P33 M.2 NVMe M-Key PoE+ Hat with Pi 5 Active Cooler - NVMe+PoE

Our review of the P33 M.2 NVMe M-Key PoE+ Hat finds it best suited for Raspberry Pi 5 users who need both fast onboard storage and a cleaner power setup. The biggest reason to consider this kit is the combination of a PCIe M.2 NVMe interface with Power over Ethernet capability and an included active cooler, which together upgrade a Pi 5 into a compact, cooled system with high-speed local storage. Assembly is straightforward and the aluminum case helps keep the board accessible while improving thermal performance.

Key Features

• Aluminum case: Provides a sturdy enclosure that leaves most Raspberry Pi 5 ports accessible while improving heat dissipation compared with a plastic shell.
• M.2 NVMe support: Accepts M.2 NVMe SSDs in 2230, 2242, 2260, and 2280 sizes to give the Pi fast, low-latency local storage for OS and data.
• PCIe M.2 interface: Uses the PCIe lane for high-performance communication between the SSD and the Raspberry Pi 5 for better throughput than USB storage.
• Power over Ethernet (PoE+): Allows powering the Raspberry Pi 5 through the Ethernet port to simplify wiring and centralize power management in networked deployments.
• 5.1V/4.5A output: Delivers sufficient power to the Raspberry Pi 5 and common peripherals without separate power adapters in many setups.
• Active cooler: The Pi 5 active cooler combines an aluminum heatsink and PWM fan to keep temperatures down under sustained load for reliable operation.

Who It's For

This package is aimed at hobbyists, home server builders, and networked Pi 5 projects that need local NVMe performance and cleaner cabling via PoE+. Users running media servers, small databases, or network appliances will value the NVMe speeds and integrated cooling.

It is less appropriate for absolute beginners who expect a fully finished case with only plug-and-play parts; some familiarity with installing a HAT, mounting an M.2 SSD, and routing PoE is helpful. If you only need a simple Pi enclosure without high-speed storage or PoE, a basic case may be a better, lower-cost choice.

Pros & Cons

Pros

• Combines M.2 NVMe storage and PoE+ in one HAT, reducing component clutter and cabling.
• The included active cooler and aluminum case improve thermal performance for sustained workloads.
• Supports multiple M.2 sizes (2230 to 2280), offering flexibility for different SSDs and capacities.
• Good build quality and clear assembly instructions make installation straightforward for an intermediate user.

Cons

• The metal case receives mixed feedback from users who prefer different cover materials, so aesthetics or feel may not match every preference.
• Someone new to PoE or M.2 installation may need time to follow the instructions and assemble the kit correctly.
