5.25" dual NVMe U.2 enclosure

The Athena Power BP-U22NVME525U fits a standard 5.25" bay and holds two 2.5" NVMe U.2 drives in a metal chassis. It is aimed at builders who want to add high-speed storage without using motherboard M.2 slots or PCIe adapters. No AC adapter is included; power comes from the system supply.

Tool-less drive installation with keylock

Drives slide into the slim modules and lock with the integrated keylock, so no screws or trays are required. The backplane carries the NVMe U.2 connectors and a USB 3.0 header for front-panel access. Installers must ensure the motherboard or controller supports U.2 signalling; a mismatched interface will leave the drives invisible.

Passive cooling under sustained load

The metal body acts as a heatsink for both drives, with no fan fitted. During long write sessions the enclosure relies on case airflow to keep temperatures in check. Builds with restricted front intake or tightly packed bays may see thermal throttling on heavy workloads.

Questions about this item

How can I verify the BP-U22NVME525U is functioning correctly after installing two NVMe U.2 SSDs?

The enclosure has no external interface or indicator lights; confirm operation by checking that each NVMe U.2 SSD appears in the system BIOS or operating-system disk utility after the 5.25" unit is secured and the 12V/2A and 3V3/0.5A power rails are connected.

What does the BP-U22NVME525U include and what must I source separately?

The package supplies the 5.25" metal backplane with dual NVMe U.2 slots, slim-size modules and a keylock; you must provide two 2.5" NVMe U.2 SSDs, a host adapter with the matching NVMe U.2 interface, and the 12V/2A plus 3V3/0.5A power connections.

Which capacity or version of the BP-U22NVME525U should I choose for my build?

Only one version exists — the BP-U22NVME525U part number — supporting two NVMe U.2 drives in a single 5.25" bay measuring 143.9 x 140.0 x 41.8 mm and weighing .505 kg; select it when you need exactly two bays in that form factor.
