BX750MI

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

Do like APC models, have 4 now, but this was to replace one that stopped charging the battery, so this is larger in backup power and size. But does what it says. Takes a week or so for the burn in smell to go, but no issue.

When the unit gets close to the fan temperature, it will on and off the fan repeatedly in the space of 2 seconds which is incredibly annoying on a warm day. It wouldn't have broke the bank for the fan to have been voltage, or PWM controlled, but no, this is on/off on *exactly* the same temperature (instead of on at 25C and off at 19C like any normal designer would have implemented). Nope these guys have to be extra special and turned their design skills up to 9000 for the most annoying temperature controlled fan ever. Other than that it seems to work ok.

The good bits, It has software to monitor it and allow you to see battery quality. Also will power down the pc when battery gets too low. The bad bit. The UPS is MASSIVE in size. I ran a test from 100% to 6% where it would hibernate the PC. It's a mini PC pulling only 39watts of the rated up to 650w this can deliver. It last 52min 22seconds no where near the 88 mins it says as 39watts only 6% of it max power output but has lost 40% of its rated max run time!!!. This for me will be fine as I need to protect a small PC server from power cuts but if it was something pulling more power I would see this as very disapointing for it's size. So to sum up, Design wise its very big for not alot of capacity, Functions well but wont last long if under any real load, No wall to UPS power cable. Battery capacity is lacking needs a bigger Ah battery and I'm sure theres enough space inside for about 2 more than it has!!

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.

Bought this 2 years ago to serve as a battery backup for my router, Wi-Fi AP and to give my NAS some security so it could shut down safely. It has a USB port which works well with the Synology NAS without any real configuration, whereas other UPS' I was looking at at the same price did not. I calculated that it could potentially run those devices for 1-2 hours without too much issue. Otherwise the unit is fairly basic, and it uses IEC connectors so you will potentially need to buy new cables and so on to actually connect to it. The BX950MI I used has several battery backup outlets and a few merely surge protected ones, but that's fine, and the relatively small size of the unit happened to fit in well with my network setup. So far, all good, and for the money, a decent unit. Where I've deducted stars is because after 22 months, the battery unit on mine is completely dead, which is much sooner than expected - I expected 3-5 years before needing replacement. This is a shame, but what really frustrated me is the unit did not make this easy to understand. One day I saw the lights on the unit were constantly flashing, but there was no audible tone, which didn't match the "replace battery" warning in the manual. I experimented with it to try and resolve whatever issue it was over the course of a full evening, where the warnings were not clear, until it eventually settled on the replace battery error, which is the flashing light AND a continuous tone. Problem was I could not get the tone to silence using the physical controls, and it only stopped after bringing down a laptop and installing the associated desktop app and connecting via USB. Here in fairness in the software it clearly indicated the battery needed replacing, but it was frustrating and highlighted how clunky the controls are on this particular series. Overall, it does what is says, but the whole point of a UPS is to avoid damage and have less downtime, and I've had more downtime trying to understand the issues it was having than I would have had by not having it at all.

I've been using APC for the last 25+ years and their products have never let me down. Living out in the sticks our mains supply is prone to short power cuts, so we've purchased a couple of these for our desktop computers. They do the job, really easy to set up and use, I like the ability to turn off the sounder on the fly. Good value for money too.

Have 2 of these, uze 1 as a back up to my UGreen 6800 Pro NAS and when I plugged in the included USB cable it was immediatly and correctly identified. The otherone backs up my routers and switches, Both working flawlessly.

mycket bra UPS. Endast nakdel ( som nsätan med alla APC UPS ) är att den lukta i flera dagar innan det läggs av.

Works great with my NAS - automatic safe shutdown when power fails

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.
