How do?

Had a look through n used the search function but couldn't find an answer so i am asking. Sorry if its been answered recently n i havent found it.

Anyhoo- I have a 3x9 gear setup on my bike and my shimano chain that came with it has snapped. i used a quick link to fasten it together n a couple of weeks later it snapped again, so i put in another quick link. I have only had the bike 6 months so this seems a bit excessive. I went to my LBS and they gave me ( i say gave, i had to pay) a KMC x9 chain. I fitted this chain yesterday n went for a spin last night. I have found that whenever i try to put any power down the chain skips but just spinning normally it is ok. Something i noted is that the new chain has slightly bigger links on it but is meant to be a 9 speed chain. Any ideas on the problem or why the shimano chain and the KMC chain are different link sizes?
