Power Supplies: Why do mine keep on failing?

Question: 

Why are my "wall wart" power supplies always failing? 

Answer:

Power supplies typically fail due to the way they are handled. To ensure long life from your power supply, never wrap the cord tightly around the "box". This will cause stain on the cable where it joins the "box" which can cause breaks. This is the most common reason for power supply failure.
