PSG has now claimed the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger opened the net early on.
Yet, the southern French side struck two times late to take a shock advantage. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
