The Owls turned in a superb display at Meadow Lane on Saturday as goals from Ryan Lowe and Gary Madine sealed victory over Notts County.
Both Lowe and Madine struck after the break to make it three wins on the spin for Wednesday, who continued their impressive run under new manager Dave Jones.
Lloyd Sam netted a late goal for the hosts to set up a tense finish but Wednesday held on for a crucial three points in Nottingham.
The Owls boss named the same side that picked up a 3-0 win over Bournemouth seven days prior.
With Wednesday facing a County side had won five of their last six games, it was to be no easy task as Keith Curle's men created the first opening after two minutes.
The Magpies broke quickly upfield with Alan Judge leading the charge and the midfielder's cut back found Jon Harley who blazed over the bar.
Wednesday, though, were looking dangerous down the wings as Mike Jones chipped in a delicate cross that Rob Jones headed over the crossbar.
That was the Owls captain's last contribution, however, who picked up an injury in the aerial collision and was replaced by Miguel Llera.
The game settled into a fairly even affair at the midway point in the opening period.
Judge then fired a speculative effort from distance that cleared the crossbar before Michail Antonio came within inches of breaking the deadlock, five minutes before the interval.
Following a long clearance upfield by Madine, Antonio muscled past his marker before driving into the area but struck the wrong side of Stuart Nelson's near post.
From that point, Wednesday began to turn the screw as the first half drew to close.
A long throw from Antonio landed to Bennett at the back stick who saw his strike blocked at the last by Kieron Freeman.
Wednesday began the second half in the same vein and took the lead on 53 minutes to the delight of the full away following from Sheffield.
Antonio was the architect, as the on-loan Reading winger breezed past three challenges before playing a perfect ball across goal for Lowe to apply the finishing touch.
The Magpies launched an immediate attack from the restart but Danny Batth was on hand with a superb piece of defending to thwart Jeff Hughes at the near post.
Llera then saw his free kick tipped wide by Nelson before Madine strengthened Wednesday's grip on the game with an outstanding goal from the edge of the area.
Lewis Buxton's throw in found Madine, who turned sharply on the edge of the area before unleashing a fierce drive into the bottom corner.
Substitute Chris O'Grady almost benefitted from a poor clearance from County keeper Nelson but Damion Stewart made a key block to spare his team mate's blushes.
County debutant Sam then set up a nervy finish, as he connected with Judges' free kick to halve the Owls' advantage.
Four minutes added time was indicated but there was to be no further drama at Meadow Lane as Wednesday posted a vital victory.
