I am building my first rig that will have an i5 4670K and a GTX 780 both I want to overclock. What size psu would I need to handle that? Would a 620w seasonic s12ii be sufficient? Thanks!

Estimating 260W for GPU and 200W for the rest of the system, gives about 40A needed on +12V rail.
This PSU can provide up to 48A, and at 40A it will be loaded to 85%. This looks reasonable.
