PSG has now claimed the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match between the French league winners and the French Cup holders after Ousmane Dembele opened the net early on.
However, the southern French side fired two times late to seize a shock advantage. 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 breathtaking turn of fortune, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 seasons.
