LORDWORLD PCI-E 16X Riser Extender Card 20cm

SKU CH-M73H-DC205

Extends a PCIe 16x slot by 20 cm with a flexible ribbon cable and adds a Molex power connector for graphics cards

  • Extends PCIe 16X slots with 20cm flexible ribbon cable
  • Fits 1U, 2U, 3U chassis thanks to high-speed FFC cable
  • Supports 1X, 4X, 8X and 16X cards on single riser
  • Extra Molex power connector delivers 12V and GND to GPU
  • Single-slot 16X riser card keeps installation simple

PCI-E 16X riser for compact chassis

This 20 cm extender connects a PCIe 16X slot to a graphics card or other expansion board using a flexible flat cable. It fits 1U, 2U and 3U server cases where a full-height card cannot be installed directly. The board accepts 1X, 4X, 8X and 16X cards so a single riser covers several upgrade paths.

Signal integrity over a 20 cm ribbon

The high-speed flat cable maintains lane continuity for x16 electrical links without active retimers. Under sustained compute or mining workloads the passive trace length stays within specification, so throughput does not degrade after the initial handshake. No active components mean there is no firmware to stall or overheat during long runs.

Molex power keeps the slot fed

A standard Molex connector supplies 12 V and ground directly to the riser, offloading the motherboard slot during heavy GPU draw. The short cable run and lack of onboard voltage regulation keep parasitic losses low and eliminate fan noise entirely. Power consumption is limited to the passive PCB traces and the attached card itself.

Questions about this item

Does the 20cm ribbon cable add noticeable heat or power loss when the card runs continuously?

The 20cm flexible FFC cable carries PCIe 16X signals without active components, so it adds no measurable heat or power draw during all-day operation.

What power connector must my PSU provide for the extra Molex plug on this riser?

A standard 4-pin Molex (12V/GND) connector from the power supply is required to feed auxiliary power to the installed video card.

Will a legacy PCIe 1X or 4X expansion card function correctly in this 16X riser slot?

Yes, the riser supports PCIe 1X, 4X, 8X and 16X cards, so older 1X or 4X cards will work at their native speeds.
