APC Smart-UPS SMX1500RM2U X 1200W/1500VA LCD 120V 2U/Tower UPS System Review

I was getting frequent 5-10 second brown outs in my community and it was causing havoc with my mirrored RAID disk array when my PC would loose power; would take 3 hours to rebuild and verify data integrity. My PC has a newer Active PFC power supply and would not work with my older UPS which did not output a pure sine wave. I also usually have one or two other dedicated servers I use for software development.
Did some research and settled on this APC UPS. The UPS has worked flawlessly. Keeping all my expensive servers online during the brown outs and saving a ton of time from the RAID verify/rebuilds that I was suffering from.
This unit comes out of the box setup as a rack mountable UPS, but the conversion to stand-up tower mode is very easy to do. Just be aware that this thing is REAL heavy and requires you to flip it around a bit to do the conversion. I ended up with a couple of bruises from resting the unit on my legs. No special power outlets are required. This unit uses the normal household plugs.
I have a constant 300-400 watt power requirement with my main PC on; 1200 watt power supply, 4 hard disks, ATI 5800 series graphics card. If I turn on my other two servers I have a 800 watt drain with all 3 computers on. UPS reports 40 minutes of stand-by power if I just use my main PC. It reports 22 minutes of standy-by power if I have all 3 computers running. The front panel LCD display reports a lot of information including current watt usage, stand-by power time, etc...

To the above Reviewer... All you had to do is just take the 20 AMP plug off and put a 15 AMP plug on. Sure, you can not use the full load capacity but your run time will be great. I modded my own Smart UPA 2200VA over 7 years ago. I am on my second set of batteries with this thing. It still runs stable... Very few pieces of man-made equipment can you say this about. So do not let the plug deter you... or others. Plus it has full sine-wave output... not stepped sine-wave. For example with a stepped sine-wave output, on BATTERY POWER alone, if you plug a florescent bulb into it the bulb would turn on and off, if you were using a regular light bulb you might see it go dim/bright/dim/bright. The stepped sine wave output is a approximation of AC (alternating current) but the sine wave is virtually identical to the power that comes out of the wall. Sine Wave output requires more expensive electronics.

I've been using APC products for 15 years, and remain a devoted user because their UPS's WORK. Our applications are primarily in the field of professional audio. Our consoles, amps and electronic equipment NEVER need servicing due to power fluxuation related damage. Use one of these big 3000VA units for a 30A circuit, and it just works -- you forget about it until the lights blink! An entire control room runs off of one unit, and we've not had any difficulties in my 12 years working in it. Plus, we're in Florida, lightning strike capital of the US!
Because the product description provided above does not tell much, I've included the summary from APC's web site:
[...]

APC BACK-UPS RS BR1500 1500VA/865W UPS System Review

APC BACK-UPS RS BR1500 1500VA/865W UPS System
Average Reviews:

(More customer reviews)
This item is BR1500, which also called RS model vs. the BX1500 called XS models. External battery BR24BP can be used for both BR1500 and BX1500. The capability to connect external battery is great, since that can help reduce the downtime when California experiencing "rolling black" in the summer.
There are basically 2 differences between the Back-UPS RS(BR1500) and the Back-UPS XS (BX1500) models besides their names.1. The Back-UPS RS models have both 1-line 2-wire phone/fax/modem data-line protection and 10/100base-T ethernet protection, where as the Back-UPS XS models only has 1-line 2-wire phone/fax/modem protection.
2. The Back-UPS RS models have both Boost* and Trim** as features of Automatic Voltage Regulation (AVR), where as the Back-UPS XS only has Boost. When the input voltage increases above the high transfer point of a Back-UPS XS model it will only go to battery.*AVR Boost: The UPS is compensating for a low utility voltage. While the UPS can run in this mode indefinitely without any negative impact on the UPS, the circuit should be checked by a qualified electrician if the utility voltage is consistently low.
**AVR Trim: The UPS is compensating for a high utility voltage. While the UPS can run in this mode indefinitely without any negative impact on the UPS, the circuit should be checked by a qualified electrician if the utility voltage is consistently high.
BX1500 does not have the AVR trim feature, when AC line voltage is higher than spec, it will switch over the battery power till the line voltage drops into the spec range.
Please note this is called "backup UPS", not the "smart UPS" line. Backup UPS does not produce pure sine wave. When power lost, it will take some milli-seconds to switch over to battery power. "Smart-UPS" produces sine wave and the output AC was from DC source all the time. When AC input lost, the AC output will not have any interrupt.
For most computers, the "backup-UPS" is good enough, since the power supply inside PC always have capacitors that can hold for about 100MS or longer. When "backup-UPS" switched over in about 20MS, the computer will continue operates without much impact. But for A/V equipment, this may be an issue, especially the output is not pure sine wave. I would not recommend use this UPS for A/V equipment.

We have a few of this UPS. They are pretty reliable, compared to those APC brand similar size UPS. The battery in this unit can last 10 minutes with load. After the original battery dead 3 years later, I open the battery door on the back, connect the battery wires to a large 50AH 12V Sealed Lead Acid Battery originally for solar power use.
This UPS is able to charge up the big battery -- it took days, but working great when AC lost -- this 50AH large battery will last few hours, instead if few minutes for two of our servers.
Do not use the regular lead acid car battery. They have different charge characters. Make sure use sealed lead acid batter, you will be pleased.

As noted in prior reviews, it is a little loud (fan noise) however, I found that after a while I don't even notice it. As to function, it has responded flawlessly to several brownouts / short interruptions in power. I have a Dell Studio XPS purchased at the beginning of 2010 and found out the hard way that the regular UPS I had (TrippLite Smart1500LCD SmartPro UPS) would not function due to the requirements of the power supply in my new PC. I read several articles about replacing the power suppply to overcome these problems, but decided that the wisest choice was to replace the UPS with one that provided true sine wave output that my PC expected. I have not been disappointed with my selection. I moved the old Smart1500LCD to one of my other PC's with less demanding power supply expectations, so I don't feel I wasted my prior investment.

Average Reviews:

Purchased 2 of these for our small office servers and other electronics in the server closet. Observations:
- It plugs into 110 volt outlet, but it's a special type of plug (unlike the typical three-prong plug)!
- They are heavy. About 120 pounds per unit. Get help getting these out of the box.
- They only take up 2U rack space, which is great as they don't take up much real estate.
- Due to their weight, you probably want to put them at the bottom of your rack.
- You can remove the 40 pound battery pack out of the UPS (as recommended in the instructions), install the UPS shell, and then reinstall the battery.
- The front bezel is removed when the UPS is delivered to you.
- The UPS comes with mounting screws and brackets.
- The battery pack slides into an opening on the left side of the UPS, and the plug that connects to the battery is in the front, making future battery changes effortless.
- The included software works well. After installing the software Agents, the APC Server software recognized both units and reported on their vital stats. The two units were connected to two different physical servers.
- Build quality is good.
- The off button is slightly recessed, thus avoiding accidental turn-off of the UPS.
I have used APC UPSs for many many years, and trusted my clients' businesses with them (when I worked a different profession). Now I trust my business with them.

This is one HEAVY UPS. Make no mistake, this is not really intended for home use. It is incredibly user friendly, except the weight. The software is great! The only real downside is when the unit looses power, the fans that kick on are more than a little noisy... but they only come turn on when it looses power, so that's a pretty small downside... Oh, and only 4 of the outlets are back-up outlets. The other 4 are surge protected only. All in all, the unit is great. And [...] got it to me FAST!

This works perfectly.... but only has one flaw. The fan is so loud that it sounds like it is taking of for flight. The next size up by the same company sports two fans, yet is quieter. I opened mine up and modded it to include a Panaflo medium speed fan that is much quiter and barely audible now. As a battery backup, it is perfect, you can unplug it and nothing flinches, and it works perfectly. The readouts show perfectly what percentage of the current you are using, and alerts if you overload the battery. Also displays a visable display of how much battery is left when operating solely on battery power. All in all the best bang for the buck...

We have bought a fair amount of these units for network closets in various buildings. They seem to work well and the management cards seem to give us a good handle on the UPS status.
Our favorite feature is that there are basically 3 breakers within the unit you can plug devices into. With the management card you can cycle or turn on/off any one of these breakers remotely, which is fantastic for rebooting gear through the network.
The only complaint so far is that the front panel isn't super clear. When you plug in the UPS and hit the power button several lights come on. You then have to hold the power button for several seconds in order to start providing power to devices. Its not a big issue once you are used to it, but it was less than straightforward for first time users to power the unit up.

I am using this UPS for professional audio equipment so I am not implementing the automated shutdown features it offers for computer systems. The unit is well constructed and was easy to install in an EIA equipment rack. Using the rear rail supports was a bit of a chore as the device was meant for a server rack which normally has a much greater depth than the rack in which this UPS is mounted. A couple of cuts to the adjustable drawer glide style rear support rails with a metal cutting saw and I had attachment points at both the front AND rear of the unit. This UPS has worked without fail for over a year. We tried a few simulated power failure tests when we first bought it (the UPS feature has not been needed in the field yet) and it switched over without loss of power and ran the equipment for a more than ample period of time to allow shut down without incident.

When I purchased a Dell Studio XPS9100 (with some very high horsepower components) for graphics rendering and video production 8 months ago, I didn't know the difference between regular UPS units and Pure Sine Wave UPS units... until repeated power issues at my home/office kept crashing my XPS9100 but didn't seem to bother my Studio XPS8100, which was protected by a traditional CyberPower 1500 UPS. The Tech Support people at CyberPower impressed me by immediately diagnosing the problem and suggesting a solution (Pure Sine Wave UPS). The local wiring issues have still not been completely resolved, so the UPS is triggered several times almost every day... but my XPS9100 AND XPS8100 never know that there's a problem. The controls are idiot-simple and the construction is extremely heavy duty and practical (comes with handles for rack mounting). The battery is easily accessible and you can barely hear the unit when it's running. If you need top quality and dependability in a Pure Sine Wave UPS for a great price, look no farther... because, if you do, you'll end up buying the CyberPower anyway... and I was a loyal APC customer for years.

Apc Smart US1500 Va 120V USB with Alarm Disabled Review

The power in Southern California is not very reliable. I have Sleep Apnea and I have to use a CPAP to sleep properly. Since the power goes out too often I needed some way of using my CPAP when the power is out. We have a generator but that means I have to get up, gas it up, start it up and run an extension cord into the bed room. The generator is also noisy and when the power comes on I have to prepare the generator for storage, a lot of work especially if the power is only out for a short while. I had a really hard time finding a UPS that will always be silent. On some UPS you can silence the alarm using the software for it but they don't stay silent, it seems you have to reset the silent feature from time to time. The alarm on this UPS stays silent. I only hear a "click" and it's not very loud. Also when I'm using a UPS with a computer, I know when the power is out, I really do not need the alarm!

APC Smart-UPS SMT1500 1500VA 120V LCD UPS System Review

APC Smart-UPS SMT1500 1500VA 120V LCD UPS System
Average Reviews:

(More customer reviews)
Purchased this unit a month ago and out of curiosity I connected it through a power meter. The power consumption with no load and batteries at 100% charged is 1.25 Amps. With my IMac plugged in the consumption is at 2.4 Amps. I've owned several APC units before and the no-load current for the trickle charger was about 0.2 Amps. Answers from APC were responsive but unclear as to why this inefficient unit was designed to consume 130 watts with no useful work being done. Also, the fan runs most of the time even though the battery indicator on the display show the charge is at 100% which would seem to make cooling unnecessary. While APC does design some great hardware, in this age of energy efficiency this unit is going in the wrong direction.
