This is my build is the psu good enough to support overclocking and the overall build?
Yes that PSU (EVGA G2 550) is
You can overclock everything till all your components explode and the PSU is still fine for this build. :)

Anything can happen with computer components.. Even the best can fail. Your G2 has a 10 years warranty and EVGA IMO has one of the best customer service.
