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.https://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238480Wed, 30 Sep 2026 18:41:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6748b2c4-d3fd-4dd6-bad3-ce10723380beAndrew JWhen I get home I’ll dig it out.

It is a PI5 case rather than a generic one.https://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238478Wed, 30 Sep 2026 18:25:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4bfafd43-9b38-439b-9098-aff673783d5eralphjyI 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?https://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238474Wed, 30 Sep 2026 17:05:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5438c705-882b-4ff6-9647-ee0e104b0512veluv01Here's the USB Power Delivery WhitePaperhttps://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238473Wed, 30 Sep 2026 17:04:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:7123f20f-256a-4aec-82c2-b4db2e9f7d19veluv01https://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238472Wed, 30 Sep 2026 16:37:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a4834820-f187-44d6-b8f3-6765cf0e96c5ralphjyIf 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).https://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238471Wed, 30 Sep 2026 16:27:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:19cc460e-d0a9-400f-bd2b-ef719f0ce209chekovNot sure if this will help get to the root of this particular problem, but they do discuss some methods to measure power consumption here: forums.raspberrypi.com/viewtopic.phphttps://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238470Wed, 30 Sep 2026 15:54:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:c6cb1990-d242-43c4-8f66-a24b7368ab1fcstantonThe problem might be with the enclosure, sometimes they do not expect higher power pull which has changed depending on what PCIe standard they expect/support.https://community.element14.com/products/raspberry-pi/f/forum/57316/raspberry-pi-5-randomly-reboots-when-powering-an-ssd-over-usb/238469Wed, 30 Sep 2026 15:44:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9cfc89db-e196-465c-9172-089e38e92f40Andrew JThanks. Must be some other incompatibility then; I just couldn’t get to the bottom of it and because I was using it for HA, which I got thoroughly #}%&£@ off with, I gave up on it.

A supposedly compatible enclosure with compatible NVMe SSD and it was very unreliable. I was running Home Assistant, which would frequently crash with no logs or other information.

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?

Since the main goal is making it easy for friends who aren’t familiar with terminal commands, a simple launcher that starts directly into the SNES emulator and keeps the configuration minimal sounds like a good approach. A small Python script for handling startup and controller configuration could make the whole setup much more user-friendly as well.
