New rpi5 + new official powersupply: "not capable" message

Wed Nov 08, 2023 4:01 pm

I've just received my raspberry pi 5 - 8GB version together with the original new 5A power supply.
After installing the Bookworm OS on an 32GB SD card and doing all update/upgrade stuff, I get a message in the upper right corner:
This power supply is not capable of supplying 5A
Power to peripherals will be restricted
All I have is the rpi5, the 5A power supply, a 32GB SD card and a Logitech Bluetooth dongle for my keyboard+mouse.

Ah, and at boot, I see:
power: supply: USB-C 3000 mA CC1 PMIC: reset normal
I do remember that before I updated all software, I once saw 5000 mA.
(perhaps it's some firmware issue?)

Check that the USB-C plug is inserted properly into the Pi. I had this warning once with the official 27W PSU because the plug wasn't fully in.

Thanks, yes I checked that a few times (removed, pluged in again), but that did not solve it.
However, taking the power supply out of the wall outlet (edit: and putting it back in) seems to have fixed it.
Probably the power supply has a small bug inside.

I'm having this issue as well. Official pi 5 power supply with a 4GB raspberry pi 5 + official case. I've tried unplugging and plugging back in and I've checked it's fully inserted into the wall socket and the USB-C port. No luck. :cry:

It might help to know if the issue is confined to one version of the PSU. Could posters please mention which of UK, Europe, North America, Australia plug type.

I have the same error but not with official power supply.
I tried with two power supplies that can provide many more amps than the raspberry needs but the message always appears.
I don't have any peripherals powered by the Raspberry Pi itself, I have an external disk with its own power supply and a 3D printer controlled via OctoPrint, so can I ignore this message?

EDIT: I solved following this post: viewtopic.php?t=357129#p2159525

This issue is now happening here.

"Official" Pi5 27W PSU (UK plug).

Message appears even when no USB devices are connected.

usb_max_current_enable=1 set in /boot/config.txt

The USB C cable is fully inserted.

Attaching two SSD's, a pen drive, a mouse, and a keyboard, seems to work fine, and vcgencmd get_throttled always reports 0x0.

Perhaps its a bug in the "Power" taskbar plugin ?

Despite having the 27W power supply, my new Pi 5 was continually reporting power supply problems on booting and disconnecting from wireless after a few minutes. I tried all the solutions above, but nothing worked. I had installed the OS from a previously cached image (for a Pi 4) using the Pi imager which also applied the stored "advance" options for setting wireless, etc. The power and wireless issues were immediately resolved when I downloaded a fresh OS image (for a Pi 5) and cleared the advance options from the imager. This may be a solution for some users.

I have the official UK PSU and tried to boot via usb and get the error that I don't have a 5v5a I had to edit the boot.txt to add the override.

Seems buggy.

I have the same problems at the moment using the official UK RPi 5 27W PSU with no peripherals other than the official active heat sync.

Booting without an SD card confirms that it recognises the PSU as a RPi one.

It's running bookworm, Linux raspberrypi 6.1.0-rpi8-rpi-2712 #1 SMP PREEMPT Debian 1:6.1.73-1+rpt1 (2024-01-25) aarch64 GNU/Linux

I've just added 'usb_max_current_enable=1' to /boot/firmware/config.txt but still showed the message after booting.

Any ideas how to debug or fix this?

You could keep asking your retailer for a replacement PSU and/or Pi 5 under warranty until you receive a pair which does reliably allow 5V @ 5A to be negotiated at power-up as is supposed to happen.

Determining why 5V @ 5A isn't always negotiated will require test equipment which only Raspberry Pi and/or their partners will likely have access to. One would need to determine what is happening to figure out what the resolution would be.

I built my own supply that is typical of several other project platforms I use with my PI projects..it is a 5V, 16 Amp (80 Watt) well-regulated supply wired to duplex USB-female (think back of your desktop) ports on a perforated breadboard mat. I dialed it up to 5.3Volts to compensate for any possible USB cable line-loss (6 ft USB-C cable). I get the same error at bootup saying it insufficient, while I beg to differ, that doesn't change that I get the message and I measured the output...still cranking out 5.3V with the Pi5 running....How do we fix/disable this?

I got my rpi5 recently. I have the same issue in Germany.
I am using the GeeekPi Raspberry Pi 5 Power Supply 27 W

I don't see a solution in this post. Are there any news?

You have to enable whatever the option is which tells the Pi 5 that your PSU is capable of delivering 5.1A if you don't support PD negotiation. This is a documented feature not a bug.
