Know What You Want – and What You Want to Avoid

what to avoid


As with any electronic device, all UPSs are not created equal. Here’s what you want in your UPS, and what you should steer clear of.

  • Power: Use this online load calculator to determine the total electrical consumption of all the equipment you plan on connecting to your UPS. Then look for a UPS with an output watt capacity 25 percent higher than the number you calculated.
  • Runtime: How long do you want or need your computer to run after a power outage? Whether you just need a few minutes to power down safely, or you want to be able to keep working longer, this is an important feature to consider before purchasing a UPS. Keep in mind that the number of devices you plug into your UPS will also affect runtime, with more devices resulting in a shorter runtime.
  • Space-Saving Form: The two most common UPS forms are tower and rack-mount. As the name implies, tower models stand up on a desk, shelf or floor space. These are the most common UPSs for desktop computing and home workstations. Rack-mount models are made to be installed on the wall in a rack. They are more commonly used with servers and networking.
  • Software: It may be useful to buy a UPS that includes power management software. This gives you the added protection of software that will manage and monitor your UPS without requiring any action on your part. Therefore, should the power go out while you’re not home, the UPS’s software will save any open work and shut your computer down safely.
  • Stay Away From: To save on future costs as well, avoid UPS models with batteries that must be changed by a professional technician. User-replaceable batteries mean you can make the switch by yourself, which will save time and money.

Identify Your Optimal Battery Size

At the very least, you want to have enough battery life for the time it will take your computer to shut down safely. However, you need to factor in not just battery life for the operating system, but also for the monitor and any other equipment that will be plugged into the UPS.

If you’re into math, you can calculate the energy usage of all your equipment How Much Power Is Your PC Using? Computer power consumption can be estimated. Most of the components inside a PC have specific minimum and maximum power draw figures and, because quality control is so tight, it’s rare of a part to break... Read More yourself. The easier approach is to use manufacturer estimates of battery life based on the size of the battery. These estimates tend to be conservative, so if anything you’ll end up with a little more than what you need, which is a much better situation to be in than not having enough.

There are also online calculation tools that help you find the ideal UPS and battery size based on an estimate of extra power you may need for future devices, your optimal equipment runtime after a power fail and the voltage system you use based on your country. For example, you may only want the minimum time needed to shut down your computer Automatically Turn Off Your Computer With Shutdown Timer [Windows] Read More or you may want an hour or more to continue working after an outage.


It may take some time and research to find the best UPS for your needs at the best price, but putting in this effort will pay off with peace of mind.

Since severe weather events are likely to become more frequent, power outages and brownouts will also become more common. Protect yourself now to avoid a data disaster in the future.

    Afaik it's a bad idea to connect printers, especially Laser printers to the same ups you use for the pc. During printing laser printers suck up a lot of power,which can quickly overwhelm the ups,shorten its lifespan or damage it. Best advice is to power your laser printers on a separate outlet ,or if you have a larger photo-printer /plotter that you use proffesionally,buy a separate ups for it.

    Mr. Howard Blair... is there something wrong with your thinking? Do you not understand the meaning of certain words? Let me help you...

    The article stated, "The two MOST COMMON ups forms...", it did not state ALL.

    There is nothing "Odd" about the CyberPower unit that does not "disagree" with the article. In fact, it would AGREE with the article when it comes to saving money - the unit advertised for $39.95.

    So, if you want to be heard you first have to make sense.

    Once you find one with adequate power output and if it has a removable 12V battery you can almost always remove the battery and connect it to a car battery for extended power and you can recharge it with your car if need be. I keep two, one connected to the car and one connected to the UPS for ping-ponging. I don't think it probably a good idea to connect anything but a fully charged car battery. A battery tester with a load is always a good idea.

    You can keep going this way as long as you have gas in your car so I make sure my tank is never much more than 1/4 down.

    When you do have a power failure, you don't know if it will last 5 minutes, 5 hours or 5 days. Think about what you will do in the event of a full power failure. Typically, you stop what you are doing, save your work and shut down normally. This is what the UPS software does for you if you don't override it. You do not want to continue playing that power hungry game. You do not want to continue updating that spreadsheet, You do not want to keep uploading cat pictures to Facebook. If you feel you absolutely must, use your cell phone to post a quick Twitter to tell people you are down for a power outage. You do not need multiple monitors. You do not need your printer. Each extra gadget plugged into your UPS cuts down on the time it can function before it dies also.

    The only things that should be plugged into your UPS are your computer (AKA CPU, AKA that box that everything plugs into) A single monitor ( plug other monitors into a separate supply and not the UPS) And, depending on your personal need MAYBE the modem and router. The fewer things you have plugged in the longer you can take to shut down. If you have a server or NAS, you may need extra USP capacity (or a second UPS just for them)

    Once your computer is shut down, You can use the remaining battery power to run an emergency light or charge your cell phone. Be sure to use a low power LED and not an old fashioned incandescent bulb. Depending on the left over power you could easily get several hours of low level light during a big power failure. The quicker you shut down the computer, the more battery life will be remaining for your light and phone.

    Be sure to test your UPS - those batteries don't last forever and when you need a UPS it's too late to test it.

    "The two most common UPS forms are tower and rack-mount."
    Funny, the CyberPower unit you link to (link to Amazon!) is neither of these; it's a "fat powerstrip" form, mean to lie on a desk with outlets across the top. Odd that an item in your article disagrees with the article itself. :p
