Converts PCIe 3.0 x8 to Dual M.2 NVMe

This adapter card uses a PLX8747 chipset to split one PCI Express 3.0 x8 slot into two M.2 NVMe ports. Both drives run at full bandwidth simultaneously. The low-profile PCB fits most small form factor cases. It targets workstations and compact servers needing extra high-speed storage.

Suits builds with a free x8 slot needing two NVMe

Buyers whose motherboard only offers an x4 or x1 slot cannot use this card. Systems without PCIe 3.0 support will not reach the stated bandwidth. Anyone requiring more than two M.2 devices should look at a different expansion method.

Requires a physical PCIe 3.0 x8 slot for full

The PLX8747 controller divides the eight upstream lanes into two independent x4 NVMe paths. If the slot provides fewer than eight lanes, each drive loses bandwidth proportionally. Verify the slot length and electrical wiring before purchase.

Questions about this item

Do I need a PCIe 3.0 x8 slot on my motherboard to use this adapter?

Yes, the card requires a PCIe 3.0 x8 slot to provide two M.2 NVMe ports via the PLX8747 chipset.

Will my existing PCIe 3.0 x4 NVMe drives run at full speed when installed on this card?

The PLX8747 chipset maintains full bandwidth to both drives simultaneously so each x4 NVMe SSD operates at its rated PCIe 3.0 speed.

How can I verify both NVMe SSDs are detected and running at PCIe 3.0 x4 after installation?

Check the system BIOS or OS device manager; each drive should appear as a separate NVMe device running at PCIe 3.0 x4 link width.
