1.0 out of 5 stars Not Charged About this Battery.

2026-01-25    -Chris Carrigan

The APC battery arrived in a re-wrapped box and the battery was already 89% charged. It is either used or reconditioned. Having paid almost $500 for it, I expected a "new" product. Very disappointed. I won't make this mistake again.

4.0 out of 5 stars Does not perform as I thought it would.

2025-12-31    -Leeroy Jenkins

Edit: I'll leave the review up in its entirety, but it has been brought to my attention that this UPS is not 750 watts like I thought, but 500 watts. As such, I've increased the rating to 4 stars.Short version: UPS is fine, as long as you do not draw more than ~600 watts and don't want to use the software. The unit provides many features, and is a good value for performance. Switching time is great, and this unit works fine with PFC computer power supplies. Good buy if you're looking for a solid midrange UPS for a mid-range gaming computer. If you're running a high-end computer (overclocked CPU, dual graphics cards) you will want to read further to determine if this UPS is worth your money.I will begin by saying I am an abnormal use case. At the time I realized this UPS is not as capable as I thought it was, I was already outside of the return window. This isn't an issue of degradation, but one of there not being a set standard as to how to rate UPSs. At this point, I am sure you have some idea as to what my problem is, but first a little back story.I have a computer I built myself. At the time of issue I had an Intel Core I3-2105, 8GB of RAM, an overclocked EVGA sourced nVidia GTX670, and an overclocked MSI sourced nVidia GTX 560Ti with 448 Cores. This is a fairly low-power CPU paired with two graphics cards that while not power hungry, they use a nice bit of power (think sports cars as opposed to full out race cars). All of this is being powered by an 850 watt PSU (complete overkill as you'll see in a few). With the components I have, I rarely draw more than 500 watts from the wall. For me to do this, I have to fully load both (overclocked!) graphics cards as well as the CPU with artificial stress tests. In other words, in real world usage, I'm never going to use more than 500 watts. After factoring in the other items I have on the UPS (2 monitors, a 5.1 channel receiver, cell phone charger), at maximum load I will be around 575-625 watts. Shouldn't be a problem for a 750 watt UPS, right?On this day I decided I wanted to see just how effective my computer would be with folding. In case you're unaware, I'm referring to a research project by Stanford that simulates the folding of proteins and they "farm out" the work load. If you Google search "Folding@Home" you will be able to find more information. I prepare my computer for this, start up the GPU only clients, and walk away. At this time, the GPUs are under intense load and are making a racket, so I close the door to the room to limit the noise, and do other things. I return a while later to find my computer off. Figuring there must have been something overheating, I let the machine cool for a few more minutes, and begin folding again, this time watching to see where the issue was.It turns out that even though this UPS is rated at 750 watts, you cannot exceed about 600 watts before the UPS shuts off attached loads. It does not matter whether or not you are on utility power or drawing from the battery. The UPS has a cutoff point in the 600 watt range that it decides it is going to stop outputting power and will shut down. Please note during this entire time, the UPS never attempted to switch to battery power, and the power was as problem free as utility power gets. However I will grant that this is not a common load; I am drawing more power than most. I still feel that if the UPS is rated at 750 watts, it should be able to supply 750 watts, especially while still drawing power from the wall.That issue aside, this UPS performs admirably. I previously had a UPS that was a more basic model--a stepped approximation of a sine wave, standby type UPS. This UPS would cause my computer's power supply to whine whenever it was on battery power, and would not switch back to utility power whenever the power returned to normal. This UPS has neither of those problems. Due to the different types of switching technology, it also switches to battery faster, and doesn't switch as often. It also has several features in the menu system that allow you to track power quality. The PC software is not great if you're planning on using only one of these in a home environment, but makes more sense if you are planning on deploying several of these in an office type situation. I would also appreciate the option to have the UPS just let the computer shut down hard if the battery runs all the way down, but can understand why this would not be desirable. Personally, the reason I want a UPS is more to protect against brown-outs and low-voltage situations rather than black outs or complete power outages.All that said, I want to reiterate I AM NOT A TYPICAL USER. I am using the UPS in ways most people will not. I have two upper mid-range/lower-high end graphics cards. But I still feel this product should have been capable of supporting them. I think I've covered about all I can, but if you have any questions, put them in the comment/question section and I will answer them as best I can.

Perfect

5.0 out of 5 stars Works remarkably well with a back-up generator!

2026-02-01    -John C. Roberts

I have been searching for some time to find a class of UPS's that will "behave" well with my whole home generator. My experience has been that most of the lower end units constantly move on & off line when working on generator power. This quickly depletes the battery & shuts the system down. I worked with technical support of both CyberPower & TrippLite and both were of the opinion that I needed to by an "on-line" unit; despite the feedback on Amazon that these units are not only expensive but also are not designed for "home" use. After taking a look at this class of UPS I thought I would give it a try. The UPS can be configured to accept the "low quality" power from a generator to prevent it from going on & off battery power. I have just completed a generator test with the newly installed unit and the UPS worked flawlessly with my back-up generator. When I tripped the master breaker, the unit went on battery till the generator came on line, after the generator was on line, the unit never went back to battery under various fluctuating load situations. I highly recommend this UPS if one has a back-up generator!11-17-17 Update-I just bought my second unit to protect my primary home entertainment equipment (TV, DVR, etc.) because the inexpensive UPS I had hooked up to this equipment would shut down after being on generator after just a short time; it could not handle the minor power fluctuations from my generator. Anyone interested in a UPS to run with a back-up generator should consider this line of UPS...

5.0 out of 5 stars Pellet Stove Backup Power Supply

2026-02-25    -adam6979

I originally bought the APC Back-UPS XS BX1000G 1000VA Tower UPS ($125) to protect and provide emergency power for our pellet stove. Once I got it I determined with APC Tech Support help it would not be good for this purpose. So they recommended this one instead because it can handle AC Motor loads and does not change the sinewave that can damage AC Motors. This one though is a great deal more expensive and heavier. However I watched for a "Warehouse Deal" and got this for only $160.00 almost 1/2 of retail plus it included shipping. Hooked it up and it works perfect, "plug and play".For those that do not know - a pellet stove requires an exhaust fan to run in order to extract smoke to the outside. If your pellet stove is in the burn cycle and the power goes out, chances are smoke will backup in to the house. With this connected it works flawlessly and allows me to shut down the stove and not have any smoke problems. If the power outage is short term it can run the pellet stove for about 40 minutes without AC Power. There are specific systems out there that will run much longer but they are 4-5 times the money and will not power the auto igniter. With this one you don't even know it switched over... I would highly recommend it. Also if you are in a place with long term power outages you can use a generator to provide constant power to the UPS which in turn will smooth out the current and provide exactly what the stove needs. Generators have such a fluctuating current and voltage they can damage the electronics in a pellet stove (as well as any other sensitive electronics). This stops damage from happening.Also on a side note - for one money we now have our computers protected and will be protecting our TV and related electronics as well.... all around a great piece of equipment for little money!
