Kevin Weekes made 31 saves, New Jersey scored three goals in the first 12 minutes and the Devils recovered from their only loss in three weeks to beat the Thrashers 5-1 on Friday night.
Zach Parise and John Madden each had a goal and an assist for New Jersey, which scored two goals short-handed. The Thrashers were 0-for-7 on the power play, leaving them 1-for-32 in the past nine games.
"When you go minus-2 on your power play, it's not a good sign," Thrashers coach John Anderson said.
Anderson said "it could have been a different game" if his team had "been sharper" on the power play, but the Devils threatened to turn the game into a rout in the first period.
Travis Zajac scored 4:34 into the game, Madden scored short-handed on a shot over Kari Lehtonen's glove and David Clarkson scored in front of the net for a quick 3-0 lead 11:42 into the game.
Colby Armstrong scored Atlanta's only goal early in the second period, but the Devils shut down any hopes of a comeback by answering with a power-play goal by Parise and Brian Gionta's unassisted goal, also short-handed.
"Those (short-handed) goals were great," Clarkson said. "The guys on the power play did a great job. Our special teams worked hard."
The Devils won three nights after a loss to Washington snapped their winning streak at eight games. The Thrashers have lost five of six.
Though New Jersey leads the Atlantic Division and the Thrashers are last in the Southeast Division with 41 points, second-lowest in the NHL, the Devils felt they had a point to prove.
Atlanta's only shutout win of the season was a 4-0 victory by Lehtonen at New Jersey on Jan. 8. Brent Sutter said the loss may have been the worst in his time as New Jersey's coach.
"This was big," Clarkson said. "These guys beat us the last time we played them.
"We gave everything we had right away."
Sutter said his team "did a good job," though there was no scoring after the second period.
The Thrashers had an 18-3 advantage in shots on goal in the third period, to finish with a 32-31 edge, but didn't score.
Sutter, who pulled goalie Scott Clemmensen in the second period of last month's loss to the Thrashers, gave Weekes his first start since Jan. 16.
