Murray won gold in the men's singles, overcoming his Wimbledon heartache to beat Roger Federer 6-2 6-1 6-4.
"Come US Open time, I hope this will have given me the confidence to go in there and believe in myself a bit more than I have in the past and give myself a shot at winning there," said Murray.
"I've played very well at the US Open in the past. It's a surface I like playing on and I always enjoy playing on Arthur Ashe court. I hope I can have a good run there.
"I have to be careful over the next two weeks and not do too much because it's been a long couple of months already."
Murray is scheduled to compete in the Toronto Masters next week but is now expected to pull out following his recent heavy schedule.
