BTW, I would recommend you avoid making your power cable too precise.  There will always be times when you want to move things around, so the shortest I'd recommend is 3'

Thanks for the information, Erik. I’m looking for an off the shelf solution.

I live in a small apartment, the rack is not going to move, it will stay 20 inches from the wall which had two dedicated 20A circuits, and the Niagara 5000 will be put standing up on its side against the rack. So, I don’t need a long power cord.

Check THE CABLE CO. you may be able to demo a couple of power cords.

I don't know what "reasonably priced" means.  But here are a couple options I see:

And Audio Sensibility makes several cables that have an option for 20A IEC.  They are in Canada and pricing is CAD.  USD is about 75% of CAD right now.  The minimum IEC they offer is the Statement SE, which is 384 CAD or $283 USD.  The Statement model is likely better because it's larger at 11awg, but much more expensive.

Power cords with 20A IEC can be hard to find because many companies only offer this as an option.  Not sure if "The Cable Company" would have many or any to test because this is not really the norm.
