In Battery Backup (UPS)

Arrived early. Works well.

Operated exactly as advertised. This review unit arrived with excellent timing. The day after I installed it the power here went out for over an hour with several outages the following week! Not only did the BU 600 keep my cable modem, gigabit switch and a high end router running without missing a beat, I was even able to keep my phone charging. Estimated run time with the new battery and minimalist load was 3 hours+. Of course age reduces the battery capacity, but if you use this product in your server room, it will keep your web connections and routers running like nothing happened for at least 60+ minutes Management software is a free download. The unit was detected on my win7/64 laptop USB and windows drivers installed, and then I installed the APC software. No eyebrow raisers there. Wall mounting holes a nice touch. USB charge port @ 1.5amps shows engineers are listening to customers. I'm seeing this all over the business lately. I just bought a nice desk lamp that has a USB charge port on it.

Easy to set up and use.

Downloadable software for enhanced experience. 3 year warranty (excluding battery) Minimal footprint High capacity for residential use cases. User replaceable battery Easy to understand front panel controls Plug and play & Advanced setups Easy to understand labeling on back of unit

Pure Sine Wave power supply doesn't put unnecessary stress on modern power supplies. This product also takes up a minimal amount of space and shows up as a battery backup in OS X without any software or drivers. Here is what I have plugged into this UPS with only one bar on the load indicator: Mac Mini 2012 server (quad i7 with two HDD) and IPS monitor External thunderbolt with 3 Constellation ES.3 drives QNAP 2-bay NAS DSL Modem Airport Extreme

Set up easy, works as expected.

Able to run my gaming computer at max potential with my monitor for 3 minutes or more, enough to withstand a electric blink.

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

It's been plugged in and connected at all outlets for about 3 years and I Haven't needed to replace it yet, so I'm buying another one right now. For me, that's about the best pro there is. The unit has a protective cover over the power button, to me that's worth the price of the unit right there...

I work in music recording/mixing studio environments and am extremely fussy about equipment that generates noise. I'm pleased to say that after several months of continuous use, this Li-Ion APC rack unit met and possibly exceeded expectations. When in ideal conditions, the unit is literally silent. No fan noise, no hum, no buzz. The only time noise has been observed is either when the unit is charging (due to a power failure) where very minimal self-noise is inevitable, or in an under-voltage condition (117V or under) where the internal circuitry activates in order to boost the output voltage. In comparison to APC's own legacy units (ie: 2U 750VA-1500VA lead acid monsters) which I have been using for over 15 years - they had frequent noticeable cooling fan noise, and could produce undesirable self-noise when approaching maximum load. And anecdotally, I have had one or two units fail over the years and drop the load.

Been waiting for a storm to submit a review. This unit maintained my internet connection during a Tornado Warning and subsequent power outage. I love it!

Works great. Put my computer to sleep to go out for the night, power went out, came back and had time to shut it off and then plugged my desk lamp into it to have some light for a time.

- 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

Seems very well built. Great design. I love the display that shows power consumption for your computer, as well as estimated time on battery back up.

-Easy to set up and get going. -The monitoring app on the computer is very useful -The UPS itself has a very clean look to it. -Comes with a 90 degree plug, to get behind a desk or piece of furniture.

Lots Of Outlets LCD Screen for basic input and info. USB Connection for Software Control Good duration

Can handle demanding load Easy setup Good customer support Easy tracking of power usage

My CP850PFCLCD works perfect. I've connected to it 2 computers (one for games), printer, charges, laptop. It works 5 min. through battery with almost full load. It's OK. When power cut the UPS switches to battery very well. No any sound from UPS. You can install it next to your bed and sleep ).
