Once I had found out how to insert the PCIe cable into the V3 board I finished setting up the case exactly as instructed. However it failed to boot and I soon found out that it was a lack of power to the board…
I wondered if it was a problem with the 27 watt genuine power supply so I powered the Pi up again using the power supply for my Samsung Galaxy S23 phone and it worked OK.
I the used the apparantly defected 27 watt power supply to power up my other Pi 5 and it powered up successfully.
Why does the 27 watt power supply work correctly with the bare Pi 5 but not with the Pi 5 in the Argon V3 case?
What is the solution?
I have read some of the other threads but they too complicated for me to come to anty solution.
