eshinreal 4 Port SFF-8643 PCIe 3.0 x16 Adapter Card

SKU CH-YYB3-QVY1A

Adds four SFF-8643 ports for SAS, NVMe or SATA drives via a PCIe 3.0 x16 slot with 16GB/s bandwidth

  • Product typeController Card
  • Four SFF-8643 ports connect U.2 NVMe, SAS, or SATA drives
  • PCIe 3.0 x16 host interface delivers up to 16 GB/s total bandwidth
  • No driver installation needed — works across operating systems
  • LED activity indicators on each port show drive status
  • Compact 120 mm × 42 mm card fits standard expansion slots

Four-Port SFF-8643 Host Adapter

The eshinreal adapter adds four Mini-SAS HD connectors to a single PCIe 3.0 x16 slot. It targets builders attaching U.2 NVMe, SAS 12G or SATA III storage directly to the platform. The card operates without proprietary drivers on any operating system.

Passive Cooling and 12V Auxiliary Power

A four-pin 12V socket supplements slot power for attached drives. No onboard fan or active cooling is present, so airflow in the chassis determines thermals. The x16 electrical interface delivers up to 16GB/s aggregate bandwidth across all four ports.

Per-Port LED Status Indicators

Each SFF-8643 connector includes an activity LED that shows link and traffic state. The board measures 120mm by 42mm and fits a standard low-profile bracket. Cables, drive caddies or mounting hardware are not included.

Questions about this item

How do I install the eshinreal 4 Port SFF-8643 card and what step is often missed?

Insert the card into a PCIe 3.0 x16 slot and connect the 4-pin 12V power socket; the extra power connector is the step people forget.

What maintenance or replacement will the eshinreal adapter need later?

The card has no moving parts or batteries; only the attached SAS, NVMe or SATA drives may eventually require replacement.

What limit appears first on the eshinreal card during sustained use?

The PCIe 3.0 x16 host interface caps total bandwidth at 16GB/s, which is the first bottleneck under heavy multi-drive load.
