Expansion capability
The SMUGDESK PH49 converts a single PCIe 4.0 x16 slot into four U.2 NVMe ports. It is designed for builders adding multiple high-speed drives to a workstation or server chassis. The card accepts SFF-8643 and SFF-8639 connectors for direct NVMe attachment. Full-height brackets fit standard enclosures.
Bandwidth and slot constraints
The adapter relies on PCIe 4.0 signalling across the x16 link to feed four downstream ports. Each drive receives an x4 electrical connection when the host slot provides sixteen lanes. Motherboards wired for only x4 or x8 will limit the number of active ports accordingly. The split function enables operation in those narrower slots.
Capacity headroom
Four U.2 bays allow dense NVMe storage expansion within one expansion slot. The design handles simultaneous access to all attached drives at PCIe 4.0 speeds. Systems needing more than four U.2 devices require additional host slots or a different backplane solution. Enterprise workloads benefit from the stable signal transmission.

Questions about this item
How many U.2 NVMe ports does the PH49 card provide from one PCIe 4.0 x16 slot?
The PH49 expands a single PCIe 4.0 x16 slot into four U.2 NVMe ports, letting you attach four U.2 drives at once.
What bandwidth does each U.2 NVMe port deliver when the card runs in a PCIe 4.0 x16 slot?
The PCIe split function divides the x16 lanes into four x4 links, so each U.2 NVMe port receives a full PCIe 4.0 x4 connection.
Which physical connectors does the PH49 use for its U.2 NVMe ports?
The card uses SFF-8643 and SFF-8639 interfaces for the four U.2 NVMe ports, matching standard U.2 drive cables.
