Power surges and failures are common issues that can appear and affect your sensitive computer components or electronics. If you need a protective barrier that will also keep your data safe in the event of a power outage, getting an Uninterruptible Power Supply (UPS) is the right solution. While conventional power strips should keep you relatively safe from surges, you’re still vulnerable to a plethora of other problems such as blackouts, brownouts, and line voltage. You might also be interested in our articles about the best nas and the best power supplies.

UPS devices are basically like power strips equipped with large batteries which come with a buffer against power supply interruptions. Even if the lights suddenly go out, the computer can seamlessly switch over to battery power and retain your important data. There’s usually a generous amount of time for you to save everything and turn off the PC without worries. Besides providing the much-needed power, a UPS can also regulate the voltage and protect against surges.

As not all UPS units on the market are created in the same way, you will have to look for some particular features according to your more specific needs. The main aspects to analyze are:

1. Power requirements

Before you think about anything else, it’s essential to figure out the total electrical load of the devices that you plan on using the UPS with. A good estimation can be done by adding the wattage of each connected device. You will need to dig into the manufacturer’s documentation for this info or you can simply check the equipment nameplate. The basic idea is to get a UPS which can handle a larger capacity than the total wattage of your equipment. To be safe, it’s recommended to make sure that the UPS offers a 20% to 25% higher output watt capacity.

2. Backup runtime

This is measured in minutes and it refers to how long the UPS can give backup power to your devices when the power’s out. Consider your needs to make the best selection and keep in mind that the runtime decreases as the power capacity goes up.

3. Outlets

Getting more receptacles than you currently need is always recommended. You never know when the time comes to add extra devices so it’s a good idea to plan ahead. Another aspect to be aware of regarding the outlets of a UPS is that on most units you can discover that not all receptacles are protected by the battery backup. Some outlets can only offer surge protection so be sure that you choose in a way to fully cover your critical equipment.

Let’s take a look now at the following list of UPS units that seem to get everything right. These are the most cost-effective options for a UPS and considering the large diversity of their features, you’re almost guaranteed to find something to your liking.
