Excellent performance with high customer satisfaction. Every unit undergoes 100% power-on inspection before shipment.

Brand: ADT Electronics
Model: K49SA
Product Name: PCIe 4.0 M.2 NVMe to SFF-8611 / SFF-8612 Riser Extension Cable
Bandwidth Speed: PCIe 4.0 x4 Gen4, Max. 64Gbps
Cable Length: 5cm - 25cm, custom cable length available

Purchasing Notice

We strongly recommend purchasing 1~2 samples first for testing and verification before bulk ordering.

Important Reminder: This product has potential compatibility risks. Incorrect assembly or improper operation may burn out your devices.
Purchase is restricted to professional engineers only.

Technical FAQQ: Can I shorten the PCB if it is too long?

A: Yes. The M.2-side PCB of K49SA can be cut along the white marked line indicated by the arrow. The minimum supported size is 2230.

Q: What is the mounting hole size for K49SA installation?

A: Fixed with M3 screws.

Q: Can ADT model K49SA-BK support PCIe 4.0?

A: Lab testing confirms full PCIe 4.0 speed. When used for eGPU dock connection, the 3DMark benchmark result only has a 0.01% difference compared with direct plug-in connection.

Q: What about cable quality? Does it have shielding?

A: It adopts metal-layer shielding with advanced EMI shielding conductive polymer and flat ribbon cable design. The entire cable is fully covered with conductive polymer EMI shielding layer, which blocks incoming and outgoing electromagnetic radiation, minimizes interference and performance degradation, and reduces cable weight.

Q: Cable thickness? Is it flexible and bendable?

A: This cable is ADT’s 5th generation PCIe dedicated cable, thin black version. Cable thickness is only 0.8mm. It is soft and bendable without affecting normal use.
