When your equipment loses power, the size and shape of your battery backup matters as much as the battery itself. A rackmount UPS can slide into a server cabinet and handle heavier loads, while a desktop UPS can sit beside a router, modem, or workstation. The APC Smart UPS 1500VA SMX1500RM2U and the CyberPower EC650LCD-R take these two different paths, and with about $195 separating them, choosing the right one comes down to where you need protection and how much power you actually draw.
Quick verdict: If you're shopping for UPS critical power and your equipment lives in a rack, the APC Smart UPS 1500VA SMX1500RM2U is the more capable choice. If your gear sits on a desk and you want a lower-cost battery backup, the CyberPower EC650LCD-R is the sensible pick.

Where the APC Smart UPS wins: It brings a rack-ready design and a maximum power rating that gives it the headroom for enterprise and data-center gear. The APC Smart UPS platform includes USB monitoring, which is practical when you have multiple systems to keep online.
Where the CyberPower wins: It costs far less and still gives you real UPS protection. The ECO outlets can cut power to peripherals when the main computer sleeps, which helps trim standby power use. For a desk or small office, that's a strong feature set at a much lower price.
APC Smart UPS 1500VA SMX1500RM2U USB LCD 2U Rackmount Battery Backup
The APC Smart UPS 1500VA SMX1500RM2U is built for rack environments. Its 2U chassis and 1200W maximum power rating give it the headroom to protect multiple devices that a smaller desktop unit might struggle with. It includes eight outlets, and the APC Smart UPS series is positioned for enterprise and data-center use. With a USB interface and an LCD display, it gives you a clear status readout without needing extra software. Choose it when your gear is already rack-mounted and your loads demand more than a compact UPS can provide. The trade-off is that this particular unit is sold as used and does not include batteries, so plan for the extra step of installing batteries before you trust it with critical systems.
CyberPower EC650LCD-R 650VA/390W 8 Outlets ECO LCD UPS - Certified Refurbished
The CyberPower EC650LCD-R is the compact counterweight to the APC. Rated at 650VA and 390W, it has enough capacity for a desktop computer, monitor, router, and similar peripherals without taking up rack space. The built-in LCD shows voltage, battery capacity, and load level, so you can confirm power conditions at a glance. Its ECO outlets are the standout: three outlets can cut power to USB-connected peripherals when the computer sleeps, which helps trim standby power use. This certified-refurbished unit includes a new battery, and its price is dramatically lower than the APC's. The limitation is capacity; with 390W, it's best matched to lighter desk-side electronics rather than high-power rack gear.
Final choice by use case: Choose the APC Smart UPS 1500VA SMX1500RM2U if you're protecting rack-mounted equipment and need more capacity than a compact UPS can offer. At $249.99, you're paying for the rack-ready design and higher capacity, but the unit does not include batteries. Choose the CyberPower EC650LCD-R if a compact UPS with battery backup and surge protection covers your setup. At $55.19, it's a low-cost way to protect a computer and peripherals, and it comes with a fresh battery.
