But before you start shopping for the best rackmount UPS, check out our list of the things you need to consider while deciding on what device is best for you.

Things to Consider

You might be wondering how you’re supposed to know which UPS is right for you. The right rackmount UPS will vary by individual and use case so, before going through this list of the best rackmount uninterruptible power supply devices, check out some of the factors you should consider.

1. Number of outlets

The number of power outlets varies in rackmount uninterruptible power supply devices. Before you make a decision, consider your current electronic devices and projected future devices.

This requires you to consider all the items you have and might one day need to ensure the perfect workspace, no matter your power situation.

2. Power requirement

You can estimate the amount of wattage you’ll need based on the number and type of equipment you intend to connect to your UPS. Check the specification of all the equipment, sum it up and then choose a rackmount UPS with a power supply that exceeds that number.

Pay attention to the power units on each machine when you’re calculating. Some rackmount UPS are rated in only volt amps or watts, while others provide both. If your conversion rate is wrong, you may end up with a UPS that won’t serve your purpose.

3. Backup runtime

The backup runtime of a rackmount UPS refers to how long it can supply power to your devices when the main power is off. This often depends on the number of connected devices and the capacity of the battery. So when you are choosing the best UPS for you, pick something that can run long enough to ensure you have time to securely save your work and switch to an alternative power supply.
