Surge Protectors vs UPS

Surge protectors vs UPS’s

They’re the same, aren’t they? No, they are vastly different. While both will protect your computer from a power surge a UPS (Universal Power Supply) will give you time to shut down your computer in the event of a power interruption or shut it down properly for you if you aren’t around.

After the recent winter’s storms many people discovered that they are still susceptible to power failures “in this day and age”. A UPS gives you anywhere from a few minutes to hours of battery time. The length of time is determined by the amount of wattage and the number of items plugged into the UPS. Newer models also have an additional feature that will shut down your computer properly when it detects a power interruption – this is a handy feature in the event you lose the power and you aren’t around to turn off the computer.

Not all plugs on a UPS are battery back up, the battery back up plugs are clearly marked; with the other plugs acting like a normal plug on a surge protector.

Some manufacturers, such as APC, provide warranties in the event their product fails to protect your system. With a warranty of up to $75,000 covering hardware (not data loss) it sounds impressive but for the average 1-2 computer user this really isn’t an advantage. Filing a claim for a loss of a few hundred dollars is time-consuming as it requires completing a 10 page questionnaire and the payout is based on used computer prices, not new replacement prices – a significant difference. However, a $75,000 warranty does provide some peace of mind in that it does show the company stands behind its products.

When looking for a UPS look for size, shape, (will it fit under your workspace) number of plugs (printer, internet supply, computer, monitor), and amount of wattage. The higher the wattage the longer the power supply and the higher the number of items you can plug into the battery plugs. Keep in mind, increase the number of items, and decrease the battery time. Also, and this is a biggie, if you want to be able to use both of the plugs in your wall outlet look for UPS’s with “off-set” plugs. This means that the cord is angled on the wall plug end, thereby leaving the other plug free on your outlet. Most sales associates will know what you mean when you ask for an “off-set” wall plug.

If you do lose your power and after you’ve shut down your computer, turn off the UPS (it will usually beep to tell you it’s using battery power). While the battery will recharge after minimal use, if it completely discharges there’s a chance is won’t be able to recharge. Turning it off extends its life. A UPS is meant to give you time to save and shut down, not continue working for hours. For that you need a generator, but that is another blog.
