These cables are ideal for building GPU Servers requiring PCIe Connectivity for GPU's not directly slotted into the motherboard via SlimSAS ports on your motherboard.
This is typically done via x8 or x16 Device Adapters, this model has been validated on the popular CPayne SlimSAS PCIe gen4 Device Adapter x8/x16 with RTX 4090's.with impeccable signal integrity and performance.(yes the 1 meter cable)
We've used these with various ASRock Rack motherboards and Supermicro H12SSL motherboard models.
3M™ SlimLine Twin Axial Cable Assembly SFF-8654 8ESx Series is a high-performance cabling solution for PCIe applications, ideal for high-density data centers. This 3M cable features a low-profile ribbon construction that allows for bending and folding without compromising signal integrity, making it perfect for tight spaces. x8 configuration with length of 1 m, it supports PCIe (85 ohm) applications.
The 3M cable design helps optimize space utilization, enhances cooling by minimizing airflow obstruction, and streamlines system assembly. Each fold impacts impedance by no more than two to three ohms, ensuring excellent signal integrity even with multiple folds. The cable is without sidebands.
NOTE: We do not accept returns for used cables, please make sure this cable is suitable for your use case before purchasing. These cables are 85 ohm and do not have sidebands - they are not meant for PCIe tasks. Do not purchase for use related to RAID Controller / SAS / SCSI / Disk enclosures and related storage devices/protocols without properly researching compatibility. SlimSAS is not interchangeable with other SAS connectors (SAS / MiniSAS / etc) please make sure your hardware is meant to use SFF-8654 type connectors.
