Do I Need an Uninterruptible Power Supply?

Do I Need an Uninterruptible Power Supply (UPS)? I’m beginning to think that I really do…

For a lot of years, I kept UPS’s supplying power to all of my family’s computers. I was concerned over power outages and their impacts on the data structure on my hard drives.

I wasn’t concerned with power outages causing damage to the computers themselves, or even to the physical hard drives. I was concerned over the possibility of data corruption, especially if the computer was writing to the drive’s data structure table at the time the power went
out.

In those days, I ran Norton Utilities on my computers and let them automatically defragment during the night on one nights a week. For my home theater PC, not only did I let it defragment twice a week during the night, I also wanted to give it a chance to keep running through a short power outage.

One thought on “Do I Need an Uninterruptible Power Supply?

  1. Terry,
    No, you do not need a UPS. During a storm severe enough to kill the power, you shouldn’t be online anyway. I suspect that the numberof “saves” by a UPS (in the US, not Uganda) are equivalent to the number of shark-bite deaths.

    A huge waste of money and resources.
