The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring in the opening stages.
However, the southern French side struck two times in the closing moments to take a shock advantage. First, the English forward scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital equaliser in the final seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
