The PS Audio company makes high-performance home audio and video equipment. PS Audio equipment uses specialty cables, including a line of power cords, to provide the best quality possible. There are several imitation power cords available, so it is important to ensure a purchased cable is legitimate. There are a few items to look for to determine if a cord is fake.
Look for the labels on both ends of the power cord. The connection you would plug into the input on the back of your PS receiver will be labeled "PS Audio" in white lettering. On the other end of the power cord that you would connect to the AC outlet, the model type will be printed in white lettering. If you do not see both of these, the cord is most likely fake.
Examine the materials that the power cord is made of. The connections on the AC plug will be made of high-grade copper. The covering of both ends of the cord will be made of rubber, and the cord itself will be made of plastic and sport a black and white snakeskin pattern. This cord also has a gold dotted line running down the length of the cord. If the cord is all black or a different color, or the connections are not made of copper, you may have a fake.
Check the prongs of the AC end of the cord to ensure they are made of a solid piece of copper. The prongs will not have holes on a PS power cord, but will if the cord is a fake. The ground prong located below the two main prongs should also be made of copper and you will be able to unscrew it by turning it counter-clockwise. If you cannot remove the ground prong, you have a fake cable.
