Liebert PSA5 500VA UPS, 10-Outlets, Black (PSA5-500MT120)

Weather frequently causes power fluctuation and outages. Sometimes a short blip, other times for an hour or longer which is where this UPS comes in handy. This is less expensive than others in this power range due in part to the fact that it is not a true sine wave power source. That being said a simulated sine wave unit like this is perfect for office and computer needs, even gaming. I bought this to replace an old unit (different brand) that failed.When I unpacked this new unit it came with a coax cable, USB cable and a phone line cable. Each of these permit circuit surge protection to a cable TV line, computer network line and then the USB plugs into my computer to permit monitoring and planned PC shut down should power fail to allow smooth closing of programs and saving of data.For safety reasons and to keep batteries fresh the unit ships with one battery terminal disconnected. It is necessary to open the bottom of the case requiring a Phillips screwdriver. Once open you slide the battery out, pull the tucked-in cable and then slip it on to the only battery terminal without a wire. Very simple and quick. Pop the battery back in, screw the cover on and plug into the wall.The unit powered up immediately and showed a graph on the display indicating the battery has a full charge which is comforting. The display shows Battery Charge, AC Input indicating it is plugged in to a live power source, output voltage and a bar graph indicating the power load from components that are plugged in.On the front of the panel are two USB charging ports where you can plug in cell phones or tablets etc. The rear power sockets are arranged with five battery backup & surge protected plugs on the left and five surge protected only plugs on the right. On each side there is a single plug socket moved sufficiently away from the other four to permit a wide power brick to be plugged in.I like the fact that the lighted display panel turns off after a few seconds, so the glare is not present all of the time. The middle button on the front of the unit turns the display back on.Within an hour of installing this new unit my power went off for a minute! My computer and display never flickered and I did not lose any of the work in progress whereas in the past my PC would immediately shut down with just the slightest power outage of even a second. My network local five port switch is plugged into the UPS and likewise did no lose power or signal.I should note that this takes standard UPS batteries which can be replaced by the user & the device will alert when the batteries are beginning to fail. My computers stay powered on 24X7 and I generally get a couple years life out of these batteries before they require replacing.Another point in favor of this over an older very expensive name brand UPS is the fact that the noise level is very quiet! I have three 1500va units from three different brands in the same room and the most expensive UPS is noisy with the fan always running. (Yes, I cleaned out the unit with an air hose to see if that would reduce the noise - no help!)If you find this review of any use please mark it as helpful.

I use a Sony 65" TV monitor (150 watts), NVIDIA 3080 GPU PC (400 watts idle, more while gaming), Sony surround receiver (50 watts) and cable modem (15 watts) with the wattage estimated. So I am using 3/4 of the 900 watt rating. I get about 8-10 minutes with everything on during a power outage, your milage may vary. I love this! So many extra features like: 1. Outlet power stability 2. Outlet power wiring check (checks to make sure its wired correctly) 3. Brownout protection 4. Displays Minutes until battery is drained 5. Battery level 6. Power draw from the unit in watts (Max 900 watts so you cant use an electric heater, haha) 7. BEEP mute button (THANK YOU) 8. Cable modem protection (surge from the cable) 9. USB protection. 10. 10 outlets (5 for battery) 2 are separated for wider plugs... on and on it goes. I had a dinky 650VA on my rig, WORTHLESS, my PC alone would drain that in 30 seconds. I spent $40 more and got this one. Easy connection out of the box. Comes charged, some fan noise when on battery or when I am gaming, which is fine. Works perfect. This thing is super heavy, Haha (Definitely not lithium which reduces fire risk if you ask me.) Great price you will save about $50 over other brands so that is a bonus! HIGHLY RECOMMEND Yes I am an actual customer, no I didn't receive a free one to review, nor do i work for the company. I just like the product.

Great UPS that hold its charge well, the price was reasonable and saved me a trip to MicroCenter for one of the same quality. I can get about 30 minutes or so and it stabilizes the power to a NVR for some camera's. I definitely would buy again.

Bought this when an APC 1500 decided to give me the dreaded “F02” error. I researched UPS devices and it seems this company makes pretty good and reliable ones, even more so than APC. I have only had it for a few days, so it is still early to determine if it is a good UPS or not. I will say it comes with a great piece of software that you can install on your Mac or Windows PC to monitor the UPS and help shut down your PC. It can also send you notifications for events such as going into battery power, power being restored, etc. I will also say that the software , while relatively simple , is easy to use and does not feel unfinished or clunky. What I did not like about the software is that you MUST create an account on their website in order to download it. Not cool considering it is for many users an important feature, and one of the main selling points of any UPS if you plan to use it mainly to protect computer equipment. You should not have to jump through those types of hoops in order to obtain access to something you are literally paying for.As for the device itself, it feels well built and I really like the fact that you can access the battery compartment from the front of the unit and not the sides or back as most others do. My only issue with that is that it is WELL concealed and initially could not find how to access it. It also has an LCD display that gives useful information to the user, as well as 2 USB ports in the front to charge devices, and another in the back (this last one to connect to a PC so it can monitor the battery and status of the UPS. )All in all it seems like a capable and reliable UPS. I hope that it lives up to the hype and provides me with years of reliable protection. However only time will tell. Personally, the reason why I did not give it 5 stars is the unnecessary gatekeeping of the monitoring software.
