Mackay's men made history on Sunday as they became the first Bluebirds side to win 10 successive home games with a 1-0 win over Sheffield Wednesday in front of over 20,000 fans - a figure they have topped in every one of those 10 victories.
And the City chief believes the impact of those supporters as well as the ability of a squad that includes the likes of Peter Whittingham, Craig Bellamy, Craig Noone and Tommy Smith have been huge factors in earning his side a place in the record books.
"Our fans come here every week and put an atmosphere into this stadium that can make teams tentative from the kick-off," he said. "You have seen that a few times when we've caught teams cold this season.
"I have got exciting players that want to play football and exciting players that want to go forward and pass the ball.
"That allows our fans to create an atmosphere which means teams come here knowing they are in for the game. And that is very pleasing.
"It (the record) is something I am very proud of and something that builds momentum."
