Power supply to mobo cable not even 1 mm of wire insulation off now

Hey guys

English is not my foreign language. I apologize for any bad grammar and stuff.

I'm in real trouble I guess. I wanted to clean my ps4 pro today and something happened.

After removing the case I wanted to take out the power supply. So, after I was about to pull out the power supply cable I kinda screw up and my needle nose pliers slipped off and came against the cables. Well, it wouldn't be a big deal but some wire insulation ripped off. Not bad, just superficial and a tiny spot is showing some stripped wire.

I don't know what to do now. The ps4 is running fine like nothing happened. I used some duct tape to isolate the area. I also searched the Internet for a replacement but found nothing. All the cables are black, and mine is white.

My Playstation is the CUH-7216B.

Can anyone help me? Would liquid rubber insulate the area better? It's pretty far up the plug.

I really have no idea what I'm supposed to do and if it's dangerous to use my Ps4 now. Every opinion and advice is welcome.

Best regards
