Is there any power supply that can feed up to 4 Raspberry Pi 5? Notice that 5A is mandatory since it works with 3, but usually drives an SD corruption.
Btw I didn’t find the regular R.Pi 5 power supply on the catalog.
Sorry I’ve found the regular Pi power but I’m still interested on the multi output one.
What you are looking for is a multi “PD Chargers”… What you really want is a PD Charger that supports the 5V/5A spec (which is an un-offical mode, but because of the RPI5, is supported on some chargers), if it doesn’t support that it’ll drop down to 5V/3A…
Unless another user finds a better option, the best i’ve found is this device:
Sadly it’s USB BC 1.2 which is (pre USB PD spec), it advertise 5V @ 2.4A. Must of the extra current is required for the downstream 4 x usb ports, what are you planning to populate in those ports?

Thank you for the tip but unfortunately Raspberry Pi 5 is superpicky and without 5v 5a you have a high risk of damage the filesystem of the SD (not physically but the filesystem)
I follow RasPi myths and misconceptions, this is one of the newer myths in the world of RasPi thanks for letting me know it’s finally spreading around.
While it may be true that your particular set of hardware add on choices is creating this problem for your specific system, it is not an actual problem to run a RasPi5 from 5V/3A.
The RasPi5 has a maximum specified current draw of 2.4A @ 5V @ 100% CPU load with no USB devices attached.
(Recommended PSU current capacity - Maximum total USB peripheral current draw in the official specifications table Recommended PSU current capacity Maximum total USB peripheral current draw https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#typical-power-requirements)
When the USB PD power supply only provides 3A, the RasPi5 automatically current limits the USB ports to 0.6A to prevent a brown out condition.
Since there are very few USB PD adapters that offer the 5v @ 5A, and none with multiple outputs, you can use the the power override configuration (usb_max_current_enable=1 in config.txt) to disable the USB PD limits and power the four systems via the 5V power connections on the GPIO header using any regular 5V @ 20A power supply. Watch out for wire resistance which can easily drop the 5V below the 4.75V absolute minimum, I design RasPi systems to keep IR losses down to where the drop never exceeds 0.15V).

I’ve learned that it is not a myth on the hard way. We’ve got a generic PD power supply and we have tons of corruptions after shutting down (properly) and turning on again, it never happen after a reboot but shutting down.
Once we connected the PIs to their original charger it didn’t happen again.
