Davies beat Aberdovey's Connor Jones 8&7 in the final.
"This is definitely the biggest win of my career," admitted 18-year-old Davies, who won the Irish Boys last year.
"It was different to winning the Irish Boys, though that was my first proper win.
"I feel I have developed my game a lot since then, playing a lot of men's events this year but I have not had the results I wanted.
"It is awesome to get this win, my biggest, though I felt it was coming because I had been playing better and better in recent weeks."
