PSG has now won the season-opening trophy on 14 different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck two times late to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen seasons.
