This UPS is a high quality product, but there is a high chance that your computer's power supply unit (PSU) may have a compatibility issue.

That's the problem I had when I received the unit yesterday. The computer ran for a while with a load of abut 135W shown on the UPS's LCD, which is well under the 540W rating of the UPS. All looked good for a while and then the computer stopped responding. That is not normal for my machine and it happened a number of times when powered by the UPS. It was fine with a direct connection to the mains.

After doing some research on Google, I found that this is a well known issue. Google "APC application notes" and read "Proper UPS selection for servers with active PFC power supplies", which is note number 147. That note has useful details that should be read before buying this unit.

It is now normal for PSU's to be of a type called active PFC and these may not work properly with a UPS that does not deliver a sine wave output. Note that the same issue applies to any UPS that delivers a stepped sine wave output; it is not specific to APC units.

After some further research, I found that some active PFC PSUs work up to a certain load with this type of UPS (the numbers were in the range of 250 to 300W). My computer had a solid state main drive and three large hard drives for storage and backups. I tried removing these drives to reduce the load on the PSU, which let the computer run without crashing.

The Good
I am getting nearly an hour run time on battery and the unit is quiet in use.

The Bad
It's not easy to be sure if your computer will work with this type of UPS.

If you want to avoid issues then you need one of the more expensive units with a pure sine wave output. Three stars awarded, because the product is good, but the description should point out the compatibility risk.

Model Number: BR1500GI
I have wired two trailing sockets from two of the 5 UPS protected outlets each trailing socket supplying a seperate PC setup. PCs are a pair of i72600 CPUs in intel motherboards. Two 19inch flat DELL monitors are also connected plus a BT telephone base set, two IP cameras and one adsl router. Running flat out Total power drawn is shown as 485 Watts leaving another 300 watts or so in reserve. Estimated runtime on battery is 15 to 20 minutes. Switchover during brownouts or blackouts was seemless with just a clicking sound and what sounded like a fan sound from the unit. Overload protection was tested when a 2kw vaccuum cleaner was accidentally plugged into one of my trailing sockets. The device beeped and transferred to straight through power until the vaccuum was unplugged/shut off. UPS and PCs ran on with no ill effects to any equipment. Another quality product from APC. Yes, 5 of the sockets are not on UPS but only surge protected but this is a baby UPS for home or small office use and I find 5 UPS protected sockets more than enough. My other APC unit is over 4 years old now and still going strong.

Having previously owned a smaller APC UPS unit that failed due to a life-ex battery (after many years), I went for a bigger unit this time so that I could run my large monitor and Mac through the UPS. I am very impressed with this new unit which is not much heavier than my old unit of half the power, but has far more features. The display on the front shows me exactly what my power consumption is, the state of the battery, and much more. Turning the mains on and off shows just how seamless the supply remains to my Mac, and all-in-all I am very impressed with this 'peace of mind' bit of kit which means that I no longer have to fear small power outages.

Very professional looking, quite small, and very well built. Easy to setup, clear instructions included - takes 5 mins to get up & running. It does include a couple of cables to get you up & running, but more cables will have to be purchased to utilise it fully (they are dirt cheap though!)

When I tested it, it powered my PC and NAS (and network switch) for 14 minutes, easily allowing both to shutdown gracefully. Some people have complained about it making noise, but it is absolutely silent in normal use - it emits a slight buzzing sound when running on battery power, nothing more.

Well recommended - well worth the investment to protect your equipment and data.

My initial review:

This unit looks and works well. Installation, software setup and run is so easy that is a pleasure to play with it. It has different choices for plugging in like master, controlled device and surge only. I tested it with my home PC that has x3 cores processor, two hard disks and gaming series video card. My monitor is 27'' LCD model. PowerChute Software is pleasure to work with. It is both simple and useful. It shows log, what happen in the past like blackouts, under-voltage, overvoltage and electrical noise (if some). It can show your energy usage like total kWh, cost per day and even comparison to what other activities one can do with the same energy. What I like most is the possibility to setup up silent hours or switch all sound notifications from the UPS device at all. Of course it gives you possibility to choose when to shut down (minutes on battery power). It allows to setup three levels of sensitivity regarding the power quality of the electrical input to the UPS. These are thresholds above or below certain voltage when the battery will be switched on. The display is nice and can display the current input voltage or consumption or the projected time on battery. When I simulated blackout it silently switched on and showed 11 min. battery time on its display. On computer screen a pop up that computer is running on battery now. After 6 or seven minutes a warning was displayed on the PC screen that computer is going to be hibernated and that happened. Not long enough after computer was off the unit switched off as well. Brilliant! All this in proper silent manner as I expected.

My update after several days of use:

The only drawback that I see is kind of hiss or noise that I hear when I lean over the UPS device.
