Surges or spikes are far more dangerous than sags Even a strong sag only shuts off or reboots your PC any surge can harm your computer, and a strong surge destroys components Given the seriousness of surges, every PC should use a surge suppressor device that absorbs the extra voltage from a surge to protect the PC The power supply does a good job of surge suppression and can handle many of the smaller surges that take place fairly often But the power supply takes a lot of damage from this and will eventually fail To protect your power supply, a dedicated surge suppressor works between the power supply and the outlet to protect the system from power surges (see Figure 88) Most people tend to spend a lot of money on their PC and for some reason suddenly get cheap on the surge suppressor Don t do that! Make sure your surge suppressor has the Underwriters Laboratories UL 1449 for 330 V

rating to ensure substantial protection for your system Underwriters Laboratories (wwwulcom) is a US-based, not-for-profit, widely recognized industry testing laboratory whose testing standards are very important to the consumer electronics industry Additionally, check the joules rating before buying a new surge suppressor A joule is a unit of electrical energy Joules are used to describe how much energy a surge suppressor can handle before it fails Most authorities agree that your surge suppressor should rate at a minimum of 800 joules the more joules, the better the protection! My surge suppressor rates out at 1,750 joules While you re protecting your system, don t forget that surges also come from telephone and cable connections If you use a modem, DSL, or cable modem, make sure to get a surge suppressor that includes support for these types of connections Many manufacturers make surge suppressors with telephone line protection (see Figure 89) No surge suppressor works forever Make sure your surge suppressor has a test/reset button so you ll know when the device has as we say in the business turned into an extension cord If your system takes a hit and you have a surge suppressor, call the company! Many companies provide cash guarantees against system failure due to surges, but only if you follow their guidelines If you want really great surge suppression, you need to move up to power conditioning Your power Figure 89 Good surge suppressor lines take in all kinds of strange signals that have no business being in there, such as electromagnetic interference (EMI) and radio frequency interference (RFI) Most of the time, this line noise is so minimal that it s not worth addressing, but occasionally events (such as lightning) generate enough line noise to cause weird things to happen to your PC (keyboard lockups, messed up data) All better surge suppressors add power conditioning to filter out EMI and RFI

No surge suppressor in the world can handle the ultimate surge, the ESD of a lightning strike If your electrical system takes such a hit, you can kiss your PC goodbye if it was plugged in at the time Always unplug electronics during electrical storms!

An uninterruptible power supply (UPS) protects your computer (and, more importantly, your data) in the event of a power sag or power outage Figure 810 shows a typical UPS A UPS essentially contains a big battery that will provide AC power to your computer, regardless of the power coming from the AC outlet

All uninterruptible power supplies are measured in both watts (the true amount of power they supply in the event of a power outage) and in volt-amps (VA) Volt-amps is the amount of power the UPS could supply if the devices took power from the UPS in a perfect way Your UPS provides perfect AC power, moving current smoothly back and forth 60 times a second However, power supplies, monitors, and other devices may not take all the power the UPS has to offer at every point as the AC power moves back and forth, resulting in inefficiencies If your devices took all the power the UPS offered at every point as the power moved back and forth, then VA would equal watts If the UPS makers knew ahead of time exactly what devices you planned to plug into their UPSs, they could tell you the exact watts, but different devices have different efficiencies, forcing the UPS makers to go by what they can offer (VAs), not what your devices will take (watts) The watts value they give is a guess, and it s never as high as the VAs The VA ratings is always higher than the watt rating Since you have no way to calculate the exact efficiency of every device you ll plug into the UPS, go with the wattage rating You add up the total wattage of every component in your PC and buy a UPS with a higher wattage You ll spend a lot of time and mental energy figuring precisely how much wattage your computer, monitor, drives, and so on require to get the proper UPS for your system But you re still not done! Remember, the UPS is a battery with a limited amount of power, so you then need to figure out how long you want the UPS to run when you lose power The quicker and far better method to use for determining the UPS you need is to go to any of the major surge suppressor/UPS makers Web sites and use their handy power calculators My personal favorite is on the American Power Conversion Web site: wwwapccom APC makes great surge suppressors and UPSs, and the company s online calculator will show you the true wattage you need and teach you about whatever new thing is happening in power at the same time Every UPS also has surge suppression and power conditioning, so look for the joule and UL 1449 ratings Also look for replacement battery costs some UPS replacement batteries are very expensive Finally, look for a smart UPS with a USB or serial port connection These handy UPSs come with monitoring and maintenance software (Figure 811) that tells you the status of your system and the amount of battery power available, logs power events, and provides other handy options Table 81 gives you a quick look at the low end and the very high end of UPS products (as of November 2006)
