Internal M.2 / U.2 adapter card DELOCK 90854 — PCIe 4.0 (host: PCIe, outputs: M.2 Key M 110 mm, U.2)

DELOCK 90854 is an internal PCIe 4.0 expansion adapter card that provides a PCIe host connection and exposes one M.2 Key M slot (110 mm) and one U.2 interface. The card supports NVMe drives and is designed to add high‑speed internal storage to compatible desktop, workstation and server systems. It is supplied as a single unit in a black and silver finish and fits into a standard PCIe expansion slot to enable low-latency, high-bandwidth NVMe connectivity.

Advantages

This adapter card supports PCIe 4.0 signalling to take advantage of higher throughput when paired with a compatible motherboard and CPU. It accepts M.2 Key M modules up to 110 mm and also provides an internal U.2 connection for 2.5" NVMe drives, offering flexibility between M.2 and U.2 form factors. The internal design keeps drives mounted inside the chassis for improved cable management and system airflow compared with external enclosures.

How to use

Install the card into an available PCIe x4 or larger slot on a compatible motherboard and secure it to the chassis. Mount an M.2 NVMe module into the M.2 Key M socket and fasten it with the appropriate standoff and screw, or connect a U.2 NVMe drive to the U.2 internal connector using the corresponding cable if required. Ensure the system BIOS/UEFI supports NVMe boot or storage devices and update firmware or drivers as recommended by the motherboard and SSD manufacturers. Verify drive detection in the firmware and operating system before partitioning or formatting.

Recommendations

For optimal performance, pair the DELOCK 90854 with a motherboard and CPU that support PCIe 4.0 lanes on the chosen slot. Observe anti‑static precautions during installation and confirm chassis clearance for the chosen M.2 length or U.2 drive. When using the card in critical systems, keep firmware for the SSD and system BIOS up to date and perform regular backups.
