APC is the golden standard for UPS protection. You can't go wrong with purchasing one of their products. I purchased this UPS because of the Smart software that will send a shutdown command to the PC when the battery is almost dead when the power is out. Not just kill the power to your computer when the battery runs out (defeating the purpose of the UPS). This unit only has a serial port connection, not a USB one. Had this UPS included a USB connection I would have given it 5 stars.

I have an older model (HD-HTGL/R5) Buffalo Terastation network attached storage (NAS) device which has worked fine for many years except for recovery from power outages. When the house power comes back on the NAS rebuilds the RAID 5 volume and my data is not available for about a day when the rebuild is finished. The APC SC420 UPS has solved this problem. When the power goes off, the UPS shuts down the NAS. Restarting the NAS takes about a minute. The Terastation has a DB-9 connector for the UPS which is not compatible with most newer UPSs.

There is a difficulty that I have yet to undertake. I would like to UPS to shut down the NAS after a few minutes to allow me to finish using files on the NAS. The lynx operating system of the Terastation is not available (i.e., closed) to the user and therefore I am unable to use the smart software supplied with the UPS. If I take the time to figure this out, an update will be posted.

This smart UPS is intelligent enough to let you know with a series of lights whether you are protected or not, and whether you have overloaded the UPS or not. Great idea otherwise you have to become an electrical engineer trying to work out Watts, Amps, Volts etc. It also tells when it is time to renew the batteries, another guessing game over. If you wish to connect to the network - you can control it from your desktop. Well recommended.

The APC SmartUPS is a great back-up solution for individuals that want more than battery back-up. The serial or USB interface allows for detailed reports on voltage variability and other measurements. Plus, if you have many SmartUPS's, they can be centrally monitored via APCs free software (up to 5 UPS).

Nice having a piece of mind when the power blinks. We have poor power around here and it also stops power surges. it will run my PC and DSL router for about 30 minutes if need be. I have the time to back out of all my programs and shut down without losing anything.

For best performance on avoiding power sags and surges, this is the minimum APC you should look at. Don't buy anything less as they don't filter the same way. Always buy APC and always make sure it is an APC Smart-UPS.

I leave my computer on 24/7.

I frequently experience power blips. Just enough to shutdown my computer and make all of the electric digital clocks flash.

This UPS system protects me from these occurrences and if the power outage is extended for any length of time, it shuts down my computer for me.
