> I don't think that estimate takes into account the power savings (...) I don't think this is relevant. RPis cost is a critical factor in it's usefulness as a disposable toy computing platform, not web servers that need to run 24/7. Moreover, that cost is further worsened by the need to buy a custom power supply.
I have two RPi 4s that run 24/7 that I will likely replace with a 5. > Moreover, that cost is further worsened by the need to buy a custom power supply. But you don’t need to?
From RPi5's FAQ:
> 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.
As mentioned in a previous HN discussion, not only was RPi5 designed to require a nonstandard power supply, the official "high-quality" power supply for the RPi4 is also considerably underpowered at 15W at 5.1V-3A[1] while RPi5 stands at 27W at 5V-5A.
