Ondrej Pavelec made 26 saves in the win, which allowed Atlanta to move into first place in the Southeast Division standings. The Thrashers have gone 3-0-2 in their last five games.
The Devils, meanwhile, dropped their eighth straight road game.
Former Thrasher Ilya Kovalchuk got New Jersey's lone goal and Martin Brodeur lasted only two periods before being pulled in favor of Johan Hedberg after allowing four goals on 15 shots.
