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

I bought this just under two years ago with the main purpose of providing power for a safe shutdown of a NAS in the event of power interruption. This was my first UPS so had to do quite a bit of research into the correct capacity and compatibility with my NAS. The UPS communicates with the NAS by USB and triggers a safe shutdown. It all works seamlessly and was very easy to set up in the NAS. So far it's been needed once and worked perfectly. I also tested it by cutting the power upon installation and twice since purchase to ensure it was still working. It's compact, like an oversized load of sliced bread, it's quiet and sits under a TV. I've not noticed any noticeable difference in my energy use, which was a concern initially. The only down side is the lights on the front are a really bright deep green, I had to tape over them they were very annoying. Another annoyance, which was down to my ignorance, was I had to purchase separate adapters if I wanted to plug in something that used a regular 3 pin mains plug. These were relatively cheap but added about 10% on to the price overall. The other weird thing, only for for the first day or so was... the smell. It was absolutely honking when first switched on! I thought it was a major problem and turned it straight off but saw other reviews mentioned this so persevered and it went away on its own. The price was acceptable and has been good value considering it allowed the safe powering off my NAS during an outage, something that could have caused damage to the equipment and possibly left me unable to access work if I had been away. Very happy, would purchase again.

UPS was almost fully charged out the box. Began working immediately. Unit out the box has a strong plastic smell, just something to think about before putting it in the living room with someone with a sensitive nose. Also did not come with a power cable for the unit itself, only a C13 to c14 plug, which you can use to plug the unit into your device, but you would have to use the devices cable to charge the UPS, something to keep in mind if you don’t have a device you intend to power with the kettle style lead.

I run 3x Dell Optiplex Micro PC (65 Watts a box) and POE Switch (with WiFi access points via the POE switch). This supports most of my home automation stuff. I haven't had any long term outages so couldn't advise what the extended run time is, but for those 5-10min blips (they happen on a fairly regular basis around here) it means that all of my services are still up and running. Yes there are more advanced units out there with web management etc - but if you just want to keep the lights on, this does the trick. Its nearly silent, doesn't get warm, enough said really.

I purchased this UPS to connect to my small office server which runs 24/7. Living in a village means we are occasionally subjected to short power disconnections. A Server running 24/7 with CCTV writing to the HDD requires a stable power connection so that your HDD are not damaged by such power cuts. I didn't require anything to heavy in terms of a UPS as our power is normally restored pretty quickly. I just wanted something that would connect to my server via USB and initiate the self protection mode for the disks - the BX750MI would provide this protection for me so i placed my order. First impressions were that the UPS is fairly large. For a single 9ah battery i expected it to be a little smaller. Inside the box you get the main UPS unit and an IEC male to female kettle connection lead. Whilst this is great for built in PSU's it was of no use to me as my device using a barrel plug connection. I solved this by connecting an IEC extension lead to allow me 3 pin UK plug connections. What was super frustrating is that the package did not include a power connection cable!! How can a company sell a product that you can not even use out of the box! I didn't have a spare IEC 3 pin power lead, so this meant i had to go out and buy one to connect the device to the main power. I can not being to tell you how frustrated this made me feel! After i purchased the power lead (yes i am still super annoyed by this!) the device sprung to life. The device is very simple, providing a minimal amount of backup power for lower powered device, up to around 300W. My server uses around 45w so this was more than ample. There is no display on the UPS so you have no idea of your remaining run time load, however my QNAP recognised the device straight away when connected with the included USB cable and informed me i had around 45mins of power. There are two strips of very bright green LED's on the device which illuminate the whole room at night. You can dim these slightly by holding the power button, but they are still way to bright for my liking. You can not disable them whatsoever. Testing the UPS function worked well, it continued to power my server until reconnected to the mains supply. What was annoying was the loud buzzing that came from the unit when it was supplying power to my server. I have another UPS in my lounge and this is absolutely silent apart from the intermittent beep it makes to alert you to the power failure. The buzzing from this APC unit made me question if the device was functioning correctly and if it was safe! I also tested the load on the device after the internal batteries were charged to 100%. The UPS has an overhead of around 15w according to my energy meter. So it will increase your energy costs by connecting up this UPS, however it should only be by around a small amount. My understanding of this device is that is also uses a stepped sinewave rather than a pure one - that should be fine for most home usage scenarios, but if you have highly sensitive equipment, especially with motors connected, then you should consider spending a little more to obtain a pure sinewave UPS. Would i recommend this UPS to others? If it came with a power lead then i most probably would, it's not badly priced, and does do the job of maintaining power during a power cut. The bright LED's i can kind of live with, the buzzing noise is frustrating, but this only happens when it switches to battery power mode. I just can not get past the fact they do not include a power lead with the device! Based on this i just can not recommend this device to others! A kettle lead literally would cost this company a few pence - it's just bizarre to sell a product you can not power straight from the box?! My advice is look elsewhere... I hope that you found my review helpful

I bought the BX750MI to provide power continuity in a rural area with fairly regular, short, power glitches. The unit is covering a broadband router and a mini PC used for office automation. * NO FRIKKIN POWER LEAD. As others have pointed out. What a major irritation. Good job I checked before I went on site and fortunately I have spares, but still. Is this penny pinching? * The green vertical LED strips on the front are FUGLY and serve no purpose. Schneider: Remove the LEDs and spend the money on a power lead. I used to install up to KVA-sized APC UPSs back in the pre-Schneider days. Some with additional battery packs. Time has moved on and the current case clearly uses less metal now so the unit feels 'cheaper' than I remember, but at least that makes it lighter to lug into place. The UPS still feels solid enough and it's fairly small. "Battery not user replaceable", well I am a qualified electronics engineer so I'll be able to do that - but back in the day, you'd pop off the front, remove a metal plate, slide out the old, then in with the new. Hmmm. Cost cutting? Functionally: The unit kicks-in fine when the input power is disconnected and I didn't find the unit too noisy compared to at least one other review. Having read other reviews, I do have concerns about potential battery quality, but only time will tell. Reliability: To be confirmed. The unit is easy to setup: Read the instructions about plugging in the battery connector on the back otherwise the unit will play dead. Three stars due to not supplying a power lead, the ugly green LEDs and me now concerned having read more reviews about battery issues and early life failures. Do I feel lucky?

APC Back UPS, BX750MI (750VA) has been a solid buy for me, mainly because I needed something to protect my Home Assistant setup. My HA box kept dying every time the power tripped, and I got tired of dealing with sudden shutdowns, corrupted boot issues, and the whole recovery headache. Since plugging everything into this UPS, those brief power cuts and flickers have stopped being a problem. It kicks in quickly, keeps HA running long enough to ride out short outages, and gives me that breathing room to shut things down properly if the power stays off. It’s also reassuring to have surge protection built in, especially when the electricity is being temperamental. Setup was straightforward, it feels well-made, and it doesn’t take up loads of space. The peace of mind alone has been worth it for me. If you’ve got a small server, NAS, router, or Home Assistant setup that keeps getting knocked out by trips or short outages, this is an easy recommendation. Overall, it does exactly what I bought it for, it protects my HA and stops it from dying every time the power trips.

Now my router and home server don’t abruptly shut off when there’s a brief power cut. In terms of overheads, server went from pulling 35W without ups to 55W on average. One thing that’s very annoying is that I’ve not been able to switch off the bright green lights that’s constantly on.

bought this as a replacement for another APC UPS, which failed due to battery leakage after 3 years. so I bought a bigger unit. (I use it to back up my internet modem and alarm /phone/cameras - nominally 12W) The unit has always run warmer than I'd like and I think it as dried out the battery after just less than 2 years. So I cannot recommend this device at all. The older unit had a strange size Yuasa battery which was not available so that went for recycling as this will do. I'll try Eaton next

Silent and very good cover which looks good in an office. I have 5 APC UPS. Keep up the quality.

Reeds ervaring met het merk voor professionele doeleinden. Simpel plug & play: steek de toestellen in die je (tijdelijk) online wil houden tijdens stroompannes. Mijn NAS communiceert met dit toestel en kan automatisch -gecontroleerd- afsluiten. Ook mijn server kan ik in geval van stroompanne met deze UPS op gecontroleerde manier afsluiten.

Hat perfekt funktioniert.
