He set for a comfortable victory after an impressive start but White showed his resilience and battled back well.
A missed black off the spot in the fifth frame gave White the chance to close the gap to one and he showed his potting skills to make it 3-3.
A fluke on the yellow in the seventh frame proved crucial as O’Sullivan regained his lead.
There only looked to be one winner from then as O’Sullivan made sure of his place in the next round.
