CyberPower EC750G Ecologic Battery Backup & Surge Protector UPS System, 750VA/450W, 12 Outlets, ECO Mode, Compact Uninterruptible Power Supply, Black

EQUIPMENTProduct: 450VAEquipment: 2017 27” iMac | 3.4GHz i5 | 40GB Ram | 4GB graphics cardINTROI am a freelance motion graphics artist and I work from home often, so I decide to buy this battery backup system (450VA version) as a safeguard in case of a power outage, giving me to time to save and close my projects. I have a 2017 27” iMac and I searched online to find out how much power this computer uses and estimate how long it would take for my computer to shut off. I couldn’t find a definite answer so I decide to purchase and do my own testing. Of course there are many variables in figuring that out as it all depends on the usage and how much power the computer is using at the time of the outage. If you are using your computer for browsing the internet at half of the screen brightness while not watching a video or listening to music, your power consumption will be a lot less than if you were editing heavy animated graphics at full screen brightness while using the speakers.THE TESTFor my first test I unplugged the battery backup from the wall and started the timer on my phone. On the iMac I had the screen brightness 3 dots away from full brightness and I had Adobe After Effects rendering a 10 second medium complexity animation project at a third of the resolution.- When I unplugged the battery backup from the wall, I heard 2 beeps - letting me know that the system is now using the battery.- The two beeps kept repeating every 30 seconds, probably as a reminder that I was still running on battery.- At 2 mins and 40 secs I heard several beeps - I am assuming that the battery was at 50%- At 4 minutes several beeps went off and did not stop.- At 6 minutes and 35 seconds, the iMac shut off by itself.CONCLUSIONThe product seams to be of good built quality, I like that all 8 outlets are surge protected and only 4 of them are battery backed up. At about 6 minutes of power after an outage, that works perfectly for me. I don’t need to be working during a power outage and 6 minutes is plenty of time for me to save my projects and not loose any work done. For the price, that is a small price to pay for huge peace of mind. Now, if you need to be working through a power outage or if you will be using a bigger power load with more equipment using the battery’s power, I would advise for you to get a battery backup system with larger battery capacity.

I bought this because I have frequent power blips and outages where I live and one of those blew up my old system a couple years ago--even with a surge protector. I didn't need something industrial, I just needed something to last about a minute or two while my Generac kicks on. It's running my PC with no issues.I did a ton of research and was about to pull the trigger on something more expensive that can handle 650+watts (that's the power supply in my computer). But after reading some Reddit threads from people who have gaming systems that demand a lot of power are using this size. Just because your PS says 650w, it doesn't mean it's using all 650w. It just means it can handle up to 650w of installed components. My system is running an AMD Rzyen 7300 8 core processor with an onboard Nvidia graphics card. As per the Cyberpower Powerpanel Personal app, I'm using between 50 and 90w (if I'm watching videos) and I would have about an hour runtime if the power went out. I'm not a gamer, but those other people were and they didn't come close to maxing out the limit on this unit. I unplugged the UPS from the wall and my PC wasn't affected at all. This was a great investment considering I can't afford to build another new PC if the power goes out.

450VA/260W : Seems to be very nicely made and functions as intended. Not recommended for gaming machines or High end workstations. I plugged my HPZ800 Work Station with a GTX 1070 Nvidia card into the 450VA/260W battery backup and it did not like it one bit. Endlessly beeping as the work station was drawing to many amps. If you are running a standard office computer, not going to be an issue.Update:I bought the 850VA/510W and it works like a charm. Even Linux likes it! If you have a High power work station or gaming rig you won't be disappointed.

Bought this to keep my internet router and wifi hub active when the power was "blinking" out 10 times a day after a hurricane. It does solve that problem. The only reason for not getting 5 stars is that when the power went out for a longer time, the backup died after about 15 or 20 minutes. To be fair, I had the DVD player and 55" TV plugged into it.

We've been having regular brown outs or power outages. Either way, my NAS freaks out and forgets who it is. Then the NAS runs chkdsk for a week. Just as my NAS was finishing a scan from its last outage, the power went on and off about 5 times. This boogered up the NAS again. I ordered this because it works well with the NAS I have and it will also shut the NAS down safely if the power does go out. My other UPS can't do that and it needs another battery as well. Big thumbs up on this product!

UPS EC850LCD. We'll see if I need to update this or not, later. Just received unit.Good; it was around 98 percent charged, which led me to believe it is a fairly fresh and new unit.Easy enough setup using NUT in Home Assistant & Ubuntu Desktop. (With some Ai help). USB cable included for from the PC to UPS.Heavy thing. 😂 Not much else to say, tested a gracefull shutdown with scripts for home assistant OS in a VMware Workstation Pro VM, shutdown VMware and then the PC, it works via NUT and Ubuntu scripts.Home Assistant integration popped in on its own, add it and adjust IP LISTEN.Unplugged power, PC and monitor stayed on. Hefty power so far, 6% load approximately using a 24 inch monitor and HP Z1 G5 Tower Worksation. With just PC on showing 2% load.Annoying beeper. Double click power button to shut it up, looking for a permanent solution if that's not it.
