Saves My Hard Work

ANOYMOUS2014, Amazon
13 January 2014
  • Summary: 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.

A Life Saver

Chuck, APC
9 November 2013
  • Summary: A little tricky to connect the battery the first time, but well worth the effort. I have my computer, monitor, and printer connected. Several times I have had brief power failures and my Smart-UPS kicked in smoothly and saved all my work. Well worth the investment in peace of mind and saved work.

Read all specs before buying

Jeff, APC
18 November 2012
  • Summary: The UPS is working fine and was plug and play. The serial interface was unexpected and worthless. The last 6 APC UPS I have purchased over the years always came with a USB connection. Not this one, my server does not have a serial connection.

Good UPS

Gary A. Olson, Amazon
2 September 2012
  • Summary: 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.

UPS for Terastation

Richard Nelson, Amazon
8 December 2011
  • Summary: 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.

Minimum level APC you should buy

D. Gull, Amazon
14 November 2011
  • Summary: 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.

Bought four and they are ALL dead

6 May 2011
  • Summary: Of course, that wasn't until long after I could return them to Amazon. I'm still trying to find the time to call APC about these. I bet mine were refurbished and not advertised that way. Every single one of the four I bought have died!!!???
