Choosing between the CyberPower OR500LCDRM1Ua and the CyberPower CP1500AVRLCD3-R is really a trade-off between a lower-priced rack project and a complete, ready-to-run tower. The OR500LCDRM1Ua is a used 1U UPS chassis listed at $82.50, and it arrives with no batteries. The CP1500AVRLCD3-R is a certified refurbished mini tower listed at $147.19. If you need critical power protection now, one of these is far easier to put to work.
Quick verdict: If you want a backup unit that can protect a desktop computer, workstation, or network setup without additional parts, the CP1500AVRLCD3-R is the more sensible pick. It offers more output capacity and a clearer status panel. The OR500LCDRM1Ua makes sense only if you already have compatible batteries and want a rack-mount unit at a lower price.
| CyberPower OR500LCDRM1Ua | CyberPower CP1500AVRLCD3-R | |
|---|---|---|
| Listed price | $82.50 | $147.19 |
| Condition | Used | Certified Refurbished |
| Form factor | 1U rack-mountable | Mini tower |
| Battery situation | No batteries included | Recharge time listed as 8 hours |
| Output capacity | - | 1500VA / 900W |
| Outlets | - | 12 NEMA 5-15R |
| Display | LED | LCD |
| Notable features | AVR, surge protection, audible alarm, remote monitoring | AVR, surge-only outlets, USB-C/USB-A/USB-B/RJ45/serial |
Where the OR500LCDRM1Ua wins: It is the lower-priced entry point and fits into a rack environment. The chassis is built around rack-mounted installation and keeps the option open for a self-managed setup. Where the CP1500AVRLCD3-R wins: It is the more complete unit. The tower form works on a desktop or shelf, and the larger capacity leaves more room for connected devices. The certified refurbished condition and the extra connection options make it a more polished package.
CyberPower OR500LCDRM1Ua 1U UPS System NO BATTERIES

The OR500LCDRM1Ua is a rack-focused unit for someone who already has the battery side covered. Its rack-friendly form factor, LED display, AVR, audible alarm, and remote monitoring are useful in a server closet or equipment rack, and the modular design keeps it flexible. What holds it back is the missing pieces: the rack mounting brackets are not included, the power button cover does not fully close, and batteries must be sourced before it can run. That makes this a project UPS rather than a drop-in replacement. If you are comfortable supplying those extras, the lower upfront cost is a reasonable trade.
CyberPower CP1500AVRLCD3-R 1500VA/900W Mini Tower UPS - Certified Refurbished

The CP1500AVRLCD3-R is the easier recommendation for most desktop and network setups. It provides 1500VA/900W output, 12 NEMA 5-15R outlets, and an LCD panel that shows battery and power conditions. It also includes USB-C, USB-A, USB-B, RJ45, and serial connections, with an eight-hour recharge time listed. The tower layout means you can place it on a desktop or shelf instead of planning around rack rails. The main limitation is that it costs more than the rack unit, and if you specifically need rack-mount hardware, this is not shaped for that. For a ready-to-run UPS, it is the more complete package.
Final choice by use case If you need a finished UPS for a desktop PC, workstation, or small network stack, choose the CP1500AVRLCD3-R. It has the capacity, outlet count, and status display to handle a typical setup right away. If you are outfitting a rack and already own compatible batteries, the OR500LCDRM1Ua is the more targeted pick. Just remember that you will need to supply batteries and mounting brackets before it can protect anything.
