It took less than six minutes for first-leg substitute hero Khvicha Kvaratskhelia to add a third goal to his tally in the tie, pouncing on an all too familiar Chelsea defensive blunder, this time by Mamadou Sarr.
Seven minutes later Bradley Barcola made it 2-0 on the night for the visitors with a fine finish to a PSG counter-attack and 19-year-old substitute Senny Mayulu added a third in the 62nd minute.
The home side rounded off a miserable night playing the last five minutes with 10 men after defender Trevoh Chalobah was carried off injured.
PSG will meet either Liverpool or Galatasaray in the quarter-finals next month.
