I upgraded from the Powertech Line Interactive 1050VA (PT-1050) to this one because after buying a new PC, whenever there was a power outage while gaming, it couldn't hold it anymore unless I was doing some light tasks (e.g. browsing).
My new PC has an 8700k processor, Sapphire 580 8GB graphics card, 16GB RAM, 750W power supply, 2 HDDs, and 1 DVD drive. I also have a 24" monitor and a 2.1 speaker system (approximately 40W) connected to the UPS.
With all of these running, even during intense gaming where the graphics card is at 100%, the UPS only reaches a maximum load of 35%-40%! I saw this load in the program that accompanies the UPS, which allows you to adjust various important functions, such as how the UPS behaves during a long power outage (e.g. shutting down the PC properly).
Overall, I am very satisfied with my purchase. I needed it because we have a power issue at home, and sometimes when multiple devices are connected, the overall power drops, which is not ideal for a PC. Also, voltage fluctuations are equally dangerous, so I didn't want to take any risks. Especially with a new PC.
As a company, I am quite satisfied with Powertech, as the change from the previous model, which I had for 3 years (replacing the battery at 2 years), was purely due to upgrading my equipment and not because of any issues. That one is now working on my family's lower-demand PC.
The truth is, it is a bit bulky in size, but personally, it doesn't bother me. It also has a fan at the back that operates in case of a power outage to help maintain the temperature. This makes the UPS completely silent during normal operation, and you only notice it when the fan starts in case of an outage.
Nevertheless, I will give it 4 stars. Firstly, for the price I bought it (140€), which I personally consider a bit expensive, and secondly, because I would have loved to have a screen to easily see useful information (you can do this through the program, but I would prefer a screen). These, of course, should not be serious reasons to discourage someone who wants to protect their equipment from purchasing this specific model. I highly recommend it!
