APCBack UPS - BX750MI - UPS 750VA Battery Backup & Surge Protector, Backup Battery With AVR, Dataline Protection, Uniterruptible Power Supply BX750MI

It works well. but only for about 2 years.Pc & hub

Bought this to provide backup power for my home server and CCTV system. Luckily not had to use it in anger yet but tested by pulling the power and kept everything running in the interim, enough time for my server to have a graceful shutdown and for CCTV to catch anyone that might have been interfering.Build quality is decent, seems sturdy and reliable. Doesn't emit any more noise than my home server already is so already keeping the levels down. Fits comfortbaly alongside my server on the shelf i've got them on so doesn't take up too much room.I can't speak to how long max this would keep things powered for, i think the estimate may have been about 10 minutes, but for the purposes of what I need, that is more than enough.Overall great unit for not an outlandish price, so I would say a great buy.

I have bought a LOT of UPS's over the years, I lived in Shetland in one of the more rural spots where you would get power outages for short periods on average once every month or so..SO I tended to have a UPS on the Boiler, on the PC setup and the broadband router and the most important part of the UPS for me was having a MUTE button on the front so I could carry on during power disruptions without the UPS beeping every 30 seconds driving me insane...So recently when I was looking for a decent UPS for my PC setup I found that the Mute buttons seem to have disappeared from a LOT of APC UPS's and I trust APC... but looking at a couple of Youtube videos I saw a guy configure the "mute" button by connecting the USB cable and installing the powerchute software and then silencing the unit.Upshot is I took a risk, ordered the 1600va version of this "easy" UPS, installed that daft powerchute software and configured it NOT to beep. and found that it IS a good UPS (then uninstalled the powerchute software.. and it is still a silent UPS).Other then that it is a decent unit, It does NOT come with a kettle lead of itself.. so make sure you have a spare! and it comes with a single IEC female to male adaptor cable, so you will need more of those to... added expense, but this is a cheaper home consumer unit to I was expecting that.UPDATE EDIT 27/04/2024 - Saturday morning the UPS battery self-test failed.. the unit squealed a constant tone.. until I re-installed the powerchute software and muted the alarm... the results of the dianostics? - replace the battery (replace cartridge code ending 147), can UPS send me a replacement.. no... does ANYONE in the UK stock the replacement battery?.. NO... just a couple of replacements on eBay from dodgy sounding traders wanting £120 plus postage..What happened APC?!? I used to trust you guys! I got 10 years out of Backup UPS units before now, and I get 25 months from this new one... and even though it is muted... again.. it flashes it's light CONSTANTLY distracting me all the time..I'm buying a unit from Powercool... as they could NOT be worse then this thing...

I got this to power my QNAP NAS in case the power goes out. From best to worst- it looks quite nice and as a unit for sitting under a tv, doesn't stand out but the light is a little bright.- USB support is excellent and doesn't need anything special to work out of the box. the qnap saw it straight away and started using it plus my windows pc saw the battery as soon as i plugged it in and started acting like a laptop, which is excellent and allows you some very special power management based on percent of charge and if the power goes off.- When the power goes out, while it isn't full sine, it's not quite as aggressive as some of the other units i've used. you can still hear that it's not full sine but it doesn't sound like it's wringing the neck of the devices connected to it.- Run time is acceptable, i've gotten 10 minutes out of it with more to spare (with about 200w load) and for my use that's all i need, i can't comment on full run time but as this unit uses lead acid batteries i wouldn't ever recommend running them completely flat as that will damage them.- This unit does run quite warm, the AVR circutry seems to give off a fair bit of heat so if you're putting it in a cupboard make sure that there's a fan blowing some air over the unit, i don't think i'd like to see what would happen if the lead acid batteries start boiling.and the worst- You can't change the batteries yourself, i'm sure you can order the replacements but the actual unit is designed in such a way that it's not trivial to replace the batteries, which in my eyes is just stupid. for something that will last max 3 years, that's a poor move from APC and doesn't inspire confidence. for me that's not a big thing as i will be upgrading to another full sine unit in the future but that still leaves a bad taste in my mouth. i wish i knew this before i brought the unit because it's just as important to be able to service the unit as is the quality of how it works.Overall, you'll be well served by the unit for low priority stuff and the USB support is excellent, just a shame about the batteries.
