I fully trust my system to their UPS, which directly routes to my TripLite surge protector, from which all my sensitive equipment is powered.

1U and Rackmount - The battery fits perfectly in a 1U slot on my rack, and is narrow enough to work with most rails. The handles can be optionally attached if you need an extra 1/4-1/2" of thickness depending on your rail kit, allowing it to be compatible with even more kits. Front Panel LED is easy to read, not too cluttered with useless icons. The uncovered button changes the info displayed, cycling between Input Voltage, Output Voltage, Battery Run Time (Minutes), Load Capacity (in %), and Battery Capacity (in %). 6 outlets on the back panel: 4 battery/surge and 2 surge-only. There are additional ports (USB, serial, RJ-11/45), but I didn't use those, so not sure how well they work.

This is an excellent product with an easy to use interface. It is has a stylish and quality build.


Reasonable cost Small form factor




Using multiple open source platforms to write code for my college courses. Easy to configure using command lines.

- dependable - good battery life, if you discharge them periodically - simple user interface


This UPS replaced an APC Smart UPS 750 RM 2U - also a rackmount unit. The SRT1000RMXLA adds a super-functional display, power-conditioning capabilities in addition to larger battery capacity/improved runtime.

Easy set up, software install was a breeze. Works flawlessly. I have used APC for over 10 years now for my UPS and have never had a problem.

Easy setup just went to the website and grabbed the files I needed and I was up and running. I was able to power my NAS, ESXi cluster and switch with more then enough room left over.

I have used this for many years and it's still hooked to my pc now. Started with an Hp Pavilian that I added a 500W PSU to, nVidia GF9800Gtx GPU, 2 DVD+/- Dual layer/format drives, Creative SB Audigy, 2Gb Corsiar Ram, 7in1 Media card Reader, Floppy Drive and a 19" LCD Monitor. Not to mention a 5.1 A/V Surround Home theater system with all 6 speakers hooked up (if that makes a difference). I bought this cause the place I was living at the time the electric would go out constant. Paid back in the day like $160 for it. I Also had a small desktop light plugged into this thing as well. When power went out with all mentioned above hooked up, this thing would give me an easy 35 - 45 min power of all except the stereo I would turn off when power went out. Love this Batt. I still have this thing to the day hooked up and working quite well and its 4/2011 now and still going strong.

Top build quality. Good looks. Good runtime. Availability of support and parts very reassuring. Expansion slot. USB. Full time DC-DC pure sine PWM.

***An updated after several months of usage, and a change in score to 5 stars as I've learned more about the unit. Buried in the software which is run through your web browser, is a setting to turn down the sensitivity on the incoming voltage which fixes my major con of this unit for me, the unit toggling between ac and battery constantly. *** Very straight forward to setup, the units interface is fairly intuitive to use. Provided me with roughly 30min of power for 2 computers, I7 7700K with a 1080ti, and a I9 10590XE with a 3080, a boat load of SSD drives between them, lots of peripherals and 3 monitors. No blip in the computers performance when switching between battery and ac driven power. Online web interface for real time monitoring of the unit is a nice plus, can send you email reports when issues arise with the unit. Clear instructions to position the unit in it's final resting place before you connect the battery. This style battery shouldn't be moved around once it's connected.


Good battery backup at a good price

Bought because the electric work in my new house is unreliable. Until I fix my house I bought this and it has saved me from so many under voltages I almost lost count. Bonus points for saving me through two thunderstorms that killed my electricity completely. I couldn't have bought it at a better time! It gives time for how long the battery will last (depends on how much current you're drawing). Kept my computer on until the electricity came back on. I feel so relieved! Plus pure sine wave is better for your sensitive electronics such as a PC than simulated sine wave. The product feels super solid and you can connect it to your PC's usb to get a system notification icon on how long the battery will last. Amazing.
