Power adapter/cord for the Power Mac G5 A1177 EMC 2023?

How do I determine the correct power adapter/cord for the Power Mac G5 A1177 EMC 2023? I suppose I would need a part number or identifier to look for a replacement.

So far, I haven't been able to determine the answer from Apple's support search or other search methods. I do not have an original user's manual but the one I found on the net doesn't specify the correct power cord.
