Hello Sugith - I think you have things backwards. The PS Audio Punch power cords that I have seen all have the unpolarized ends - two round connectors, so I have to assume that the Apple TV has a polarized C7 input ( one round and one with a flat spot). AppleTV's website is awful in that it gives no closeup of the back panel nor is there mention of the type of power cord required anywhere I can find, so I am guessing on the Apple TV, while I know for a fact on the PS Audio cord. There might be an adapter somewhere, but I do not know of one - sorry. Filing the flat spot on a standard C7 to make it fit the polarized input is NOT a good idea. Companies use a polarized input plug for a reason....
Upgrading Apple TV power cable
I bought a PS Audio Power Punch PC C7 cable to replace the stock Apple cable that came with my Apple TV, (which is plugged into an external DAC as a music server).
But the PS Audio power cable has a POLARIZED C7 end and the Apple TV is an UNPOLARIZED receptacle. Are there high grade adapters available? I didn't see anything that would have let me buy an unpolarized version of the power cable.
