Gowda, who turns 30 tomorrow, threw the iron disc to a creditable 64.90m in his fourth attempt to win his first gold of the Asian Championships in his fifth appearances. He had won a silver each in the 2005 and 2011 editions.
With this win, Gowda has booked a berth for next month's World Championships in Moscow as each of the winner in the ongoing Asian meet automatically qualifies for the global mega event.
After two days, China leads the medal tally with five gold, two silver and one bronze while India are in fourth position. Bahrain and Saudi Arabia are second and third respectively with two gold each.
Unlike yesterday, there was no rain today and spurred by the cheering sizable crowd at the Shiv Chhatrapati Stadium at Balewadi, the United States-based Gowda bought his win in a remarkable fashion after trailing to silver winner Mohammad Samimi of Iran (61.93m) till the third round.
Gowda holds the national record of 66.28secs while his season's best is 65.82m.
Later Gowda, who had also won a silver in the 2010 Commonwealth Games in New Delhi, said that today's win was the best achievement of his career. "Winning a silver in front of a huge crowd in the Commonwealth Games was one of my most memorable moments. But today's gold is right on top of everything," he said at the press conference.
