CyberPower CP1500PFCRM2U PFC Sinewave UPS System, 1500VA/1000W, 8 Outlets, AVR, Short Depth 2U Rackmount

I needed a rackmount UPS for my home lab. This one is a great value for a 1500VA UPS in such a small form factor, and it runs my server for nearly an hour without power, fantastic!

Great UPS unit. I was powering 3 R710s and a DL380 GEN 9 with this. It had no problem and would give them just enough time to shutdown in the event of a power outage.

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.

I deal with Enterprise Data Centers, but for my home lab I wanted something more affordable so so thought I'd try Cyberpower. I'm glad I did. This unit effortlessly provides full power as advertised, as well or better than other UPS I've used. Highly recommended.

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.
