PCIe X4 to USB 3.0 Multiplier
This PCIe multiplier card converts a single PCIe X4 slot into four independent USB 3.0 ports for connecting GPU risers. It targets miners who need to expand graphics card installation positions beyond the native slots on a mining motherboard. The standard metal bracket fits most mining boards and accepts PCIe X4, X8, and X16 slots. Windows and Linux operating systems commonly used for mining rigs are supported.
Professional Multiplier Chip
A professional multiplier chip manages the 1-to-4 lane split to maintain steady data transmission during continuous mining runtime. This chip is the single specification that determines whether the card can sustain the bandwidth demands of multiple GPUs simultaneously. Without a dedicated multiplier, signal integrity typically degrades when one lane feeds four endpoints.
Four Riser Capacity
The adapter comfortably handles four PCIe 16X GPU risers connected via the USB 3.0 ports, allowing a single slot to serve four graphics cards. Bandwidth per GPU is shared from the original X4 link, so performance scales down when all four cards run heavy workloads at once. The design optimizes rig layout and internal heat dissipation for dense mining configurations.

Questions about this item
How many graphics-card risers can I attach through the four USB 3.0 ports?
Each USB 3.0 port accepts one PCIe 16X riser, so the card supports up to four graphics cards simultaneously.
Which slot widths on the motherboard will accept this multiplier?
The standard PCIe metal bracket fits PCIe X4, X8 and X16 slots on most mining motherboards.
What clearance does the bracket need at the rear of the case?
A single full-height PCIe bracket opening is required for the metal bracket to mount securely.
