The power supply is available in two colours: white (T5875DV) and black (T5989DV-RS), and has been specifically designed for the launch of the third-generation Raspberry Pi board, as it requires more power – approximately 2.5 A – to support the Broadcom BCM2837 processor chipset that powers the Raspberry Pi 3. The Broadcom chipset comprises a quad-core ARM Cortex-A53 based processor running at 1.2 GHZ, together with integrated short-range connectivity including 802.11b/g/n wireless LAN and dual-mode Bluetooth 4.1 Classic and Smart (Bluetooth Low Energy) profiles.

As sole manufacturer of the officially approved Raspberry Pi 3 power supply, Stontronics has designed the device to meet the updated and expanded US Department of Energy (DoE) Level VI Energy Efficiency requirements, which became effective on February 10, 2016. The new DoE standard mandates more stringent energy efficiency levels for a greater number of external power supply types. According to DoE estimates, these new requirements will save consumers up to $3.8 billion and cut emissions by nearly 47 million metric tons of carbon dioxide over 30 years, which is equivalent to the annual electricity use of 6.5 million homes.

Key electrical characteristics of the Raspberry Pi 3 power supply include: an output voltage of +5.1 V; load current of 2.5 A (nominal); output power of 13 W (nominal); output regulation of +/-5%; and protection features including short circuit, over current and over voltage. Other specifications include dimensions of 73.2 x 45.1 x 35.1 mm, an operating temperature range of 0 to +40°C, and an MTBF of 50,000 hours. Also included with the power supply is a 1.5 m USB-B lead to connect to the Raspberry Pi board.

Both colour variants (T5875DV / T5989DV-RS) of the new Raspberry Pi 3 power supply are now in stock via RS Components and Farnell.
