Monster Multiple Surge Guard Circuitry... absorbs harmful power surges to give you... Computer System Surge Protection. Lightning, automatic garage doors, power tools, refrigerators and fluorescent lights all cause power surges and voltage spikes that can travel up AC power lines and coax cables to damage your computer system. Even a momentary power surge can destroy valuable data stored on your hard drive. Worse yet, costly damage can occur to the sensitive electronic circuitry of your motherboard. Ordinary surge protectors, or the so-called "value brands", often fail to provide the adequate level of safeguards you need to protect your valuable data and equipment. A properly designed surge protector can help protect your sensitive computer components. Proper connection to an advanced surge protector with integrated system protection, via Internet/Phone line protection as well, the PC800 can help minimize the risk of surge damage to your system. Unlike standard surge protectors, the Computer PowerProtect PC800 with SurgeGuard protection provides multiple layers of defense against harmful surges. Strategically placed multiple Metal Oxide Varasitors respond within one nanosecond (a billionth of a second) to power surges and voltage spikes before they can reach and damage electronic circuitry. Monster PowerCenters make life easier. Monster's FlatProfile plug lets you push your furniture flush against the wall. And, with eight color-coded outlets and cord labels, you can avoid unplugging your computer by mistake - possibly causing valuable data loss or damage to your hard drive. Finally, a generous eight-foot Monster power cord, which is the optimum length to reach most electrical outlets, is included.
