Choosing the right backup power for a compact network stack usually means deciding between a tower unit that eats up shelf space and a rack-mount unit that fits neatly in a cabinet. The CyberPower OR500LCDRM1Ua is aimed at the second group, but this particular listing is a used unit that arrives without the parts that make a UPS ready to use. The listed price is USD 82.50, which makes it an appealing figure on paper, but you have to factor in extra work before it can do anything.
Quick verdict
If your project calls for a 1U UPS with automatic voltage regulation and a compact rack-mount footprint, the CyberPower OR500LCDRM1Ua is worth a close look. Just understand that this unit needs extra components and has a small cosmetic flaw. That makes it a better fit for someone who can complete the setup than for someone looking for a ready-to-go install.
Who it suits
Buyers who already manage a rack and are comfortable finishing a UPS can get a lot from this unit. It also suits anyone who wants a used 1U UPS to repurpose in a home lab or small equipment room, provided they are okay with a slight cosmetic imperfection.
What stands out from the listed details
This is a 1U form-factor UPS from CyberPower with attributes that point toward network-cabinet use: an LED display, audible alarm, surge protection, automatic voltage regulation (AVR), remote monitoring, and modular construction. The maximum input current is listed at 15 A, which is worth checking against your circuit before installation. The unit is described as being in excellent cosmetic condition and comes in black.
Meaningful trade-offs
The biggest trade-off is that the title states No Batteries, so this is not a plug-and-play UPS. You also need to supply rack mounting brackets, since they are not included. On top of that, the power button cover does not fully close. If you are okay with those gaps, the listed price of USD 82.50 may look reasonable; if not, factor in the cost and hassle of the missing components.
Bottom line
The CyberPower OR500LCDRM1Ua is a capable-looking 1U rack-mount UPS for someone who wants to complete it themselves. It offers surge protection, remote monitoring, an LED display, and a compact 1U profile. It is not a one-and-done purchase because the unit needs components you'll have to source. At USD 82.50, it is best seen as a project UPS for a buyer who already knows what they need to add.
Product note
CyberPower OR500LCDRM1Ua 1U UPS System NO BATTERIES
If you need a rack-mount UPS with a 15 A input in a 1U slot, this model gives you the foundation to build on. The catch is that it is a used unit that expects you to fill in the gaps, and you will likely notice the button cover not closing fully. For the right rack owner, this is an appealing starting point rather than a finished solution.
