新款原廠電源 5.1V 5A Raspberry Pi 5B 27W USB-C PD Power Supply - Black （黑色）Type-C 美規
原廠 Pi5B電源：5.1V 5A，27W USB-C PD Power Pi 5 黑色 Black
原廠 Pi5B電源 5.1V 5A Raspberry Pi 5 27W USB-C PD Power（黑色 Black ）
The black Raspberry Pi 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.
Ｂ．原廠電源（新款5.1V 5A）5v 3a也能用：
Raspberry Pi 5 將使用 5V 3A USB-C 電源，但要釋放最佳效能，您需要使用 官方 27W USB-C PD 電源，特別是如果您打算為 USB 驅動器等耗電週邊供電。
ｐｓ．5V 3A 15w 通常仍足以驅動滑鼠、鍵盤和其他低功耗週邊裝置。（超過電壓須更換5A 電源）
Raspberry Pi 5 consumes significantly less power, and runs significantly cooler, than Raspberry Pi 4 when running an identical workload. However, the much higher performance ceiling means that for the most intensive workloads, and in particular for pathological “power virus” workloads, peak power consumption increases to around 12W, versus 8W for Raspberry Pi 4.
When using a standard 5V, 3A (15W) USB-C power adapter with Raspberry Pi 5, by default we must limit downstream USB current to 600mA to ensure that we have sufficient margin to support these workloads. This is lower than the 1.2A limit on Raspberry Pi 4, though generally still sufficient to drive mice, keyboards, and other low‑power peripherals.
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.
It should be noted that users have the option to override the current limit, specifying the higher value even when using a 3A adapter. In our testing, we have found that in this mode Raspberry Pi 5 functions perfectly well with typical configurations of higher-power USB devices, and all but the most pathological workloads.

【常見問題】：
Ｑ１：舊版的 Raspberry Pi 作業系統可以與 Raspberry Pi 5 搭配使用嗎？／Will older versions of Raspberry Pi OS work with Raspberry Pi 5?
答１：您的 Raspberry Pi 5 需要最新版本的 Raspberry Pi OS Bookworm。Bookworm 將於 10 月中旬推出。／You will need the latest version of Raspberry Pi OS, Bookworm, for your Raspberry Pi 5. Bookworm will launch in mid-October.
Ｑ２：我的 Raspberry Pi 4 電源可以與 Raspberry Pi 5 搭配使用嗎？
答２：Raspberry Pi 5 是比 Raspberry Pi 4 更高效能的計算機，使用電源不足時可能會遇到問題。我們推薦高品質的 5V 5A USB-C 電源，例如新款 Raspberry Pi 27W USB-C 電源。
Ｑ３：我的 Raspberry Pi 5 適合我的 Raspberry Pi 4 外殼嗎？
答３：Raspberry Pi 5 不適合 Raspberry Pi 4 保護殼。我們推薦適用於 Raspberry Pi 5 的 Raspberry Pi 保護殼，旨在協助您充分利用我們最新的電腦。
Ｑ４：樹莓派5需要主動散熱嗎？
答４：Raspberry Pi 5 比上一代 Raspberry Pi 更快、更強大，而且像大多數通用電腦一樣，它在主動冷卻的情況下表現最佳。適用於 Raspberry Pi 5 的 Raspberry Pi 外殼及其整合風扇是提供此功能的一種方法。

Our accessories for Raspberry Pi 5 are carefully designed to make sure you get the most from your computer
Ａ．原廠外殼（附風扇）紅白外殼、草莓外殼－－另購
裝扮得時尚，同時保持涼爽
新的冷卻選項可確保您的 Pi 5 在負載下保持舒適，Raspberry Pi 5 官方保護殼 現在配有內建風扇和可拆卸蓋子
An integrated 2.79 (max) CFM fan, with fluid dynamic bearings selected for low noise and an extended operating lifetime, connects to the four-pin JST connector on Raspberry Pi 5 to provide temperature‑controlled cooling. Air is drawn in through a 360‑degree slot under the lid, blown over a heatsink attached to the BCM2712 AP, and exhausted through connector apertures and vents in the base.
We’ve lengthened the case, and tweaked the retention features, to make it possible to insert the Raspberry Pi 5 board without removing the SD card. And by removing the top of the case, it is now possible to stack multiple cases, as well as to mount HATs on top of the fan, using spacers and GPIO header extensions.

Ｃ．Active Cooler 冷卻風扇（鋁風扇、散熱片一體式）：－－另購
如果您希望您的 Raspberry Pi 5 能夠長時間、有效率地運作而不出汗，那麼您就該為它配備主動冷卻器了
Raspberry Pi 5 has been designed to handle typical client workloads, uncased, with no active cooling. Users who wish to use the board uncased under continuous heavy load, without throttling, have the option of adding a Active Cooler. This attaches to the board via two new mounting holes, and connects to the same four-pin JST connector as the case fan..
A radial blower, again selected for low noise and extended operating lifetime, pushes air through an extruded and milled aluminium heatsink. Both the case and the Active Cooler are able to keep Raspberry Pi 5 well below the thermal throttle point for typical ambient temperatures and worst-case loads. The cooling performance of the Active Cooler is somewhat superior, making it particularly suitable for overclockers.
【非必備】配件：
【Camera and display cables】－－另購
The new, higher-density pinout of the MIPI connectors means that an adapter is required to connect our own cameras and displays, and third-party products, to Raspberry Pi 5.
To support existing camera and display owners, we are offering FPC camera and display cables, which convert from the higher-density format (now referred to as “mini”) to the older lower-density format (now referred to as “standard”). These cables are available in 200mm, 300mm, and 500mm lengths．
Camera Module 3, the High-Quality Camera, the Global Shutter Camera, and the Touchscreen Display will all ship with both a standard-to-standard and a 200mm mini-to-standard cable.
【PoE+ HAT】擴展板－－另購
From early 2024, we will be offering a new PoE+ HAT. This supports the new location for the four-pin PoE header, and has an L-shaped form factor which allows it to sit inside the Raspberry Pi 5 case without interfering mechanically or disrupting airflow.
Prototype PoE+ HAT. We don’t know yet what the production version will look like, but we do know that it won’t look like this.
The new PoE+ HAT integrates a planar transformer into the PCB layout, and utilises an optimised flyback converter architecture to sustain high efficiency across the whole zero to 25W range of output powers.
【M.2 HATs】擴展板－－另購
One of the most exciting additions to the Raspberry Pi 5 feature set is the single-lane PCI Express 2.0 interface. Intended to support fast peripherals, it is exposed on a 16-pin, 0.5mm pitch FPC connector on the left-hand side of the board.
From early 2024, we will be offering a pair of mechanical adapter boards which convert between this connector and a subset of the M.2 standard, allowing users to attach NVMe SSDs and other M.2-format accessories. The first, which conforms to the standard HAT form factor, is intended for mounting larger devices. The second, which shares the L-shaped form factor of the new PoE+ HAT, supports mounting 2230- and 2242-format devices inside the Raspberry Pi 5 case.

【RTC battery】電池－－另購
Last, but very much not least, we have sourced a Panasonic lithium manganese rechargeable coin cell, with a pre-fitted two-pin JST plug and an adhesive mounting pad. This is priced and is suitable for powering the Raspberry Pi 5 real-time clock (RTC) when the main power supply is disconnected.
【Raspberry Pi Beginner’s Guide, 5th Edition】第５版書－－另購
Sporting a brand-new look and feel, and priced at RRP £19.99 , this new edition of our bestselling Raspberry Pi Beginner’s Guide is the definitive manual for Raspberry Pi computers and accessories. It has been comprehensively updated to cover Raspberry Pi 5, and the upcoming release of Raspberry Pi OS based on Debian Bookworm.
