The home side offered a huge aerial barrage to the Owls, who defended diligently and would have been well worth a win after Julian Borner netted his first goal for the club.
But who else were the star men on the day and who was below par? Take a look at our player ratings from the Welsh capital.
5. Morgan Fox - 7
Didn't put a foot wrong. Dealt with the threat of both of Cardiff's wide men well and contributed to the attack. One ball over the top in the first half was exceptional. Photo: JPIMedia
6. Sam Hutchinson - 7
When Hutchinson is at his best he moves the ball quickly at the right times and he did that at Cardiff. Shielded the defence expertly having picked up a needless early yellow card but tired late on. Photo: Steve Ellis
7. Adam Reach - 6
Not his most devastating display going forward, but another committed and intelligent all-round performance from Reach, who should take credit for his assistance to Palmer on the right. Photo: Steve Ellis
8. Barry Bannan - 7
What he does, he does as well as anybody in the division. When Wednesday were at their best on the night he was, typically, at the centre of it. A fine showing. Photo: Steve Ellis
