SFF-8654 8i to 4x PCIe Gen 4.0 x4 adapter card with physical PCIe x16 connectors

This riser card converts an SFF-8654 interface into four PCIe x4 ports. The PCIe connectors on the card use an x16 physical format, but each operates as an x4 link.

It can also be used to extend a PCIe x16 slot by connecting it to an AIC card equipped with two SFF-8654 connectors, facilitating internal chassis expansion or reorganization.

Compatibility:

No drivers required: works natively with Windows, macOS, Linux, DOS, and other PCI Express-compatible systems.

Technical specifications:

2 PCIe 4.0 24G SFF-8654 8i 74-pin inputs.

4 PCIe x4 Gen 4.0 outputs (on x16 physical connectors).

High-quality Amphenol SMT connectors.

Low-loss PCB, 85 Ohm impedance.

Each SFF-8654 port provides 2 independent x4 links, allowing the use of a single link if only two ports are needed.

12V GPU-type power connector (ATX 2×3 Mini-Fit 5569).

6A buck regulator for 12V to 3.3V conversion.

Dimensions: 140 × 80 mm.
