I think it's different from the standard IEC power connector, so you can't just snag a PC power cord. You could get Outlaw\'s recommendation , assuming nobody else around the forum today have gone through the same process before.
You could order a 20 amp IEC female plug online and then buy a suitable length of 12/3 power cable from your local Home Depot and put a high quality plug on the end.
and order a custom cable. I think the connector you want on the equipment end is a IEC-60320-C19. But perhaps someone else on the list can confirm that.
