The new 27W USB-C PD (Power Delivery) Power Supply will deliver a maximum of 5.1V, 5A enabling the Raspberry Pi 5 to power a wider range of peripherals. The total power drawn from the four USB ports on Raspberry Pi 5 is limited by default to a nominal 600mA; this limit is automatically increased to a nominal 1.6A when the USB-C PD Power Supply is detected.
The USB-C PD Power Supply is also capable of delivering 3A @ 9V, 2.25A @ 12V, and 1.8A @ 15V to PD-compatible products, making it a good cost-effective power supply for many general-purpose, non-Raspberry Pi use cases.
