## Description

Review: Ideal home power backup. - Living in a rural area we experience relatively frequent power outages, often for no more than a couple of minutes, but enough to cause havoc with my media centre PC that is attached to my TV. I have used APC equipment at my workplace and it has always served me well so I decided to try one of the small home units. The BackUps 650va is indeed very small and light for a UPS. It is silent in operation and can easily be hidden away. Setting up the UPS is child's play as both Windows and OSX recognise it as soon as it is attached. The optional software is, in my opinion, the defining difference between this UPS and others. The software installed without a problem, is extremely intuitive to use and allows for all sorts of customization (that even extends to silencing audio alarms between certain times and days.) My PC is fairly powerful and draws around 200 watts in idle mode so the UPS will only run the machine for 20 minutes but that is long enough to see me through short outages and, if the power stays off for a longer period, the software safely shuts down my PC. The UPS is designed to protect computer equipment that utilize the standard PC power connector so, if you want to use it for other equipment, then you may need to buy different leads. (I have also put my Sky+ box through the UPS as it positively hates power outages but I needed to buy a 'special' lead.) IEC C14 Plug to Figure 8 Connector, 2m [Electronics ] Overall I am delighted with the look, quality and functionality of this unit and thoroughly recommend it.
Review: An excellent UPS - I have had this uninterruptible power supply (UPS) for a year now and feel that it deserves this feedback since it has proven to be very reliable. It has done everything it is supposed to do, i.e. kept my computer system operating normally after a number of power cuts giving me more than enough time to shut down without losing data or causing any malfunction. That is over 5 minutes in my case but that time will be more or less depending on how many peripherals you are powering (I have two external hard drives, an external speaker system and printer). If that is not long enough for you maybe a larger size UPS in the same range would be better for you. The build quality is very good as you might expect considering APC provides a two year warranty period which includes an additional comprehensive insurance policy against losses caused through any malfunction of the UPS. When there is a power cut it seamlessly continues supplying 230V from its battery, giving warning bleeps to alert you if you are in another room. I have contacted the manufacturer via email for information a couple of times and they have responded almost immediately with full answers through their system of customer support which I have found to be excellent. The software package (PowerChute) that comes on a CD provides a number of monitoring and setting options that will suit most users. It may not be the cheapest UPS out there but I would say it is one of the very best for the price, and when it comes to price, cheapest is not always the most reliable, which I have found this UPS to be.

## Questions & Answers

**Q: If there is a power cut how long would this be able to run a normal wireless router? Thanks**
A: The batteries, judging from the replacement items are around 90 VAh, so for a 15, 20? W router I would budget for at least 4 hours.

**Q: Hi, Is it only the protection role the item provides to the equipments? Does it redress the current flow in pure sine wave form?**
A: IT keeps my QNAP NAS box running for a pre-defined period. I set the USB UPS mode on my NAS box to initiate a shut down if power was not resumed within 1 minute to protect against data loss (in cache memory etc)

**Q: Does the software run on linux? (via wine or virtualbox if necessary) please only answer if you know for certain. thank you.**
A: The APCUPSD daemon will monitor this device over a USB connection.

You will want to run this service 24/7 on the host Linux OS in order to be able to shutdown your computer cleanly if the battery becomes very low.

There is a bit of configuration to be done but it's well documented. I've been running other APC models (Smart UPS which provide more information to APCUPSD) but this one is supported.

**Q: Can this item be used on my 2014 imac please?  i read on some of the answers on here that this device is not good for newer imacs**
A: Dear Valued Customer,

Good day.

I understand that you want to know if BK650EI can be used to support your iMac 2014. Let me help you with this.

Most of the modern PCs utilize Power Factor Corrected (PFC) power supplies. Kindly be informed that BK650EI is not a suitable UPS for loads with active PFC. Reason behind is that the transfer time of this UPS is long enough to remove power from the PFC power supply, resulting in a momentary inrush of the PFC which may cause a potential overload condition or dropped load. To know more about this, please follow the link below:

You may want to use an SMT750I instead.

If you need further information or advise on this, please get in touch with our support team at 0800 2799 254 (UK)  1890 272877 (Ireland) or by completing a webform as found in our website: http://www.apc.com/support/contact/ask_apc.cfm.

### ⭐ Old stock with dead batteries
*by N***L on 3 March 2025*

I got these devices at beginning of December 2024. Just finished my computer room and plugged them in and both have the lights flashing and bleeping stating battery needs to be replaced. As it is on both of them this is not a one-off case. This is old stock with old batteries. It would cost a fortune to send these back as they are very heavy. I am trying to contact vendor to request free replacement batteries. Anyone know how to contact the Vendor?
