Cristiano Ronaldo matched a Champions League record by scoring in his ninth consecutive game in the competition on Tuesday.
Ronaldo headed home Lucas Vazquez's cross in the 51st minute at Paris Saint-Germain to put Madrid in full control of the round-of-16 tie before they won 2-1 to advance 5-2 on aggregate.
The goal allowed him to equal the record held by his former teammate Ruud van Nistelrooy, who also scored in nine straight Champions League games for Manchester United in 2002-03.
Ronaldo has scored 14 goals during his streak, which stretches back to last season's final victory over Juventus, while Van Nistelrooy netted 12 in his nine games with at least one goal.
This campaign, the Real Madrid star leads all scorers with 12 goals, a feat accomplished only nine times -- and five of those nine were by Ronaldo.
Ronaldo has 22 goals in his last 13 Champions League games and 117 in his career. He has 57 goals in the knockout stage -- 19 more than his closest rival, Barcelona's Lionel Messi.
Vazquez's assist was in his team-leading 11th in all competitions this season.
Madrid reached the quarterfinals for an eighth straight season, going one better than their own club record set from 1999-2004, though they still trail Barcelona's ongoing record, which could reach 11 years this season.
Real's 16th appearance in the Champions League quarterfinals matched Bayern Munich for the most all-time.
For PSG, the result marked their first loss at home in all competitions for nearly two years -- ending a 51-match home unbeaten streak, with their last defeat at Parc des Princes coming March 20, 2016, against Monaco.
They failed to reach the quarterfinals for a second straight season after last season's defeat to Barcelona. It also marked the fourth straight season that PSG were knocked out by a Spanish club.
