I am using an Argon One M.2 case version 06182021V2.3, a Kingston SA400M8240G SSD, and a CanaKit 3.5 amp PSU. When I boot, I get the common low power warning on the desktop, but it is not consistently on. Using a USB tester, I noticed the USB 5vdc rail dips to 4.65vdc periodically and sits at around 4.8vdc. I get about the same level with the USB bridge adapter AND pulling it and using a powered USB 3 hub with a separate 4 amp PSU. I checked the specs on the SSD and they are actually lower than the WDS500G2B0B I have read about being successfully used for this. I am not sure what else I can do and looking for suggestions. The voltage on the power input through the USB-C connector is a steady 5.1vdc.
Also, there is a gold pin on the SSD board inside the case that appears to connect to the underside of the RPI4. What is this pin for? I looked at countless pictures of the Argon One M.2 via google and do not see that gold spring pin in any of them. I also googled it and cannot find any information also. It is labeled “H1” it looks like. At first I suspected it was to bridge the input 5vdc rail with the USB rail, as some invasive mod posts suggest in order to up the power to the USB ports without needing a HUB. But I am still having the power issue without the voltage drop on the main rail.
It is too bad that the SSD board does not take it’s power from the main 5vdc rail instead of the USB rail, or I suspect there would not be a low power issue in the first place.
Pictures attached, thanks!
