New PSU for my build

So i currently have a tx950 that seems to be faltering., I used to have super stable overclocks on my cpu and had to back it to stock to get stable. Now yesterday i had to return my gpu to stock so now im looking at new ones. So any suggestions for a i7 4770k oc'd with gtx 780 oc'd an h100i a few drives and and the rest. Thanks for your time.
