Sudden power loss can cause irreparable damage to home and business computer systems, such as the loss of important data. Save your system and keep on working through power outages with the 120V, APC BE750G Backup UPS. This unit helps to protect your system, with minimal negative impact on the environment. On a daily basis, this 750VA UPS helps you conserve energy courtesy of its Master/Controlled outlets, which prevent peripheral equipment that is not in use from drawing power while your computer is off or powered down. In addition to the computer itself, other related items, such as monitors and external hard drives, are also protected as five of the power supply's outlets provide battery backup. The BE750G also includes software called PowerChute, ensuring that systems shut down safely.
