Hardware acceptable- software unacceptable

  • Excerpt: I purchase three of the more expensive APC backups because I wanted to have the option of silencing the repeated alarm when the power went out. According to the information I read, this was possible through the use of the software.
  • Pros: Durable Construction

  • Summary: This is a very good battery backup unit, but the switch doesn't always turn it on when you push it, even though it beeps, indicating you turned it on. Very annoying. I have the same problem on another APC model, too.

Power supply Plus Benifits

Daniel O., Newegg
3 July 2015
  • Summary: Apparently someone at Newegg decided to hide their skin magizines in my box as it was being shipped out. There was a Quality assurance test slip taped to the side of the unit. Was it used? I seem to remember paying for new.
  • Pros: inappropriate material! (/BDSM) Some sort of Quality control check taped to the side of my unit. Power went out and it worked!
  • Cons: It is heavy, but then again it is a UPS unit. If you have A high speed network like me (100gb) this unit will be a bottleneck if you use it(goes down to 1GB) Unit failed to protect PC and components from a lightning strike. Network Protecting part failed, Router and NIC cards were fried.

You can't go wrong with APC back-ups

  • Excerpt: APC makes the best back-up batteries as far as I'm concerned. I only had it for several days when our power went off. I was able to continue using my desktop, monitor and wireless modem until I could save my data. It truly works when you really need it to work.
  • Pros: Compact Size, Dependable, Durable Construction, Good Warranty, Great Protection
  • Cons: None

Does what it says

J C., Newegg
22 June 2015
  • Summary: Hope it works good over time.
  • Pros: Quick ship and quick install. Although have not had extended outage, it beeps now and then to signal a drop in current. Good to know as one wouldn't know otherwise. Hard to rate 5 without experiencing an outage, and hard to rate 5 with only 4 battery protected inputs. Had to Christmas tree one to...
  • Cons: Heavy so would be expensive to return/replace/replace battery.

  • Summary: I wish someone had told me whether it had keyhole slots for vertically mounting it before I ordered, but fortunately it does. I am using these on the data/telecom service entry boards at businesses to hold power for switches and modems or routers. Works great for this and looks nice.
