Many folks who have computers today rely on surge protection strips to protect their computer equipment. Surge protector strips protect your PC from voltage spikes that are associated with lightning or utility problems that can travel along your utility and data lines. Surge protection, however, does not protect you from power outages. Have you ever been at your PC when the lights go out? Too me that abrupt drop in power is just as much a concern (or more so) as voltage spikes.
To take your computer hardware protection to another level and incorporate, not only surge protection, but also provide temporary battery backup during blackouts (and brownouts), I recommend using an Uninterrupted Power Supply (typcially referred to by us in geek world as an UPS). An UPS, during a power outage, will alert you by an alarm that there is a power related issue and will provide you with enough time to safely shut down your PC.
For home usage, I recommend the APC Back-UPS ES 8 Outlet 550VA 120V .
This particular model has (8)-eight outlets, with (4)-four reserved for battery backup; which in most home based setups is sufficient. APC makes numerous other UPS for a variety of needs [click here] .
