AFC Telford United beat FC United of Manchester 2-0 to win the Supporters Direct Cup.
The cup, which is competed for annually by fan-owned clubs, was secured with goals either side of half time by Andy Brown and Alex Meechan.
"It was a good performance against a useful side," the Bucks assistant boss Darren Read told BBC Radio Shropshire.
"Winning is a good habit, it's nice to lift a cup, and it posts a positive message for the club with local fans."
Scarborough beat Merthyr 2-0 in the inaugural secondary Supporters Shield.
Both games were hosted back-to-back at Telford's Bucks Head Stadium this year.
Telford's victory was earned when Brown, last season's top scorer, converted a Meechan cross on the half hour, with Meechan himself hitting the ball into the roof of the net following good work by Martyn Naylor minutes into the second half.
The invitational Cup was established by Supporters Direct in 2002, and the first ever final was won by AFC Wimbledon - who have won it three times.
FC United - the club formed by breakaway Manchester United fans - won it in 2006.
