CP1500PFCRM2U PFC Sinewave UPS Battery Backup and Surge Protector, 1500VA/1000W, 8 Outlets, AVR, Short Depth 2U Rackmount; UL Certified

Purchased this CyberPower unit about month ago. Have 2008 MacPro 8 core 3. GHZ fully loaded internally that was running for last couple years along with assorted Monitors-(2), printer etc. Had been using an APC 1500 & APC 1000- splitting various thing around plugged in to either one to share load. A MDD dual processor was in the mix but it was always on the opposite power supply, not both on one APC unit. For the last 3 yrs have been enduring endless stupidity with these APC power supplies. They would shut down randomly & repeatedly EVEN if the MacPro was not the one on that particular power UPS.Although for the most part - the UPS that was on the MacPro would shut down. You could switch a light on in another room- even a 1 bulb 75 watt could essentially trigger one of the 2 APC units to shut down as if they were overloaded. They were not. House is newer & wired correctly with 12 gauge/20 amp romex wire everywhere for any normal 110v outlets & 8 gauge 50 amp for 220v outlets & 200 amp service. The 2 power supplies are on their own line by themselves-nothing else. I am very familiar with house wiring & have rewired several homes I've owned. All wiring in house is up to snuff done properly. I tolerated this nonsense with these APC for years. They made absolutely no sense. I was aware at some point & positively as of recent reading that the 2008 MacPro's had PFC power supplies in them & that they would prefer pure sine wave power- as house current is. Even with that knowledge it still made no senses as to the random-regular weekly shutdown on the APC units with the computer asleep not even trying to wake or even having A TRUE power outage. The batteries checked out ALWAYS and if not hooked up to computer would work fine. If computer was awake & cut power they would hold system for as many minutes long as they were expected to. No problem. Just if asleep- turn light on anywhere in house- units sometimes/randomly cut out. If house current off & wake computers units shut down. Stupid really. Whats the point of the power supply ? (sounds like I am reviewing the APC's not CyberPower-right ?)Finally my MP had 8Gb of ram out of 16GB go bad. Had it replaced and I said that's it. I mean really- the APC power supplies were shutting down on a almost weekly basis & there wasn't even any power failures- the units themselves were THE power failures. Did as much research as possible regarding PFC power supplies & chose the CyberPower PFC 1500 unit. Cost more than the similar NON pure sine wave APC units. But cost quite a bit less than the Pure sine wave APC units. Who knows why APC charges so much for pure sine wave units. But after using their product probably for nearly 15 yrs- I was done. The CyberPower unit is a GREAT unit. Have read various reviews about the power switch(on unit-on/off & menu) etc problem some are having with it-I don't get the problem. It is a bit of a different technique how the button operates- but I picked it up quickly. The current power draw in numbers of watts as well as load capacity being used on the LCD display is great. You have real-time readout if you chose to, as to those numbers. It's like having Kill-A-Watt meter always on. You get to see the basic power fluctuations of your components. The unit is very compact- somewhat smaller than the APC 1500/1000 units. Right now connected with MacPro w/4 Hitachi 7200 rpm 64MB cache 3TB drives internal, ATI/Apple 5870 video card- w/3 24" monitors, epson 3800 printer, external OWC QX2 raid case w-4 hitachi 7200 rpm 32 MB cache 2TB drives & 2008 8 core MacPro booted off of that raid case along with MBP early 2011-17" plugged in but asleep, DSL modem, Dlink 8 port gigabit ethernet hub, 5th Gen AirPort extreme, MDD G/4 plugged in but off, the CyberPower shows a load of about 564 watts. That draw is confirmed accurate(slightly less actually for CyberPower unit itself not being in mix) if all were disconnected from CyberPower unit and plugged in- instead to the Kill-A=Watt meter. Everything asleep around 54 watts draw. I can switch ANY combination of light/appliance/central a/c /55" plasma/electric 220v clothes dryer/3.5HP 220v air compressor/ 5500watt electric heater- 500 gallon spa w/dual pumps etc in any combination on or off with computers asleep, awake, getting awake, going to sleep. UPS functions PERFECTLY & as expected- stellar performance. NO random shutdowns-nothing. Cut power to unit while computers asleep-no problem. You know the conclusion here -right? Pro's * Economical, compact, nice looking * PFC compatible- Pure Sine Wave unit. * Operates flawlessly * Cheaper than APC pure sine wave units * Power consumption/load LCD is very useful if you like that sort of thing-I do * 3yr warranty -same as APC Cons * Cost more than NON PFC compatible/Pure Sine Wave units * CyberPower warranty/service- unknown quality yet. APC was/had excellent service Conclusion. Highly recommended, especially if you have any of the MacPro's. I imagine some on PC side have units that are PFC and would require pure sine wave to operate a UPS on those computers properly also. I will not ever buy a UPS that is not a pure sine wave unit again.

CyberPower CP1500PFCLCD PFC Sinewave So good, I bought 2! UPS systems in this class can easily cost more. I have had poor experience with APC systems in this range, so I gave CyberPower a shot. First one I bought for all my network equipment. I bought the optional network card as well. I have a couple routers attached, several WiFi Mesh base units attached by PoE router, laptop, NAS and a couple other items. I get 1 hour or more of uptime! (YMMV, yada yada) All the items I have attached amount to about 40% load if they are all on at the time. The 2nd UPS I bought about a year later for my home entertainment stuff - TV, stereo and a couple miscellaneous network items. Also gets about 1 hour uptime. No net card on the 2nd one, I wanted to test connecting it to HomeIt via HomeBridge and RPi. I don't need to manage these UPSs on a regular basis. We live in the mountains and power can be flaky. I wanted to have some way to monitor utility power when I was at work. The NIC adapter is perfect for that. I think it is a little on the $$ side, but has been worth it. Plugs right in and easy to configure. I started out with a 1 year promotional subscription to their service, but don't really need it. I still get power change notifications even without the subscription. When I get a power out notification I know I have about 1 hour of uptime before I need to turn on the generator. I did get the other CyberPower UPS to hook up pretty easily to my RPi unit running HomeBridge, with NUT UPS plugin. NUT can have a reasonably steep learning curve. I did get it working, but haven't really had the need to play with it too much since I still have the other UPS with the NIC. FWIW, I already had the RPi unit in place for a bunch of other IoT integrations with HomeKit - I would not go that route just for UPS management! ;P A word about generators: Most UPS systems will not play nicely with your standard portable open frame generator, regardless of how large/stable it is. It's the shape of the stepped wave that can often fool the UPS causing it to trip on. The only foolproof way around that is to 1) Get an online UPS system at 3-5 times the cost of line-interactive 2) get an inverter generator. Don't get too fooled by 'generator' modes on line-interactive or standby UPS types. Those modes may help, but in my experience it will not work 100% of the time. Initially I had a standard Champion 7kw open frame delivering power to whole house. Performance was rock solid voltage and frequency delivery without fluctuation. These CyberPower systems worked off the generator about 75% of the time, tripping on the rest of the time. I have a couple APC systems with 'generator' mode that would have nothing to do with the generator - they would trip instantly even in 'generator' mode. Still, this was not stable enough for me. My solution was to get the inverter generator - a 9kw Westinghouse delivering power to the whole house. It was actually cheaper than getting an online UPS equivalent to this CyberPower! Ultimately it wasn't just the lower cost, but the versatility and stability of delivering super clean pure sine to the whole house. Better for everything inside. Zero issues, of course, with these CyberPwoer UPSs. They just see the generator output as regular utility power.

Great and practical, powerful enough. Put on it my home NAS server, two machines, two routers, works fine. Quiet. Produced hint of chemical smell right from the start after first use, then in a week it was gone.

This unit is a lifesaver. I currently have two of these (1500VA) and they have paid for themselves already. Due to some recent brown outs in my area, I was forced to buy a second one, because I needed to protect a few more machines outside of my office. Just yesterday we had 4x within minutes and I happened to be working on a machine not protected...that was not fun. I ordered another unit for same day. Easy installation and works right out of the box, as opposed to some other ones I have had that require charging prior to adding devices. Battery life is good for my gear. The display calculates ~58 minutes of battery if a black out occurs. Plenty time for me gracefully shut down my gear...IF I am home. I would also suggest using some power cord extention adapters, as there are no universal power cord rules and some device plugs can take up 2 or more ports, just because of how they plug in. I have found that the extenders are great and resolve that issue. https://www.amazon.com/dp/B07H9MCTGL?ref=ppx_pop_mob_ap_share

I'd been in need of a whole new UPS, as my smaller 350W ones from 2008 were now no longer charging batteries and would drop the second any type of power issue was detected so grabbing this as its then price of $400 for a 1500VA 1000W UPS was far too good to pass over. I have a 1500VA, 1500W CyberPower UPS for my homelab's rack, so I'm already a heavy fan of CyberPower. Pro's: The unit isn't too heavy and it's shallow depth makes it ideal for limited space in a rackmount, and it doesn't bend the rack up. Ironically, my managed switch puts more of a wow in the rack posts than this unit does. o.O User interface is generic, simple and easy-to-use. If you've used any UPS before then there's really no need to worry about display settings and how-to's. It's got the new built-in green energy system that when the UPS is charged and not on battery, it auto-bypasses the transformer and reduces energy consumption and waste by 75%. Unit switches over from utility to battery quickly, quietly and returns to normal just the same. NO LOUD FANS! In fact, I didn't even notice let alone hear if there was even fans in this unit which is very nice! So bonus on it being ultra quiet! Came to me with 92% full charge, so not a lot of time needed to fully charge it before putting it into production. And last but most important of all: She has that beautiful and wonderful strong fresh/new electronics smell one can't help but admire and relish. That alone was worth the $400 ;) Cons: Unit says default setting is MUTE when running on battery. They lie! ;) Easy fix, though! The screws for the rackmount holes were too small for the back bolts on my rack, and I had to use the screws that came with my rack. You may have different results depending on your rack.

We have these at work in crappy conditions with even more crappy power and they are abused.... never failed. I bought one for myself. If you can't afford some monstrosity from APC these are you next best bet for like half the price.

Lots of outlets, informative front panel, competitive price, generally a nice looking device -- there's a lot this UPS does very nicely. But I need to underline one problem mentioned by a few other reviewers: the 1500VA model emits a high pitch tone around 2kHz -- almost certainly coil whine. It's not extraordinarily loud, but it's audible within the vicinity of the room, and inside the room I find it intolerable. It even occurs when the UPS is powered off, but vanishes once the UPS is unplugged from mains. I might chalk it up to a specific defect of my unit were or not for other reviewers commenting about the same issue with the 1500VA, one even getting a replacement which behaved the same way. If you're not sensitive to such high pitches, or you plan to keep the UPS in a dedicated room with other noisy gear, then I can recommend it. But if noise is a concern, unfortunately my advice is to look elsewhere than the CyberPower CP1500PFCRM2U.

Je suis satisfaite des résultats de ce produit car nous sommes sur un point sensible d’'hydro avec nos très nombreux arbres ce qui fait que lorsque nous avons des grands vents, les branches casse sur les fil d’hydro et le courant joue ce qui est très dur sur les pièces électronique.

I have owned this 2 weeks and just installed it. This unit is very nice to look at. My first impression was good but there is one main issue. The high pitched coil whine (see video). While if in a server room would be fine, it's in a quiet den. It's like a dog whistle. Barely there, but once you hear it, it irritates you. Oddly, only perceptible while the LCD screen is off. If you wake up the display, the whine is so low you can't really hear it. Too bad you cant keep the display on. Unit powered on or off, that whine is there as long as it is plugged in. It has ruined the appeal of this device. None of my 4 APCs in the house make this whine. If you want peace and quiet, buy APC or avoid this rack model type.
