A green circuit board with a white 16x PCIe slot connected by a flat flexible ribbon cable to a smaller 4x edge connector, 15cm long

LORDWORLD

LORDWORLD PCI-E 4X to 16x Riser Cable 15cm 4pin

SKU CH-NT8P-530XF

Extends a PCIe x4 slot to accept x16 cards at x4 speed with a 15 cm flexible riser and 4-pin power

  • Extends a PCIe 4x slot to full 16x length
  • 15 cm flexible FFC cable fits 1U 2U 3U chassis
  • 4-pin power layer on PCB board ensures stable supply
  • Supports 4x 8x 16x cards at 4x speed
  • Single-slot riser card with ribbon cable for compact builds

Purpose and fit

This LORDWORLD riser extends a PCIe 4x slot to accept a 16x card while delivering only 4x electrical bandwidth. It suits builders fitting expansion cards into 1U, 2U or 3U chassis where full-length slots are unavailable. Users who need full 16x throughput or multiple additional slots should look elsewhere.

Thermals, noise and power

The flexible FFC ribbon carries signals without active cooling, so it adds no fan noise to the system. A 4-pin power connector on the riser board supplies auxiliary current to the attached card, reducing load on the motherboard slot. Normal operation stays within the thermal envelope of the host chassis.

Included extras

The package provides the riser card and 15cm ribbon cable as a single assembly, with the 4-pin power interface already integrated on the board. No separate adapters, mounting brackets or driver software are supplied, so installation relies entirely on the host platform's native PCIe support.

Questions about this item

How do I install the 4-pin power connector on this 15 cm riser cable?

Connect the 4-pin plug from your PSU to the socket on the riser board before seating the graphics card; the step often missed is powering the riser itself, not just the GPU.

What maintenance will the flexible FFC cable need over time?

Inspect the ribbon for creases or dust every few months; reseat both ends if contact oxidises, but no scheduled replacement is required.

What bandwidth limit appears first when running a 16x card on this 4x link?

The electrical 4-lane connection caps throughput at PCIe 4x speeds, so the bus saturates before the card’s full 16x potential.
