An Ulster University Jordanstown side featuring Donegal inter-county stars Ryan McHugh and Paddy McBrearty and Tyrone's Mark Bradley were expected to pose a stiff test at home to Sigerson Cup holders UCD and there was just a point in at the break - the visitors up 0-08 to 0-07.
However, the reigning champions ran riot in the second half, scoring a goal through Conor McCarthy as Dublin defenders Jack McCaffrey and Mick Fitzsimons helped to hold the hosts to just two more points in a comfortable 1-18 to 0-09 victory.
UCD will face UL or DIT, who meet tomorrow (2pm), in the semi-finals.

DCU are out however, after an extra-time defeat at home to St Mary's.
Roscommon's Enda Smith rattled the net twice for the favourites but Tyrone 2015 U21 winner Cathal McShane equalised late on to level at 2-10 to 1-13.
Brian Og McGilligan scored Mary's second goal early in extra-time and the visitors held on to win 2-14 to 2-13 and claim a notable scalp.
They will meet UCC in the semi-finals.
UCC needed extra time to get by IT Carlow in Carlow, Cork panellist Michael Hurley scoring the hosts goal as it finished 1-06 to 0-09 after normal time.
Another Corkman, Brian O'Driscoll got the only point of the additional time to seal the 21-time winners' progress.
