Maybe...maybe not. If the CPU did overheat, it may (or may not) have done more damage than just a re-pasting will correct. And there's an "art" about applying thermal paste (the key being to apply only enough to have a thin layer between the CPU and heatsink/fan assembly):
Also, you won't likely see any damage to a CPU by merely looking at the power supply. Just because it may have overheated doesn't mean that the power supply suffered any damage (though a severe overheating issue could possibly damage it---but in that case you'd likely see more evidence on the main-board itself).
