won't actually be saving your PC from a loss of power.
