Two goals from striker Steven Fletcher helped Sunderland claim their first away win in the Barclays Premier League this season at the expense of Crystal Palace.
Palace had the better of the opening exchanges but the Black Cats took the lead on 31 minutes when Fletcher smartly headed home from Patrick van Aanholt's cross.
The hosts were level on 55 minutes when substitute Wes Brown, who came on as a first-half substitute following an injury to Van Aanholt, diverted the ball into his own net. However, Jordi Gomez finished smartly from the edge of the area for his first BPL goal for Sunderland with 10 minutes left on the clock.
Eagles captain Mile Jedinak was dismissed for a second yellow card and Fletcher then sealed the three points that lifts Sunderland out of the relegation zone with his second in injury time.
Sunderland, who went into the fixture following an 8-0 defeat at Southampton and a 2-0 loss at home to Arsenal, moved up to 15th spot as a result, with Leicester City dropping into the bottom three below Palace on goal difference.
Poyet dropped goalkeeper Vito Mannone, with Costel Pantilimon making his first BPL start for Sunderland. Recent signing Anthony Reveillere was also handed his debut for the Wearside club.
Scott Dann returned to the Palace starting line-up after recovering from a knee injury, with Adrian Mariappa dropping to the bench in the only change to the side that drew at West Bromwich Albion.
Palace, who had an early penalty appeal turned down, showed plenty of endeavour early on but they could not convert that pressure and it was Sunderland who were in front with a goal from out of the blue.
Palace were caught out when Fletcher rose to guide a fine header inside Julian Speroni's right-hand post after he was picked out by Van Aanholt.
Fletcher tested Speroni with a right-footed strike and Santiago Vergini was denied by the Palace goalkeeper in first-half stoppage time as Sunderland grew in confidence.
Palace made a bright start to the second half and they were level nine minutes after the break courtesy of Brown. Zaha stood a ball up to the back post for an unmarked Marouane Chamakh and, although Pantilimon somehow kept out the striker's close-range header, the keeper was unable to prevent Brown from finding the back of his own net after Campbell had back-heeled the ball into his path.
Sunderland responded and Gomez fired home from 20 yards out to restore the visitors' lead, then Jedinak was shown a second yellow card four minutes from time after a clash with Gomez. Fletcher added his side's third in time added on with a neat right-foot finish.
Sunderland head coach Gus Poyet: "It means a lot [to win], it means more than what anyone can think. It's been a difficult couple of weeks, it looked like what we did at the beginning of the season had been thrown away."
"Fletch has been outstanding after that little spell out of the team. He came back really strong, showing why he is so important for us. Not just [against Palace], it's every day in training."
