just because a human feels pain at 50-60°C does not mean plastic or hardware does.

I always check power connectors - at least when newly attached.

The reason why is to make sure they are NOT getting hot or even too warm. Or warm at all, for that matter. Power cords and thus their connectors should be sized properly to take the expected load (current flow) just to ensure they don't overheat.

If you think this is silly, think again. Then go check all your connectors. If they are warm to the touch, investigate further.

i have built a hundred PCs, have a whole rented storage unit full of hardware had at least 30different PSUs and i never even came to the idea to "touch my PSUs power connectors"...
must be a imaginary problem.

Look it is like a CPU - if your heatsink is too hot to touch the CPU is likely throttling. The power plugs don't know how to throttle.

But you are correct in that it is quite rare for the power cords or power plugs to overheat, as they normally come matched to the power supply. The few situations I have seen it happen this was actually the fault of the outlet which had poor contact. Maybe the OP changed the outlet they were using after replacing the PSU and now they see the plug heat up ?

Then I won't hold your obvious youth and lack of experience against you!

For sure, we are NOT talking about the DC power connectors on the output side of the PSU. This is about the PSU's AC power cable where it plugs into the wall - or in this case, into a power strip.

Have you never heard of overloading a power outlet? This is particularly a problem with power strips and extension cords and even more of a problem this time of year.

Having said that, when one has been around electronics long enough, it is likely they have run into a device that is faulty and drawing excessive current that may go unnoticed, until too late. One way to check that is to feel the power cable at the outlet. If you don't ever do that, I recommend you make it a habit and hopefully, you will never feel a hot plug.
