Expands one PCIe x1 slot into four x16 slots using a 60 cm USB 3.0 cable and includes SATA power adapters for mining rigs
The Vszerda HXT-51X converts a single PCIe x1 slot into four PCIe x16 physical connectors using a USB 3.0 link. It targets mining rigs or test benches that need multiple GPUs or accelerators from one motherboard lane. No drivers are required for basic enumeration. The board draws auxiliary power from a 4-pin connector and includes two SATA 15-pin to 4-pin adapters for peripheral supply.
The riser uses an onboard IC power management device to regulate delivery across the four slots. External power enters through the 4-pin header and the bundled SATA adapters, keeping the motherboard slot within its rated current. The 60 cm USB 3.0 cable allows the expansion board to sit in open air, so GPU coolers exhaust freely without recirculating heat inside a cramped chassis. No active cooling is present on the riser itself.
The package supplies the x16 backplane, the x1 riser card, the 60 cm USB 3.0 cable and two SATA power cables. Connectors are keyed, but the supplier warns that misaligned insertion can damage pins, so the socket should be held during plug-in. The system must be powered off before any card is added or removed. The CE marking confirms the unit meets basic European safety requirements.

No published specifications for this item yet.
Power off the system, insert the 1X riser into the motherboard PCIe x1 slot, connect the 60cm USB 3.0 cable to the 16X board, attach the two SATA 15Pin-4Pin power cables to the board, then plug in your PCIe devices; the step often missed is connecting both SATA power cables before powering on.
The USB 3.0 cable and the two SATA 15Pin-4Pin power cables are the only wear items; inspect them periodically for connector fatigue or cable damage and replace if contacts become loose or insulation cracks.
The single PCIe x1 host link caps total bandwidth at one lane, so sustained throughput across all four slots is limited by that upstream bottleneck rather than the riser board itself.
