The Parisian club has now claimed the season-opening cup on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the French Cup holders after the French winger found the net early on.
However, the southern French side fired two times late to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
