The King's XI scored 167 for three with IPL debutant S Marsh, son of illustrious former Australian international Geoff, belted 11 boundaries and a six in his first match of the tournament to enable the vistors register their third win from five matches in the tourney.
Marsh was ably assisted by Jayawardene, who hit six boundaries, including the match winning one, as the vistors comfortably went past the target with seven wickets in hand and seven balls remaining.
With this win, King XI Punjab have six points from five matches, while Deccan Chargers have only two points winning only one match and losing four so far.
Earlier, an unbeaten 76 by Rohit Sharma and a captain's knock of 48 by V V S Laxman enabled hosts Deccan Chargers to set a modest 165 run target for Kings XI Punjab in the DLF Indian Premier League(IPL) at the Rajiv Gandhi International Cricket Stadium here tonight.
Sharma brought some respectability to the total of hosts, who were in deep trouble, as wrecker-in-chief Piyush Chawla, claimed the prized wickets of South African Herschelle Gibbs, Laxman and Sanjay Bangar.
After winning the toss, King's XI Punjab skipper Yuvaraj Singh elected to field first, as teams chasing a target won eleven of the 18 matches here. Deccan Chargers captain V V Laxman along with wicketkeeper-batsman Adam Gilchrist gave a solid start for the hosts, before Irfan Pathan got the much-needed Breakthrough for the Punjab team by uprooting the middle-stump to dismiss Gilchrist for six runs.
Gilchrist, who made a record 42-ball century against Mumbai Indians in an earlier outing, disappointed the home crowd, as he swung the ball from the crease without using his footwork.
South African Herschelle Gibbs, who came in place of Australian hard-hitter Andrew Symonds, scored just seven, before he was dismissed by Piyush Chawla when Goel took the catch at mid-wicket.
Chargers Captain V V S Laxman missed his half century by two runs when he mistimed a flighted delivery by Chawla to be caught by Yuvaraj at cover point.
Pakistani's Shahid Afridi(13) failed to perform again as he got a top-edge off Gagandeep Singh's delivery and Yuvaraj took a brilliant catch, falling down on to his back.
Hosts were in deep trouble as Y Venugopal Rao(1) was ran out by Punjab wicket-keeper Sangakkara due to mis-understanding with batsman R G Sharma at the other end. Chawla made no mistake in throwing back the ball to Sangakkara to complete the formality.
Bangar(3) was the next man to go when he tried to hit Chawla over long-on, but S Sreesanth, dived forward to hold a well-judged catch.
The problem for the home team compounded when Sreesanth dismissed D N T Zoysa(1), uprooting his middle stump with a full-length delivery.
Pathan dismissed Kalyankrishna(3) the other wicket that fell when Marsh took a brilliant catch at backward point, diving horizontally to his right.
Deccan Chargers got their first victory in the tournament against Mumbai after three sucessive losses, while King's XI, won won two of the four matches played so far.
