Will this PSU be good for an i5-2500k build with a 560 ti?

I wouldn't risk your hardware with a cheap PSU. Get a Corsair or Seasonic, the Corsair VX550 is a very good PSU and will be plenty for your needs, as well as being quite affordable.

If you plan on going SLI at some stage I suggest you look at the Corsair TX750 or bigger.

You're looking at 550-600W for single and 750W for SLI, as Smoke said. Corsair and Seasonic aren't the only good units though, anything on the Recommended PSU sticky will do you fine. Also, sites like http://www.jonnyguru.com have excellent PSU reviews.

There are a few PSU'd out there in that price range that will be "ok" for your needs. Here are a few that i found backed up by legit reviews:

I would take any of these PSU's over The one you linked. Here is a good site with review links.
