PCIe 1X to Four USB 3.0 Multiplier Card

This adapter converts a single PCI Express 1X slot into four external PCI-E USB 3.0 ports for expansion cards. It is designed for cryptocurrency mining rigs that need multiple graphics cards or risers from one motherboard slot. The board measures approximately 120 by 66 by 21 millimetres and weighs about 41 grams. It ships without a retail package and includes the adapter card only.

Mining Rigs Needing Dense GPU Expansion

Builders assembling litecoin, antminer or bitcoin systems who want to attach several risers to a single 1X lane will find this card useful. It plugs directly into the motherboard without extra cables and can be secured to the chassis. Buyers who need powered risers with supplementary power connectors should look elsewhere because this unit draws all power from the slot. Users requiring a retail box or driver disc are not served by this package.

Lane Configuration Determines Bandwidth

The card splits one PCI Express 1X lane across four physical connectors so every attached device shares that single lane’s throughput. This works for mining workloads that tolerate reduced per-card bandwidth but will bottleneck gaming or compute tasks that demand full 16X speed. Verify your motherboard firmware supports bifurcation or device enumeration on a 1X root port before purchasing.

Questions about this item

Does my motherboard need a free PCIe x1 slot for this multiplier card?

Yes, the card plugs directly into a PCIe x1 slot on the motherboard and expands it to four external PCIe USB 3.0 connectors.

Can I use this card with a graphics card that only fits a PCIe x16 slot?

The four external slots are compatible with x1, x4, x8 and x16 cards, so a graphics card requiring a x16 mechanical slot will fit.

How can I verify the card is working after installation?

The operating system should detect each connected device in the PCIe device list; the card supports DOS, Linux and Windows XP through 10.
