Raspberry Pi 5 randomly reboots when powering an SSD over USB

I’m using a Raspberry Pi 5 with an NVMe SSD connected through a USB 3 enclosure. The Pi works normally when the SSD is disconnected, but occasionally reboots when the SSD is under sustained read/write load.I purchased this one in Italy, so it might function differently.

The power supply is rated at 27W, and the issue seems more likely to happen when the CPU is also under load. Has anyone seen this with the Raspberry Pi 5, and would using a higher-rated USB-C supply or a powered USB hub be the recommended solution?

Thank you

best,

If you are already using the official RPi 27W supply, then you can't get any more power through the USB-C input. I think it would be worth trying a powered hub to isolate the problem. A single USB3 port is limited to around 900mA which might be exceeded by your NVMe SSD during peak operations. Also, be careful of using higher wattage supplies like the MultiComp 30W which only supplies 5V at 3A (the higher wattage is for higher voltages in the USB-PD).

I should have added that you need to verify the USB power capability of the ports on the hub and enclosure. The best solution is probably to use a self-powered enclosure. Does yours have the ability to plug in an external power supply?

IIRC the power supply plugs into the enclosure to power everything. It is a PI5 case rather than a generic one.
