OC sudden instability

I had my 4770k OCed to 4.5GHz for quite some time. Not long ago I added another SSD to my system 850 EVO 500GB and since that day I encountered several blue screens. At first I though it is faulty SSD but benchmarking it and testing it resulted in fine results so I removed OC from my CPU and I encountered no problems since.

Is it possible that adding SSD to system made CPU put resources into before unused PCI lanes which resulted in instability of the OC?

just increase core voltage

Is the SSD over SATA, M.2, PCI-e... 

Fine you want the PSU tier list? Have the PSU tier list: https://linustechtips.com/main/topic/1116640-psu-tier-list-40-rev-103/

Might not be the answer you want to hear but probably need more voltage like he said... possibly slight degradation since you said its been at 4.5 for awhile. Its not uncommon to have to bump vcore up .0255 after a few months or years to keep an OC stable.

Mmmm. I will give it a shot. Hopefully I won't need to remove it during summer. I would like to keep all season OC and mine was already on the edge during summer.

Have you considered that MAYBE your OC is interfering with the controllers somehow? It is a possibility dial back your OC a bit it shouldn't hurt your performance so much
