Summary: Watch out for the BX versions that are frequently sold in brick-and-mortar stores. Though they look like their BR counterparts, there are differences. Check APC's knowledgebase for details.

Finally, on a system equipped with a 17\" LCD monitor, QX6700 CPU, 680i motherboard, 2x SATA drives, and a 8800GTX with 850W power supply, the system draws 280W idle, and 360W in intensive games. Even with a 1500VA UPS, this means that average runtimes will be 17 min (idle) and ~7 min (gaming).

Summary: Be sure you purchase the \"R\" version and not the \"S\" one. The R isn't that much more and has a lot more capabilities. We get a lot of both under and over voltages here and this unit does a great job of trimming them and not going over to (and wasting) the battery.

Summary: This is the second APC Back-UPS RS 1500VA I've purchased and I'm very happy with both. This UPS does it's job and will protect your computer equipment against a blackouts and surges. I'd recommend this APC Back-UPS to anyone looking for a home or small business UPS system. We experience blackouts quite frequently and this battery has kept our computer running like it's suppose to. The software that comes with the UPS is easy to install and allows you to check your APC unit. APC is the only brand I trust for surge and UPS equipment and I've purchased several of their products over the years and always been happy I did. APC also has great customer support which is hard to find now-a-days.
