Kick-Starting Your Computer 20 Connecting the Power Cables Once you've connected all the accessories to your system unit, you can plug the system unit and accessories into a power outlet. Because you probably don't have enough outlets to plug in all your equipment, purchase a power strip, surge suppressor, or uninterruptible power supply (UPS). These devices have several outlets for plugging in additional equipment. Plug the power strip, surge suppressor, or UPS into the outlet, and then plug your system unit and all external accessories into the power strip, surge suppressor, or UPS. If the power strip, surge suppressor, or UPS has a power switch, make sure it is turned on. Inside Tip A simple power strip offers no protection against power surges and lightning bolts. Get a surge suppressor with a UL rating of 400 or less; the UL rating represents the maximum voltage that the surge suppressor will let pass through it. Make sure it has an energy absorption rating (which represents the amount of energy the suppressor can absorb before it's toasted) of 400 or more. A UPS has a built-in battery that supplies power to your computer for a short period of time during blackouts, giving you time to close documents and shut down your computer properly.
