Alan Pardew's side are sure to provide a formidable barrier to progress in the competition but Powell remains keen to show he can handle playing against Barclays Premier League opposition.
"It will definitely be a good test for us," he insisted to the United Review. "Newcastle did really well last year and were pushing for a top-four place. They're a good side. It'll be a great experience for whoever is playing this evening and a tough challenge. If I'm involved, I hope it's one I can rise to. If I get my chance, I'm determined to take it with both hands."
