When we used Raspberry Pi's last year we bought a second power supply that is used for the wireless router. It gives a solid 5v under extreme conditions, hence the reason it is required for the radio. Of course you would need to power it off of the PD through a 20A breaker since it is a custom circuit. It worked great for us, but did raise some questions since there were 2 and 1 of them was plugged in to a 20A breaker. Just know the rules and be able to explain why you did it the way you did it and the inspectors will pass it.
