The effects of power problems include keyboard lockup, complete data loss, hardware degradation, damaged motherboards, and more, making downtime inevitable. An APC Back-UPS CS instantly switches your computer to emergency battery backup power and allows you to work through brief power outages or shut down your system during an extended outage. High-performance surge suppression protects your computer from electrical noise and damaging power surges - even lightning.

The Back-UPS CS has both serial and USB capabilities. The product includes USB software and the necessary cable in the box for free. The serial software kit is also available via a mail-in coupon.
