Il best uninterruptible power supply for PC (UPS) is an essential purchase for any business that relies on computers, servers and other electronic devices running 24 hours a day, seven days a week.

For many businesses, if a power failure occurs, even if it is a very brief one, the loss of energy can be catastrophic. Servers and files could become unreachable - or even worse, corrupted - from a sudden shutdown. You will need to equip yourself with the best UPS that can prevent disasters when the power goes out, switching, without interruption, to battery power to keep powering the devices until the main power is restored.



How to choose the best UPS for PC

Uninterruptible power supplies, like other hardware, have more or less important features that are useful and worth considering.

Runtime

A longer runtime means that you will have more time to perform the appropriate actions before your computer runs out of "power". Therefore, depending on the type and behavior of the device, you need to decide on a correct UPS utility. For normal PCs, two minutes or even one is enough time to save all data and shut down the device, while, for example, servers require much longer shutdown periods, not to mention that many of them don't they can't even be turned off.

Maximum power

Higher supported power means you will be able to connect more devices to the UPS. Keep in mind that traditional PCs usually have a power supply of around 500W of power, while the gaming PC power supply, depending on the configuration, can go well over 1000W. More importantly, if, for example, you has a PC with a 600W power supply, it would be a wise decision to opt for an uninterruptible power supply with at least that specific amount of supported power.



Warranty

The warranty is always an important aspect of any product purchased. However, as the nature of UPS devices is vulnerable, it is highly recommended that you take this aspect quite seriously and choose devices with the longest warranty period possible.

Stores

More outlets mean you'll be able to connect more devices - of course, if the supported power allows. Also, keep in mind that not all sockets are created equal and that some only offer surge protection, while others also offer battery backup. For this reason, pay more attention and find the best combination.
