ASUS ROG HYPER M.2 CARD 2-slot PCIe x16 NVMe drive enclosure

PCIe x16 NVMe expansion card

The ASUS ROG HYPER M.2 CARD adds two M.2 NVMe slots through a single PCIe x16 slot. It targets builders who want fast local storage on a desktop board that can bifurcate its top PCIe lane. The card supports PCIe 3.0 x2, PCIe 4.0 x2 and PCIe 5.0 x1 link widths per drive. It ships without a retail box but is unused.

Sustained throughput with bifurcation

Each slot runs at the speed negotiated by the motherboard's lane-splitting capability, so two drives share the x16 uplink without throttling each other. Thermal pads contact the controller and NAND to move heat into the aluminium heatsink during long writes. The open-fin design relies on case airflow rather than a dedicated fan. Performance scales with the PCIe generation the platform provides.

Motherboard bifurcation and clearance

Verify that your motherboard firmware exposes a PCIe bifurcation menu and can split the primary x16 slot into at least two x2 links. The card measures 21 by 10.5 centimetres and sits 1.5 centimetres tall, so confirm the slot spacing and any neighbouring cooler clearance. No extra power connector is required beyond the slot itself.
