General discussion • Re: Raspberry Pi 5 discussion thread

Nope the computer (PC) would stop and not work with the lower spec PSU in the computer, so a new one had to be bought.
Also with the PC before that it wouldn't boot with the old GPU card due to not enough power so even then a new PSU had to be bought, with a few extra connectors iirc.


But I do get you point about USB and that may depend how you read the release information
https://www.raspberrypi.com/news/introd ... erry-pi-5/
It does say that the peak CPU power draw is 2.4A. Also the HAT's and NVME was not out or announced, unfortunately they can't magic current if the CPU happens to wanting do draw that 2.4A

For users who wish to drive high-power peripherals like hard drives and SSDs while retaining margin for peak workloads, we are offering a $12 USB-C power adapter which supports a 5V, 5A (25W) operating mode. If the Raspberry Pi 5 firmware detects this supply, it increases the USB current limit to 1.6A, providing 5W of extra power for downstream USB devices and 5W of extra on-board power budget: a boon for those of you who want to experiment with overclocking your Raspberry Pi 5

I hope the documentation writers can check it is clear (now HAT and NVME/AI etc use is available)
though I just looked and the second FAQ for PI5 hardware page and the FAQ
https://www.raspberrypi.com/products/raspberry-pi-5/
does not specify USB at all.

Will my Raspberry Pi 4 power supply work with Raspberry Pi 5?
Raspberry Pi 5 is a higher-performance computer than Raspberry Pi 4, and you may have problems using an under-powered supply. We recommend a high-quality 5V 5A USB-C power supply, such as the new Raspberry Pi 27W USB-C Power Supply.
