What We Like
- Pure sine wave — safe for any modern PSU
- USB-C + USB-A charging ports
- 1500VA/900W, 10 outlets
- Energy Star, efficient at idle
- Cloud management via APC app
Worth Knowing
- ~$300 — pricier than BX1500M
- Pure sine only matters for some PSUs
- Still heavy and bulky
- Overkill if you only protect a router
Who Is This For?
Owners of gaming PCs with active PFC, NAS servers, home theater amps and medical/audio gear that demand clean sine wave power.
The Full Picture
Modern enthusiast PSUs with active PFC can misbehave on stepped/square wave output — shutdowns, coil whine, even damage. The BR1500MS2 outputs a true pure sine wave, so it is the right choice for a $2,000 gaming rig or a NAS with spinning drives. It adds USB-C device charging and cloud monitoring, and at 1500VA/900W it carries the same load as the BX1500M. If your gear is high-end, spend the extra ~$110.
Bottom Line
The pure sine wave 1500VA UPS for sensitive electronics — APC BR1500MS2.
