5 Best Computer Uninterruptible Power Supply Units in 2018

Routinely used by businesses and increasingly more often found in home offices and right next to powerful gaming rigs, uninterruptible power supply (UPS) units are the best defense against sudden power outages, surges, and circuit breakers that trip whenever someone plugs a vacuum cleaner into a wall socket.

Best Computer Uninterruptible Power Supply UPS Units

Modern UPS units come with a wide range of ingenious features designed to protect your electronic devices and help you stay operational even during an extended blackout. Apart from features, the main difference between various UPS units on the market is their battery capacity.

Some uninterruptible power supplies are about as large as heavy-duty surge protectors, while others dwarf microATX PC builds. Because the batteries inside UPS units don’t last forever, it’s not cost-effective to purchase a larger UPS than necessary. Consider how many electronic devices you need to keep operational should a power outage occur, how many watts these devices draw in total, and how much time you need to save your work.

CyberPower CP1500AVRLCD

The CyberPower CP1500AVRLCD is the most popular UPS on Amazon. Over 2,500 customers have given it 5 stars, which speaks volumes about its reliability and utility. Equipped with 12 outlets, including network and coaxial lines, this beefy UPS has a capacity of 1,500VA and 900W, making it suitable even for high-end gaming computers and desktop workstations. CyberPower recommends it for home and small office computers, wired and wireless network routers and modems, home theater systems, game consoles, and personal electronics.

Thanks to the included PowerPanel Personal Edition software, you can control and monitor the CyberPower CP1500AVRLCD UPS from any computer. The software records the time and date of power outages, allows you to run self-testing procedures, and more. The CP1500AVRLCD sports an attractive design with a large LCD status display and a backlit power switch. Not only is it Energy Star qualified, but the manufacturer also offers a 3-year warranty.

APC Back-UPS 550VA

With its modest maximum output capacity of 550VA and 330W, the APC Back-UPS 550VA is perfect for Internet of Things devices, modems, external hard drives, and home security systems. It comes with 8 outlets—4 of which provide battery backup, while the other 4 only provide surge protection. An electronic device that draws 10W can stay operational for around 3 hours during a blackout when connected to this UPS.

APC ships the APC Back-UPS 550VA the PowerChute software, which provides safe system shutdown, preventing potential data corruption. The software can also test the UPS to find out if it needs to be replaced. Small UPS units like this one have their place everywhere where power outages don’t occur often enough to warrant a purchase of a full-sized UPS.

APC Smart-UPS 2200VA

This 2200VA UPS from APC doesn’t mess around. It’s just as large and heavy as a desktop PC, and it even has a fan to keep it cool during extended power outages. It features 8 NEMA 5-15R and 2 NEMA 5-20R output connectors, an RJ45 connector, several USB ports, and a SmartSlot, which makes it possible to further extend the connectivity of this UPS.

Thanks to the sealed lead-acid battery with suspended electrolyte, the APC Smart-UPS 2200VA is maintenance-free and fully leak proof. The battery can be replaced with a spare, although it should last several years even when used frequently. Just like all APC uninterruptible power supplies, the Smart-UPS 2200VA also comes with the PowerChute software, which provides safe system shutdown in the event of an extended power outage while preventing potential data corruption.

Tripp Lite 1500VA

The Tripp Lite 1500VA will make sure that terrible weather won’t ruin your day ever again. When pushed to its limits, it can remain operational for over 2 minutes—enough for you to save your work and safely turn off your computer. With a load of 200W, which is much closer to how much electricity the average desktop computer draws, the UPS has a runtime of over 30 minutes. Besides its high battery capacity, the Tripp Lite 1500VA also has a feature called automatic voltage regulation (AVR), which enables the UPS to detect when input voltage is out of bounds and correct it without using the battery.

The large front-facing backlit LCD display provides rich status information, including input/output voltage, battery voltage, input/output frequency, load/charge level meters, output load percentage, and more. You can either manage the UPS using the display or use the USB port with Tripp Lite’s free PowerAlert software.

CyberPower CP825AVRLCD

This 825VA, 450W UPS with 9 NEMA 5-15R outlets and protected network and coaxial outputs is easy to set up, quiet, and compact enough to fit inside any office. Unless you have an extremely power-efficient computer, you won’t be able to get much work done when running on the UPS alone, but the battery gives you enough time to comfortably save your work and shut down your computer.

It ships with an USB cable and CyberPower’s management software, PowerPanel Personal Edition. Once you connect the UPS to your computer and install the software, you can remotely manage its advanced functionality, perform self-tests, browse through logged events, and more.
