Best UPS (Uninterruptible Power Supply) of 2023 (1)

The best UPS (uninterruptible power supply) devices on this page are important purchases for any business - or home user - who needs electronic devices such as PCs and servers that have constant power connections 24 hours a day, seven days a week.

If there's a power cut, even a very brief one, then the results can be catastrophic, as servers could become unreachable, and data could even be corrupted if a computer shuts down suddenly.

That's where the best UPS come in, as if there's a power cut, they will seamlessly switch to battery power, and your devices will remain on and running until the main power is restored, or you can safely shut down the device.

These days many of us are working from home, so buying the best UPS your budget can stretch to is even more important. You may find that you're plugging in a lot more power-hungry devices into your home power supply, and this could lead to power cuts or power surges. Your home likely won't have the power backup solutions that your office does, so buying a UPS for your home could be a very wise investment.

If you are after a cheaper, and more simple, UPS device, then the APC Back-UPS ES - BE700G is a great choice. We would not recommend it for large businesses with lots of mission-critical computers and servers, but it offers plenty of power for homes and small businesses to keep their devices going when the power fails.

This UPS from APC has eight surge-protected power sockets, four of which are covered by the battery backup. All of the eight sockets can take standard three-pin plugs, making it more convenient than the kettle leads found on some UPS systems. You will have enough UPS sockets for your Mac, monitor, and essential peripherals like an external hard drive or router.

However, if you are looking for something more feature-rich, you may want to consider a different UPS.

This is another great UPS from APC, and with the BE600M1, the company has created a UPS device that is ideal for home use. That's thanks to its small and unobtrusive design, and it offers enough power for smaller devices, such as home NAS drives, routers, and gaming consoles.

With careful management, you can keep the power flowing to a router or monitor for enough time to overcome most power cuts. For office use, with lots of power-sapping devices that need to be powered at once, then you'll want to look elsewhere on this best UPS list, but for home users on a budget, this is a great choice.

What is a UPS?

UPS stands for uninterruptible power supply, it's a device that acts as a battery backup in case of an electrical power failure. Small UPS machines for homes and offices supply enough power for a few minutes, so there's time to turn off devices properly without losing any work. Larger UPS systems can even last a few hours, but you generally won't find these in homes or small offices.

How to choose the Best UPS for you?

When choosing a UPS for yourself, start with considering where you're going to use it — for your home or office? If it's a small home or office that you need to power, then a tiny UPS will work fine.

You'll want to evaluate the size and form of the UPS system. While some are compact and can be fit on desks, others are larger and either in the form of towers or rack-mounts. There are some UPS machines that can be used both as towers or rack-mounts.

Then, you'll want to assess how much power your devices require and how much time you need the electrical supply for once there's a power cut. If your device takes a few minutes to turn off, make sure to select a UPS system that can provide sufficient runtime for that.

The best UPS: How we test

We've tested these UPS machines across numerous points, starting with what environment they're best suited for — home, small office, or server farm?

We looked at how much power these devices supply, how much runtime they offer during power cuts, and their form factor (desk, tower, or rack-mount). We analyzed their specifications, like the input voltage, output capacity, battery runtime, and recharge time. We also considered the number of outlets they had and whether there was sufficient spacing between them for wide plugs.
