Things to Consider in a UPS Meant for a Personal Computer

Before you make any purchase, here are some important factors to keep in mind. This will help you pick the right UPS for your PC according to your budget and usage.


Never go after a UPS that has no warranty. All the UPS units listed in this guide come with at least 2 years of warranty. The warranty covers the battery replacement and the UPS itself. If something goes wrong with the UPS or battery within the warranty period, you are entitled to a replacement.


This is one of the most crucial factors to consider before buying a UPS for home use. The more wattage a UPS has, the more devices you can connect with your UPS.

The table below can give you a better understanding of the wattage rating on a PSU.

UPS WattageBest Suited For
200WGaming console or a PC monitor
400WEnough to power a desktop PC and a monitor
600WIdeal for a low budget gaming PC with a GPU inside
800WGood for a mid-range gaming rig
1000W and aboveBest for a high-end gaming computer

Please keep in mind the power supply unit of your computer before buying a UPS. High-end gaming PCs may come with 700W+ PSU, therefore, you will need a minimum of 1000W UPS in that case.

Battery Backup

The power backup of your UPS depends upon the capacity of the battery that is installed in it. In case of a power outage, a good-quality UPS meant for a low-budget PC may last anywhere between 30 to 45 minutes. Within this time, you can easily save your progress and shut down your computer.


Finally, these were some of the best UPS battery backups to be used with a personal computer. Our recommendation is to go with APC Back-UPS BX1500M if you are low on budget and need a reliable UPS. And if your concern is to get a UPS for a gaming computer, then Vertiv Liebert 1500VA UPS packs more wattage and power to let you enjoy few more minutes of your favorite game.
