Ah, additional components. In addition to the SSD perhaps the HDMI connection is drawing current too but I have no knowledge of the electronic circuitry involved in an HDMI connection.
Certainly adequate power is needed but in my case I have a 3A supply feeding both the RPi and the Official Display through their individual power inputs using a USB power-splitter cable. I see no problems that I can associate with poor power. For example, the display shows the traditional 4 strawberry icons, one for each CPI, and no lightning bolt icon warning of an undervoltage condition. There are no power-associated warnings in the dmesg output.
I don't think we've ruled out the possibility that there is an unresolved configuration issue here.
...und Schöne Feiertage!

OK... 3A should be well enough. But OTOH: When I connected the Pi via the Pi power input, I got the same as you: 4 strawberries, no lightning - but additionally this strange effect pretending that there were no HDMI out. I don`t know for hard the specs of my current power adapter, but anyway: I remounted the old system (moode 4.2 on an old SSD in an SSD-USB adapter called Icy Box) with SD card only with /boot partition inserted and this config runs flawlessly for more than 2 years now and of course right now again. Very odd.
Also Schöne Feiertage for you (and everyone here) and: Bleibt gesund - Covid19 is a killer.
