Choosing between two rackmount UPS units without batteries is really a question of matching capacity to your rack and your tolerance for defects. On one side, the CyberPower OR500LCDRM1Ua is a smaller unit priced at $82.50. On the other, the APC SRT3000RMXLA is a rackmount UPS listed at $203.62 with a much higher capacity. Both are used, both list universal compatibility, and neither includes batteries. That means the sticker price is only the starting point; you will also need batteries and possibly small accessories such as rack brackets.
Quick Verdict
If your load is light and your rack space is tight, the CyberPower OR500LCDRM1Ua is the practical choice. If you need serious capacity for heavier equipment, the APC SRT3000RMXLA is the one that can handle it. Keep the condition notes in mind, especially for the APC.

Product Notes
CyberPower OR500LCDRM1Ua
The CyberPower is the space-saving route for a smaller rack setup. The 1U design leaves room for other gear, and the feature list includes automatic voltage regulation, an LED display, an audible alarm, remote monitoring, surge protection, and a modular rack-mountable layout. For a network closet with a modest load, this unit keeps things simple. The trade-offs are straightforward: rack mounting brackets are not included, and the power button cover does not fully close. If you are comfortable sourcing those extras and working with a minor cosmetic issue, the CyberPower is a solid pick for a smaller rack.
APC SRT3000RMXLA
The APC is the higher-capacity option in this pairing. Its 3000VA / 2700W rating is the main reason to choose it, and the 2U rackmount form factor is sized for more substantial critical-power loads. That makes it a better fit for equipment that draws more than a small UPS can support. The caveats are significant: front bezel retaining clips are damaged, the rear USB port is defective, and the overall Grade C condition may include cosmetic wear and missing or defective functional components. It was removed from a working environment at the end of a lease. The damaged USB port deserves particular attention if you plan to rely on USB connectivity in your setup. If you need the wattage and can work around those issues, the APC is the one to build around.
Final Choice by Use Case
- Compact rack, light load, tighter budget: CyberPower OR500LCDRM1Ua
- High-wattage rack, heavier equipment, defect-tolerant: APC SRT3000RMXLA
Both make sense in different environments, but only one will fit your specific power load and your tolerance for cosmetic defects.
