What are the system requirements for this adapter?

A computer with an available PCI Express x1 slot and operating system support (Windows, Linux, macOS). No additional drivers required.

Can I use a PCIe x16 graphics card with this adapter?

Yes, but the card will operate at x4 speeds due to the x1 upstream link. It is compatible for mining or non-intensive tasks.

Does the adapter require external power?

No, it draws power directly from the PCIe slot. However, high-power cards may need their own power connectors.

What brackets are included?

It comes with a low-profile bracket pre-installed and an additional full-height bracket for standard cases.

What is the maximum data transfer speed?

The adapter supports 2.5 GT/s per lane (PCIe Gen 1), resulting in ~250 MB/s per lane. Upstream is 1 lane, downstream is 4 lanes.

Is the adapter compatible with PCIe 2.0 or 3.0 slots?

Yes, it is backward compatible and will work in PCIe 2.0 and 3.0 slots, but will operate at the slot's highest common speed.

How do I install the adapter?

1. Power off and unplug your PC. 2. Open the case. 3. Insert the adapter into a PCIe x1 slot. 4. Secure with bracket screw. 5. Install desired PCIe card into the adapter's x4 slot. 6. Close case and power on.

What should I do if my card is not detected?

Ensure the card is fully seated, the adapter is properly inserted, and the card's power connectors are attached if needed. Try a different PCIe slot or update motherboard BIOS.
