If this is United, it is totally not enough. SFO is famous for the stratus delay that can severely affect short haul domestic flights into SFO. I'd guess there is a roughly 30% chance of a 1-hour delay and 10% chance of 2-hour delay. UA's SFO-HKG is badly timed to connect from short-haul, especially Express from minor cities. Anything arriving after 0900-0930 is at risk. That's why I won't take anything that arrives after 0945 for there 1 pm flight if I cannot be delayed by 24 hours.
