Caersws won their penultimate game of the season despite going behind just before the hour mark at The Oval.
Mark Evans picked up a long ball played out of defence before shooting past Andy Mulliner.
Caersws responded in magnificent fashion as Andy Marfell hooked the ball past David Walsh in the Town goal.
Andy Davies then came close to doubling the lead before Ricky Evans created another chance which Davies sent Caersws into the lead from 15 yards.
As Caersws continued to push forward Geraint Lewis struck the woodwork with Walsh making tipping over the rebound from Hugh Clarke.
Caersws' scored soon after as a 40-yard break from Graham Jones set up Graham Evans who sealed the win five minutes from time.
