I have a Picade 10" with Raspberry Pi 4 (4GB) (Jan 2021 firmware) and a Samsung 870 QVO SSD 1TB connected via a Sabrent USB 3.1 (Type-A) to SSD adaptor.
The Raspberry Pi power supply was fine when using an SD card but as soon as I introduce the SSD there isn’t enough power to boot, if I supply the screen and Pi with separate power then everything boots.
I am interested if other people have had similar issues and what they have done to resolve.
I can supply the unit from two power supplies or a power supply bank with two cables as an option, or I do have an option to power the SSD from another power supply source, all would work.
The single power supply bank with two cables seems a good choice.
Wow I just googled this issue and found your post. I have the exact same setup. The SSD arrived this morning and I am regretting not just using a 512gb micro SD card since it now won’t boot without using a second power supply for the screen. Did you find a solution? I have wondered if it is possible to get a more powerful PSU? I would really like this to work with a single power supply…
I’ve used what is probably the same Sabrent adapter, but not in a Pi setup.
Three things I discovered:
Different people experience different things, and I like the Sabrent kit but for me it wasn’t as reliable across my different machines as the Startech.com equivalent.
SSDs can draw a lot more current at peak than HDDs, and I’ve found consistently that my SSDs won’t run reliably off any of these adapters - sometimes they won’t connect, sometimes they drop out during transfers. The 1Tb SSD mentioned is rated at 4W burst mode on the specs page, which is 0.8A at 5V, but I searched around for pics of it and the rating on the label seems to indicate it can peak at 1.4A! For comparison, the 500Gb WD Black HDD sat on my desk is rated at 0.55A on the label. The USB adapter will draw its own current on top of that, so realistically you probably need to supply 1A for the drive+adapter alone. Bear in mind the Pi has a 1.2A limit for all USB ports combined.
When I used a Y-cable to power the SSD off two USB sockets the SSD worked fine for the brief moment before the Sabrent adapter went pop. The SSD and PC were fine, but the adapter was the weakest link.
If it works with a separate power supply for the screen that might be your safest, longest-lived option.
I’m wondering if this will work. Soldering a tap to the +5 and Gnd on the GPIO header to use for the monitor and them plugging the SSD into USB3. My thought is that would let the USB supply the full 1.2A since the monitor will be tapping the GPIO pins. I was going to supply the 5V with a 4A supply via either the USB C or the solder points on the Picade X.
hi you can power up the Display via the standart pi power connection
(you have to plug in the monitor via a usb c cabel in the usb c port of your pi 4) and thats it !!
full power for all usb ports, i test a hhd and serval sdd’s all work with no problems, full speed and no low voltage sign . i use teh original raspberry pi 4 power supply and use stock clockspeed
