I have apparently a good quality 2.5A power supply
Considering that you are here complaining of power problems, I find that statement questionable. How do you know it's a "good quality" power supply? Have you load tested it? Exactly which "good quality" power supply are you using, and does it use a separate micro USB cable or have a built-in cable?
Many so-called "power supplies" for Pi computers are really just re-purposed phone chargers, and phone chargers are lousy power supplies because they often have poor voltage regulation. In addition, most standard micro USB cables aren't designed to deliver much more than 500mA of current without voltage loss. So you not only need a proper power supply with good voltage regulation, you need a power cable with thick, low resistance wires and a high amp rated micro USB plug.
If your power supply requires a separate micro USB cable, try a shorter cable, or a cable designed for charging a phone or tablet. And if that doesn't help, get the official Raspberry Pi Universal Power Supply
I've run several Pi 3B and 3B+ computers from SSD
and hard drives with no power issues using the official Raspberry Pi Universal Power Supply
. The official power supply outputs 5.1V at up to 2.5A and has a built-in micro USB power cable with fat 18 AWG power wires.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
