This product not only supports laptops but also for Intel NUC motherboards, STX motherboards, ITX motherboards, mini PCS, external graphics cards, and adapter cards that support M.2 NVMe interfaces and PCIEx4 interfaces. NOTE:The speed of Gen5 requires support from the motherboard interface itself. K993G needs to be paired with R29Q/F4Q to achieve PCIe 5.0 x4 full speed.(Also Requires motherboard interface 5.0). Product Name: OCuLink SFF-8611 to PCIe x16 GPU Dock Transmission speed: PCIe 5.0x4, effective bandwidth 128Gbps Product application: It is used for external connection of graphics cards or other PCIe devices. Compared with the traditional for Thunderbolt adapter solution, the effective bandwidth of OCuLink under PCIe 5.0x4 can reach 128Gbps, far exceeding the for Thunderbolt solution. Friendly reminder: Most OCuLink devices do not support hot plugging. Please ensure that you perform plugging and unplugging with your device turned off Power supply description: Supports standard ATX power supplies. Please prepare the power supply specifications according to the instructions of the graphics card manufacturer Connector specification: Support cable to board application Small size design: pitch 0.5mm connector Supports 85 ohm impedance applications, 100 ohm is available on request Interface advantages: Compared with the for Thunderbolt external solution, the OCuLink external solution has a higher actual effective bandwidth. As it directly connects to the CPU through the PCIe channel, the performance loss is smaller. After the upgrade, OCuLink 5.0 can reach PCIe 5.0x4, with a maximum bandwidth of 128Gbps.
