I have a RPi 5 with the SSD adapter. I have a 1 T byte Kingston SSD. The RPi 5 and SSD does run at times. I’m running it now. But it took four attempts to get it booted. I started with a 3 amp official power supply. The your power source doesn’t have enough power to power peripherals. Which I took to mean no power to the SSD.I then ordered the next up 27 W and still had the issue. I’m now using a 45 W official power supply and it still has a problem booting. Just no not enough power message. Suggestions?
Even though you’re using a 45W power supply, the Pi 5 requires USB Power Delivery (PD) to negotiate higher voltages (like 9V or 12V). Make sure the USB-C cable is a high-quality PD-rated cable.
Ensure the power supply supports USB-PD and is handshaking properly with the Pi 5.
The 45 W power supply is the official Raspberry Pi 45 W USB-C. The other power supplies used are all Raspberry Pi official units. The problem reminds me of early switching power supply inrush issues when first switched on. The SSD adapter added but the keyboard is a wired and the display is an HDMI the mouse is a bluetooth unit. With the earlier power supplies the boot sequence seemed to stumble when the bluetooth or wifi was accessed. At times the background screen would show and when I tried to move the mouse the screen would go white with the trash and one folder icon then to a flashing dash upper left corner. It might help if I add that the micro USB card has been removed and the OS is from the SSD. So when booting up if the RPi 5 disables peripherals it stops the boot sequence.
Thanks for responding.
