In Battery Backup (UPS)

For just a little more money than an APC (or quite more for other brands), you can get this Cyber Power with Pure Sine Wave (so you can daisy chain smaller UPSes after it) that also has a port for an SNMP card, so you can shutdown other computers and servers on your network when the power goes out.

Arrived early and is an addon to the six other APC UPS that I have on my computers.

Kinda small and not too heavy plenty of outlets for my use case good battery life for the price

10 outlets [5 surge = 5 battery back up]. Ease of use & read on screen features. Easy swap batteries.

Best part of this UPS is the LCD display. It has a pocketful of vitals that it can display. I leave it set to Output (in wattage) to keep an eye on my power usage. It has a nice back light that can be seen day or night.

Affordable and reliable.

- This protects my RTX 3090 machine quite well - I've used APC products almost exclusively in IT for nearly 2 decades and never had any significant performance issues with them - This is the first time I've purchased a Sine Wave product, but the reviews and the science behind it convinced me to spend the extra 10-20% over a "regular" backup unit

These when only loaded with vital electronics give you plenty of time to shut them down properly in any power flicker or outage. I have multiple APCBN450M throughout my home for the cable boxes, computers, modems, routers...anythign that needs power until i can properly shut everything down.

Ok, to get this out of the way--ONE button does everything. Not the most convenient thing for consumers to do but simplifies things for the maker of the product except when people call them and go "blah blah, how do I do this or dat?" The instructions come with it on how to set settings though. Voltage trip range could be set to sensitive, normal, or high. I left it on normal, which is preset, and it tripped once within a week--I heard a click from the unit, which means it activated. Also, audio alarm could be disabled (or couple other options as to when it would activate), all of which also is set by one button.. meh. You have to hold button for so long, blah, do so long of a press blah, blah blah... meh. Green power LED is very nice looking but too bright for bedrooms, so I had to put a sticky note paper over it and paint that area with a black permanent marker (in reverse order) to keep that light from shining brightly in the room. Overall: it is a very nice polished looking product for a reasonable price.

This unit has everything I wanted in a small form factor and functionally has met all my expectations.

So far so good. The item works great. it has an APPLEESQUES look and has the plugs all on one side.

I've read all the previous comments and when the APC arrived I was a little concerned regarding noise. Well after three months, I can hear nothing and the PAC sits about two feet away. The mfgr date was FEb/18 so that may help. The system has operated exactly as advertised and was super easy to install and use. It has been quietly doing its job since I got it and even though I have had 3 "Events" I did not know it until I looked at the display.

I have this UPS for more than 3 years. One day battery died on it. I took it apart and using heavy gauge speaker wire (gauge #2 for 200 Amps) connected to a large external sealed acid battery that I have for solar system. Now, this UPS can have more than 2 hours standby power when we had power failure last year.

- Short Rack Mount Depth - Quiet Unit - Good Looking Design - Synology NAS Compatible

Small and works great for the modem and router and other small power use.
