PSG has now secured the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the match between the French league winners and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck two times late to take a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial leveler in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last thirteen years.
