Installing a Power Supply - An Easy-to-follow 11-Step, Photo Illustrated Guide

Warning: Power supplies contain capacitors that retain power even when the power supply has been powered down. Before you begin your installation make sure you ground yourself to prevent injury. If you don't have a grounding antistatic wrist strap, you can ground yourself by touching any of various household objects, such as a water pipe, a lamp, or another grounded electrical device. And be sure to unplug the power cord before you begin to work.

When you've upgraded your PC system by adding on a number of new peripherals it might be time to upgrade your power supply as well. Please note that many popular PC systems use power supplies made especially for those systems and cannot be replaced. Read your instruction manuals to make sure your PC's power supply can be upgraded. Otherwise, you will need to purchase a new computer case that will accommodate a larger power supply than the one you are presently using. However, if you are able to upgrade your power supply, the following 11-step guide with accompanying photographs will help you complete installation in 5 to 10 minutes using only a Philips screwdriver.

Note: Be sure to consult your user manuals when embarking upon any PC installation project. Computer systems and components vary and manufacturers may make slightly different installation recommendations

The shape and physical layout of a power supply is called its "form factor". Power supplies come in several industry standard form factors. Power supplies with the same form factor are physically interchangeable. Although two power supplies may have the same form factor, they can differ in quality, power rating, features, and efficiency. Make sure to purchase a power supply that not only has the proper form factor to fit into your computers case, but also has the required power rating to drive your motherboard and other system components.
