When you're sorting out UPS critical power, the decision comes down to how much load you need to cover and where the unit will live. Two used APC options represent very different angles on that problem: the APC Smart-UPS SMX1500RM2U and the APC Back-Ups Pro BR1000G. Both provide eight outlets, but they make very different trade-offs.
Quick verdict
The right pick depends on your environment and load. Choose the Smart-UPS if you need more headroom for heavier equipment. Choose the Back-Ups Pro if you're putting together a simpler setup.

Where the Smart-UPS wins
The Smart-UPS SMX1500RM2U is the one for installations that demand more than basic backup. Its higher VA and wattage ratings give it a clear edge, and the 2U rackmount form factor fits cleanly into server cabinets. That makes it the more capable unit in this head-to-head.
Where the Back-Ups Pro wins
The Back-Ups Pro BR1000G is the pick when cost matters most. The $185 price gap is substantial, so you can add battery backup without the higher layout. If you just need a simple backup solution, this is the easier way to protect a few devices.
Product notes
APC Smart-UPS SMX1500RM2U
This Smart-UPS includes a USB LCD for at-a-glance status, which is helpful when you're managing critical power. The batteries are not included, so you'll need to budget for replacements before the unit can do its job. It's a capable foundation, but the total cost goes beyond the ticket price. Add the replacement cells and you have the makings of a serious critical power setup. If you already have spare batteries or a preferred source, this shortfall is manageable. For a professional environment, the lack of bundled batteries is an extra step, not a deal-breaker. Plan for that cost and the Smart-UPS becomes a strong fit. That's a trade-off worth planning around, especially if this is your primary backup.
APC Back-Ups Pro BR1000G
The Back-Ups Pro BR1000G is a used UPS with a battery carrier, giving you a functional starting point for protecting equipment. Its 1000-series model number places it below the Smart-UPS in the lineup, so treat it as a solution for lighter loads. Since it's used, the condition of the battery carrier and unit need close attention. If you're putting together a basic backup setup, this is the one. Just be realistic about what a 1000-series unit can handle. The battery carrier is a useful inclusion, but it only matters if the unit is in good working order. If your goal is to keep a few devices running during short outages, this unit covers that ground.
Final choice
If your equipment needs higher-rated power and a more robust UPS, the APC Smart-UPS SMX1500RM2U is the long-term choice. If you're protecting a simpler setup and want a quick way to get battery backup, the APC Back-Ups Pro BR1000G is the practical buy. Let your environment and load demands be the deciding factors.
