Ruth's sister PCIe 1x to 16x Riser 009S 4-Slot Port Multiplier Card

SKU CH-FX9T-JWJ2V

A PCIe 1x to 16x riser that splits one slot into four for mining rigs, using solid-state capacitors and a 6-pin power connector with 95% conversion efficiency

  • Expands one PCIe 1x slot into four 16x physical connectors
  • 95 % power conversion efficiency from integrated inductor and solid-state capacitors
  • 16 A maximum delivery through 6-pin graphics power interface
  • Four FP solid-state capacitors stabilise GPU voltage rails
  • Self-recovery fuse protects graphics card from over-current damage

PCIe 1x to 16x Port Multiplier

This adapter converts a single PCIe 1x slot into four 16x physical slots for expansion cards. It is aimed at miners who need to attach multiple graphics cards to one motherboard. The board includes 4 FP solid-state capacitors and an integrated inductor for stable power delivery. A 6-pin power connector supplements the slot with up to 16A capacity.

Bandwidth limited to 1x signalling

Although the physical slots are 16x, only a single lane of data is available from the host. Many devices will not recognise the link or will run at reduced throughput. The supplier notes that some equipment may fail to detect the card entirely. Buyers who need full 16x bandwidth per card cannot use this multiplier.

Solid capacitors and 6-pin power input

The onboard capacitors and inductor aim to protect the graphics cards from power irregularities. Conversion efficiency is stated at 95% for the power circuit. Correct cable orientation is critical; reversing or offsetting the connector can damage the hardware. Users must hold the socket firmly when inserting wires to avoid stressing the pins.

Questions about this item

Should I choose the 4-slot version of this riser?

The 4-slot multiplier lets you connect up to four graphics cards from a single PCIe 1x slot, which is the maximum density this model offers.

What does the 1x-to-16x label mean once the card is installed?

Only one PCIe lane is electrically active, so each attached GPU runs at 1x bandwidth regardless of the physical 16x connector size.

How does the PCIe 1x interface cap performance in practice?

The single-lane link limits throughput to 1x speeds, so high-bandwidth workloads will be bottlenecked while mining or compute tasks that tolerate low bandwidth can still run.
