Choosing a UPS for critical power protection usually comes down to budget, space, and what you need to keep running. You're looking at two used APC units: a $64.99 Back-Ups PRO 1000 BR1000G and a $249.99 Smart UPS SMX1500RM2U. Both are APC UPSs, but they're built for different realities-one is a simple desktop companion, the other a rackmount workhorse. Here's how to decide between them.
Quick Verdict
The Back-Ups PRO 1000 is the clear pick for a single workstation or small office on a tight budget. The Smart UPS SMX1500RM2U is the better fit if you need a rackmount unit for higher-demand equipment-just remember that batteries are not included.

Where Each Product Stands Out
For the Back-Ups PRO 1000
If your gear sits on a desk or under a table and you want working power protection without the rack footprint, this unit keeps things simple. It includes a battery carrier, so you can add a battery that matches your needs, and it's a straightforward way to get APC backup without the rackmount commitment. Just be aware it's a used unit and doesn't offer the same high-power rating as the rackmount model.
For the Smart UPS SMX1500RM2U
This is the one to choose when your equipment lives in a server rack and needs more headroom. The 1500VA/1200W rating and USB LCD give you a clear look at power status, and the 2U form factor slides into standard racks. The catch is that batteries are not included, so you'll need to factor that into the total cost.
Product Notes
APC Back-Ups PRO 1000 BR1000G 8 Outlets UPS w/Battery Carrier
This used APC unit gives you eight outlets and a battery carrier, making it a practical foundation for a desktop backup system. The carrier lets you choose a battery that fits your needs, but you'll have to supply the battery itself. It's a compact design that won't take over a shelf, and it's a good match for lighter electronics like a computer, monitor, and network gear. The trade-off is that it lacks the wattage rating and rackmount frame of the Smart-UPS, so it's not aimed at a full server rack.
APC Smart UPS 1500VA SMX1500RM2U USB LCD 2U Rackmount Battery Backup
This rackmount UPS is built for a server room or network closet. The 2U form factor fits standard racks, and the USB LCD gives you a clear readout of power conditions. It's rated for 1500VA and 1200W, which gives you more headroom than the Back-Ups PRO. The catch is clear in the description: it does not include batteries. You'll need to add batteries before it can protect anything, so plan your budget accordingly. Its used condition also means you should inspect the unit for wear before relying on it for critical gear.
Final Choice by Use Case
Choose the Back-Ups PRO 1000 if you need simple backup for a single computer or small office setup and you're comfortable adding your own battery. Choose the Smart UPS SMX1500RM2U if you have a rack and need more power for serious equipment-and you're ready to buy batteries separately.
