USB 3.0 PCI-E Riser Adaptor

Basic Function & Use

This adaptor connects a PCIe x16 card (like a GPU) via a PCIe x1 motherboard slot using a USB3.0 cable as an extender. Often paired with a SATA or 6pin power input to supply GPU voltage and stability

Electrical & Data Specs

• Interface Compatibility: PCIExpress 1.0/2.0; supports x1, x4, x8, x16 on slot side and x1 host-side

• Data Rate: Max ~5Gbps (USB 3.0 bandwidth), roughly equal to PCIe 1.0 x1 (250MB/s)

• Power Delivery: Supported via SATA 15pin or 6pin PCIe input on riser board; some even include Molex or dual power options

• Capacitors: Typically equipped with 4 solid-state capacitors to ensure voltage stability under load

Physical Characteristics

• USB Cable Length: Usually ~55—60cm (spec extensions up to ~3m possible, but greater chance of signal integrity issues)

• Riser Board Dimensions: ~130×43×15mm (e.g., DELock design)

• Connector Surfaces: Gold-plated contacts for improved durability and signal conduction

Compliance & Compatibility

• USB 3.0 Standard: Uses SuperSpeed protocol @5Gbps with standard TypeA plugs

• PCIe Standard: Backward-compatible with PCIe 1.x and 2.x links; behaves electrically as a PCIe 1.0 x1 link

• Plug-and-Play: No drivers required—simply insert card and power it

Considerations & Tips

• This type of riser provides bandwidth similar to PCIe 1.0 x1, which may bottleneck high-speed GPUs—acceptable for crypto mining or lower-demand tasks, but not ideal for gaming

• Stick with the supplied ~60cm USB cable—longer aftermarket cables may compromise signal integrity and cause errors

• Ensure your PC case or mining frame has proper cable strain relief to avoid loosening connectors during use.

Final Word

These USB3.0 PCIe risers are cost-effective, simple, and widely used in GPU setups—offering ease of installation with sufficient bandwidth for many tasks. Just be sure to power the board correctly and use the specified cable length for best results.
