This doesn't resolve the Raspi 4B's internal power budget limitations of its USB ports. An original Raspi power adapter for the Raspi 4B is totally sufficient, a Raspi 5 power adapter definitely on the safe side. Your 65W power adapter is way over the top and maybe better suited for some other device, but of course it doesn't hurt.

You may never experience a problem with your Samsung T7 SSD attached to your Raspi. But there's no guarantee. From few pictures of this device's side opposite to the connection port it's labeled for a power consumption of DC+5V and 1.5A (likely the maximum rating at worst case), but that would definitely exceed the Raspi's power budget.

I'm just saying what is a not well known and frankly a little bit annoying limitation of the Raspi 4B.

A possible remedy is to use a sufficiently self-powered USB3 hub in-between.
