BX1600MI

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’ve been using the APC UPS units for a while now and bought this just for my NAS. It runs silently and switches over quickly when the power goes out. I tested it a few times. Setup was easy, and it works well with my NAS (QNAP) which recognized it without any setting up. Overall, it’s a good backup solution.

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

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.

Good budget UPS for my home network rack. Fits in my 600mm deep cab with the help of se right -angle cables (not supplied).Connects to QNAP NAS over USB without problems to allow it to gracefully shut down in the event of power failure.There is a review saying the battery is not replaceable but the APC website states a part number of RBC17 as a replacement battery so I think this is an error.
