PSG has now claimed the season-opening cup on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck two times in the closing moments to take a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho 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 dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
