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,

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.

When I get home I’ll dig it out. I formatted it with HAOS but presumably the underlying config is common.

I'm not that confident in all PI5 supplies being the same. The 5A sucker is much larger and weightier than the typical Pi power supply. I have a variety of PS kicking around and the size I noticed.

I'm not saying you are wrong but PS for Pi's has always been contentious issue for me.
