The Parisian club has now claimed the season-opening cup on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, Marseille struck two times late to take a shock advantage. First, the English forward scored from the spot-kick, 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 moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen seasons.
