Works great- as advertised. APC is a quality UPS brand.
ACP Brand is always good. I have 4 in my home office (Work computer, Stable Diffusion dedicated computer, network infrastructure, and electronic music devices). Word of advice, these are not for sustained usage during an outage for a standard desktop. (Which should be obvious to people). Just keep your computer on it, and just one monitor, so if they power goes out, you can save your work and turn off the machine. Make sure non-essential items are on the non-battery-backup plugs. Works great for intermittent outages. Also, waking up in the middle of the nights to beep beep beep-- I don't have to check to see if the power is out-- (not complaining about the noise). It's calm enough to be informative yet alerting.Ver másVer menos

Good product, disappointing (Supplier) support
This is my 2nd APC UPS backup. The first is over two years old and has performed flawlessly supporting a high-end workstation. I bought this 2nd, somewhat smaller model for my office PC.I was pleased with my purchase for six weeks until the first blackout intervention due to a thunderstorm. The UPS did not survive, when the power was restored the device insisted there was a short on the output, which of course there wasn't. The total load on the output is less than 30% of the rating, but even with the load removed it still alarmed.This began a three week adventure:- Amazon does not allow a defective return-replacement (because of the batteries I assume). Beware.- APC has a 3 year warranty but their support process is agonizing. I spent several hours in chat-windows answering inane questions like 'Is it plugged in?' or 'Are you sure there is no short on the output?' At one point the agent (who was obviously multi-tasking) picked the wrong chat-window to type to another customer. That was interesting to sort out.- I finally found someone with a brain who started a swap-process. APC would send a replacement and I would return the defect.- The replacement arrived 10 days after the failure event. I installed it and everything was fine. I re-packaged the defect in the shipping box. But there was no information about where to send it.- Another week passed before I got an email with a pre-paid return label as a pdf attachment.I assume the original item was an infant-mortality so Five Stars for the product. Battery life is over 20 minutes with my load and the PowerChute software puts the system to sleep before the UPS runs dry.It's an imperfect world: screws fall out. Time will tell if this was an isolated event or a chronic problem, but up to now I am optimistic.Ver másVer menos

Tested Under (Lightning) Fire
Lightning struck 3 houses down and fried our modem through the coax line, which also caused the ethernet-in port on our router to go dead. My computer, however, was protected with the APC Back-UPS Pro 850VA and was totally isolated (thank you wi-fi!) I could hear it click over into emergency power as soon as I saw the lighting flash, so I consider this to be tested under fire.The companion software is visually bare-bones but otherwise works great with Windows 11, the app runs quietly in the background and doesn't use much of anything, and is very programmable with the UPS. For mine, if the power is out for 60 seconds, my computer is sent a command to hibernate.Maybe less important, but I hear this protecting my computer from 'dirty power' at times as well. Outside of the regular testing interval, I hear the relays click on the rare occasion the lights slightly dim as well.Unit has been in service for 3.5 years and still performs wonderfully. I like how it's incredibly quiet (UPS of old would alarm annoyingly).Ver másVer menos

Support is rudderless and the software is not great
I had a situation where there is a line voltage drop when a printer kicks on. Even with the sensitivity control turned down on the APC, it still threw an event for under-voltage and went on battery. Even getting to this point took their technician a half hour. I was guided through a collection of useless exercises. I am a software architect and I am amazed that they have no good diagnostic tools. So, the hardware is good so far, but the rest speaks for itself.Ver másVer menos

Worked when I needed it most
Bought for backup power at my cabin. Worked perfectly during a snow storm.

Never choose Amazon same day delivery!
Never choose Amazon same day delivery. I have used this option 3 times and every time I received four or more days later. Use the next day option instead and you will most likely get it on time.The APC UPS is great! EZ to install and has already saved my computer at least 4 times. My area suffers from momentary power loss where the power shuts off then return a second later. It has already cost me two computers, three video cards and one monitor in the last 6 months. I bought this to stop the damage it causes by sudden power loss then voltage spikes when power returns. Paid top dollar for surge protectors and it did no good. If you want true protection for your equipment buy this. You can download software from APC web site that allows your computer to shut down properly in the event a power failure would exceed the battery time of the UPS. Make sure you buy one that will supply enough wattage to power the equipment you plan on hooking up to it. also make sure it is rated PFC compatible as some computers require this to work correctly with a UPS.It is now the 1st of January and so far this UPS has saved my computer from 5 power losses. No lost files and no excessive wear and tear on equipment. Highly recommend this.Ver másVer menos
