Can you recommend one? I seem to be having this problem. Using the official 3A power supply but anytime I plug another USB device my server goes crazy. Will the “Raspberry Pi 27W USB-C Power Supply” on Pi hut solve the problem for a Pi 4b?
I use a USB hub with it’s own power supply. No issues with my SSD (or anything thing else) connected to the pi or hub. I have the Powered USB Hub, RSHTECH USB 3 Hub with 4 USB 3.0 Data Ports + 1 USB Fast Charging Port, USB Splitter with 24W(12V/2A) Power Adapter and Individual On/Off Switches.
I see. That’s a nifty way of avoiding the problem. Unfortunately I am Using a NESPi 4 case and the SSD is supplied from the Pi’s power supply. I am getting another power adapter. I have a powered USB hub but that will be for anything else I connect to the Pi.
If someone is looking for a way within Rasberry OS. With the SSD already connected. Here is the way and you have to follow this guide just after Check the EEPROM version

Download the current Image HAOS like
wget https://github.com/home-assistant/operating-system/releases/download/11.3/haos_rpi4-64-11.3.img.xz -
Find your SSD with
lsblk
Mine was calledsda. -
Use xzcat and dd to write the image to the SSD, even with progress
xzcat haos_rpi4-64-11.3.img.xz | dd of=/dev/sda bs=4M conv=fsync status=progress
Reboot and you are done. 
I think you’ve saved me some trouble. I’ve fought with the issues you’ve described above and was looking for an answer, I think I’ve found it. Kudos to you. I’ve searched the house and no 3A PSUs, 2.4A was the biggest I had and still same issue. I’ve ordered a 3A now.
