Rackmount or Tower? APC Smart UPS SMX1500RM2U vs Back-UPS Pro BR1500G

Need a UPS but can't decide between the 1200W rackmount Smart UPS SMX1500RM2U and the 865W tower Back-UPS Pro BR1500G? We compare power, outlets, condition, and price to help you choose.

Last updated Aug 17, 2026

When you're protecting critical gear in a ups critical power setup, the real decision is often about where the unit will live and how much power you truly need. Do you have a 2U space in a rack, or are you looking for a self-contained tower that sits near your desk? We're comparing two APC options that answer that question very differently.

Quick verdict

If you need the most power per outlet and have rack space, the APC Smart UPS 1500VA SMX1500RM2U delivers 1200W from 8 outlets in a compact 2U rackmount body. If you'd rather keep things simple with a new, freestanding tower that offers 10 outlets and automatic voltage regulation, the APC BR1500G Back-UPS Pro is the lower-cost, easier-to-place pick.

Where each wins

The Smart UPS SMX1500RM2U wins anytime your gear lives in a rack. Its 2U design matches standard network equipment, and the 1200W rating gives you headroom for switches, routers, and small servers. It's also the higher-output unit of the two, so if your load is close to or above 865W, it's the only one that can keep up.

The Back-UPS Pro BR1500G wins for price and everyday practicality. At $191.95 versus $249.99, the $58.04 price difference is meaningful when you're outfitting a home office. It comes in new condition, packs 10 outlets-two more than the rackmount-and its tower footprint sits neatly on a desk or floor. It also includes surge protection and Automatic Voltage Regulation (AVR), which are useful for smoothing out minor power fluctuations.

Product notes

APC Smart UPS 1500VA SMX1500RM2U

APC Smart UPS 1500VA SMX1500RM2U USB LCD 2U Rackmount Battery Backup

The SMX1500RM2U is built for environments where space is premium: a 2U rackmount chassis that slots into standard racks and provides up to 1200W of power across 8 outlets. The USB port and LCD display make it easy to monitor status, and the black design blends with most data-center gear. Choose it when you need the higher wattage and a rack-friendly footprint. The catch: this unit is listed as used, and notably, it ships without batteries. That means you'll need to source replacement batteries before it can actually protect anything, which adds cost and effort you should plan for.

APC BR1500G Back-UPS Pro

APC BR1500G Back-UPS Pro, 1500VA/865W, Tower, 120V, 10x NEMA 5-15R outlets

If your power-hungry devices are clustered around a desk, the BR1500G offers a lower-priced, new alternative. It provides 865W of power through 10 NEMA 5-15R outlets, giving you extra connections for peripherals. The tower shape keeps it out of the way, and the built-in Automatic Voltage Regulation (AVR) helps smooth out minor fluctuations without switching to battery. Choose it when you want a ready-to-run unit that includes surge protection and AVR at a lower price. Just note that its 865W capacity is less than the rackmount's 1200W, so it's not the pick for a serious server stack.

Final choice by use case

For a rack-mounted network setup: choose the APC Smart UPS 1500VA SMX1500RM2U and plan for the battery purchase. For a home office or small desk setup: choose the APC BR1500G Back-UPS Pro for its new condition, extra outlets, and lower entry price.
