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.

Purchased this to protect my expensive gaming PC. So far I've had this ups system for roughly 9 months. The first one had a cracked screen (still worked, but had a crack) I returned it for another and have been pulling my power through the UPS system since.This backup has saved my computer from two live (my PC was on and running) power outages. It has also saved it from surges where we lost power and it came back on numerous times. I've never had an issue of it not powering my PC long enough to shut it down properly. This thing has been a small investment to save a much larger one, and it has, everytime.It comes with a printer looking cord (USB-A to USB-Type B) to connect from the PC to the UPS to help communication when the the power fails and the support from the UPS is need.Connecting the two has features. You can double click the "power assist" in your system tray. When it opens you see the Vertiv Power Assist program. It shows the information in the pictures.The size is about 11 1/6 inches tall about 4 inches wide, and about 17.5 inches long.I would definitely buy another if I had the need as it's saved my PC numerous times. I would recommend this for everyone who is looking for sufficient power in the form of an UPS system.

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.

This item is NOT warranted for home use by the manufacturer.No instructions in the box.Surge protection level is very low compared to most protectors purchased separately.I found it on sale.

Leaving a low review to catch people's attention so they aren't smacked in the face like I was.TLDR: Does not work with open-source UPS monitoring tools like NUT, etc. Requires proprietary software by Liebert.I made the assumption that a UPS made by a company known for high-end power backup solutions, and that had a USB port, would be able to be managed by something other than proprietary software. I have been able to connect my previous APC and Cyberpower UPSs directly to my NAS (most critical system needing to identify power outages) and then use the NUT server there to communicate to the other systems in my home network (variety of Linux & windows servers) to shut down when power backup levels got low. This UPS is not detected by my NAS and appears to only be able to be monitored by it's own proprietary software. I failed to realize this until after my return window had closed (shame on me).Further research shows that many users have difficulty using any monitoring tools for this unit. To make matters worse, you have to create an account and enter personal info for the honor of downloading this software?!?! Liebert is now blacklisted for my use and recommendations.

I have an old school Dell T710 and a linux machine on this product and had about 6 power blips in an hour and they all maintained continuity on the battery powered side. There is another side which isn't battery powered but have a surge protector. Plug all your stuff in accordingly if you are a domestic consumer with which ones need a constant power to either power it down gracefully, like a server, or just a surge protector and lose power, like a monitor, etc. Decide which of the two options you have. Get it!

Solid UPS, good specs, well build. Not much else to say, for what it is, its a good one. Runtimes are great, perfect for a home office or smaller power need areas. I'm able to run quite a bit of home office gear from this and it handles it like a champ. Happy with the brand/model and would buy again.
