This APC BR1500MS2 Back UPS PRO backs up and stabilizes the power to my network modem, router, NAS, PBX, FAX machine and VoIP interface. It also protects them from surges. Even momentary power interruptions can be a serious interruption to my wife's and my work and potentially costly. Brief utility power interruptions cause no problems on our network. During a sustained outage, the internal batteries in this UPS keep our network infrastructure running long enough for me to start our backup power generator and get it on-line. Living on a coastal island in a hurricane zone, power glitches are common. My previous UPS was a similar APC model that served me well for more than ten years before it needed another set of batteries and was on the verge of being functionally obsolete.

This is the one to get.

Works like it supposed to. With the unpredictable Kansas weather outages are pretty common. Most are just a second or two but sometimes an hour or more. I tested this unit and it lasted over two hours. I have a 900 W Cyberpower for the 42" monitor that will also last two hours. I really like the detachable control panel. I put this under a shelf on the floor and it would be pretty awkward to see it if it didn't have this feature. Since I got these we have had one short outage and the computer performed like nothing happened. Both units barely even get warm in use.

Functions as claimed...absolutely no problems which is a lot more than I can say about the backups these are replacing.

I'm in IT and have purchased 50-60 of these units in the last 3 years with no problems. No DOA's and non have failed yet. I find that 550VA is great for single workstations like Core2Duo with duel 19" LCD's.


Great. It's 100% genuine battery from APC. No fear to get a non-genuine compatible battery.

We have used these many time and always have good luck with them

Been using these in the lab and at home for twenty years. Rock solid and I don't trust my equipment to anything else.


- Great packaging, fast delivery.

- Actually WORKS AS DESCRIBED. - Completely SILENT Operation. - Excellent & Informative Display. - Compact & Easy To Set Up. - Economical & Affordable.

Been waiting for a storm to submit a review. This unit maintained my internet connection during a Tornado Warning and subsequent power outage. I love it!



-web interface for management -email alerts -can do both web interface and USB for safe shutdown of computers or NAS

For a single PC this will give you enough time to save what ever work you have before losing power. I sustained a single PC under moderate load for 30 minutes before getting eminent shut down alerts. It is currently being used to back up power for a building automation system.


Although I've only owned this for 3 weeks or so and I have yet to have a power outtage, it appears that everything is working correctly. Also, even though my graphics card reccomends at least a 650W CPU the most my system has ever used was 300W. I guess that means I can plug more things into it.

- Works as advertised, supports my mid-range PC with dual monitor setup long enough to save, close my work & shutdown when outages/fluctuations occur - power supplied to my devices plugged in remains consistent & entirely uninterrupted - Has lived through over a dozen power flickers & full on outages in my small town which is notorious for frying household appliances with our terrible power company (in southern Ontario, Canada) - Alarm when wall power is lost and UPS has kicked on can be turned off/on - Alarm, when on, is not excessively loud - the word alarm makes you think it will be screaming at you but it's comparable to a microwave button beep, probably a little bit quieter - When alarm is turned off, it still makes a very audible click when kicking on due to external power being cut off, so unless you have closed headphones or are blasting music you'll probably know the power went out if you didn't have any other indicator (like you had your lights off in your room mid-day or something) and can begin shutting your stuff off
