My Ps4's power cord was always loose and always sloping down. Today I pulled it out and pushed it in harder so that it is no longer so loose. But now I have a guilty conscience that the Ps4 has been damaged because I pushed the cable in hard.
So far and tight in until it can't go any further. What's going to break in the process?
As long as you don't shoot it in with a hammer, nothing can break
The plug of your PS4's power cord should be firmly and straight into the connector provided. As long as you put the cable neatly into the connection with reason and feeling, so that it does not fall out by itself, it should be fine.
You should take a look at whether it is stuck in there, otherwise check whether the plug of the cable or the connection of your PlayStation show damage or other defects, which could be the reason why it is loose.
You should always be careful with technology, otherwise: Probably not.
