Four-bay U.2 NVMe backplane for 5.25" bays

The Athena Power BP-U24NVME8525 fits a standard 5.25-inch bay and holds four 2.5-inch NVMe U.2 drives. A metal frame with stainless carriers and a sliding tray design allows tool-free drive swaps. Two 4020 fans provide active cooling across all bays. The unit connects via four Mini SAS HD SFF-8643 ports and draws power through two 15-pin connectors.

Suits builders adding high-speed U.2 storage

This backplane serves workstations and servers that need four hot-swappable NVMe drives in a single external bay. Vibration-reducing springs on each tray protect drives during operation. A built-in keylock secures the carriers against unauthorised removal. Buyers whose systems lack a free 5.25-inch bay or Mini SAS HD host ports cannot use this enclosure. It also does not support drives larger than the 2.5-inch form factor.

Four Mini SAS HD SFF-8643 ports for host connection

Each of the four drive bays routes through a dedicated Mini SAS HD SFF-8643 connector to the host controller. The interface supports U.2 Gen3 at 32Gbps and Gen4 at 64Gbps performance per drive. No external interface is present on the unit itself. Verify that your host adapter or motherboard provides the required number of SFF-8643 ports before purchase.

Questions about this item

Will this 5.25" backplane fit my case's front bay and how much depth does it need?

The unit measures 159 x 145.8 x 41.6 mm and occupies a single 5.25" bay; verify your case has at least 159 mm of clear depth behind the bezel.

Which cables connect the four U.2 drives to the motherboard and how are they keyed?

Four Mini SAS HD (SFF-8643) ports carry the NVMe signals; each port maps to one carrier, so plug each cable into the matching motherboard or HBA port before sliding drives in.

What cooling maintenance will the dual 4020 fans require over time?

The two 4020 fans pull air through the carriers; clean dust from the fan intakes and heatsink fins every few months with compressed air to maintain airflow.
