From what I understand watts are given by the product of two parameters: volts times amps.Hello, I acquired a Raspberry Pi 5 about 15 days ago, but I have a problem that I can't fix:
My Raspberry Pi 5 seems to crash and shut down randomly.
I will detail my setup and all the tests I have conducted.
Setup:
- Raspberry Pi 5 (8GB)
- New (32GB) SD card with the latest Raspberry Pi OS 64-bit installed on it
- Argon NEO 5 NVME case with fan
- Crucial P3 SSD (4TB) with the latest Raspberry Pi OS 64-bit installed on it
- Power supply Anker 30W and/or Ugreen Nexode 300W with PD (100W port)
When I tested with my first 30W power supply, I had a low power alert on the desktop (in VNC). So I tested with my large 300W power supply with Power Delivery and I didn't see the alert appear with it. I thought it was a power issue even though I'm surprised because both have the necessary power and I absolutely do not want to buy a specific charger for a single device especially if it's USB-C, it makes no sense to me and goes against my ecological values of multiplying power supplies...
So, I tried several things that I found here on the forum or elsewhere on the internet. I want to point out that my problem occurs when I boot from the SD but also from the NVME, both have the problem.
For those wondering, I formatted my NVME to GPT to be able to use its full 4TB space because Raspi Imager writes the install in MBR by default (wtf so old school and 2TB limited…) then I cloned my two SD partitions to my NVME. It works, no problem booting from the NVME afterward but since the problem also occurs when I boot from the SD, the problem is not there.
To "accelerate" the problem, I noticed that when I used SFTP transfert with large files and the Raspberry Pi writes them (SD and/or SSD) it crashes faster.
I tried removing my NVME SSD to see if it was causing an issue with excess power, but my Raspberry Pi 5 also random crashes in that case.
I tested with a stock OS >> random crash
I tested to copy files >> crash imediatly!
Then, I looked on the software side, here are my tests:
Updated the firmware to the latest version (May 2024)
Edit this parameters :
sudo rpi-eeprom-config --edit
[all]
WAKE_ON_GPIO=0
PCIE_PROBE=1
BOOT_UART=1
POWER_OFF_ON_HALT=1
BOOT_ORDER=0x1
PSU_MAX_CURRENT=5000
Add this parameters :
sudo nano /boot/firmware/config
usb_max_current_enable=1
I also tried installing the tools offered by the manufacturer of my Argon NEO 5 case.
But nothing helps, my Raspberry Pi still shuts down randomly in less than 24 hours...
Please help!!!
For the Pi 5 the parameters needed are
- 5.1V
- 5A
Similar (and higher) watts can be obtained using more volts but less amps, for example. However, the Pi 5 can only make use of 5V modes.
Unfortunately, the combination of volts and amps needed by the Pi 5 are an optional part of the USB PD specification. Thus, a USB power supply can market itself as 100W, 45W and so forth without actually providing the 25.5W that the Pi 5 needs for correct operation.
I checked the marketing material at
https://www.ugreen.com/pages/ugreen-nex ... op-charger
but found not any list of volt-amp combinations. It's possible 5.1V at 5A is not available.
Are you able to order an official Pi 5 power supply in your country?
