===Dimensions===
Perhaps the most common method to use in selecting a power supply is comparing the physical dimensions. Make sure your computer case can accommodate the the Height, Width, and Depth of the power supply. If you are replacing an existing power supply then take measurements of it before you discard it. Take a look at the graphic above to gain a better understanding of Height, Width, and Depth. If your power supply is considerably smaller than the typical dimensions of our atx power supplies then it could be possible that you have a micro atx power supplies. If you feel you might have a micro atx power supply then you could compare its dimensions with our 200W micro atx power supply or our 230W micro atx power supply.

===Power Requirements===
You need to know how much power you're going to need. It's okay to buy a power supply that is larger than necessary because the power supply will step down to your power requirements. Power supplies typically deliver only the amount of power demanded from them. On the other hand, buying a power supply that is too small for your requirements will be annoying. Many times people will complain of their computer rebooting for no reason at all. Nine times out of ten the reason for this is an undersized power supply. <ref>Many companies that sell computers will install an undersized power supply to save money and increase profit margins. Buyer beware!</ref>
Below is a sample specification chart that should be printed on the sticker on your power supply. Before you buy a power supply make sure the power specifications are equal to or greater than your need. This way you'll avoid trouble down the road.
